Marine life

Our ocean, coasts, and estuaries are home to diverse living things. These organisms take many forms, from the tiniest single-celled plankton to the largest animal on Earth, the blue whale. Understanding the life cycles, habits, habitats, and inter-relationships of marine life contributes to our understanding of the planet as a whole. Human influences and reliance on these species, as well as changing environmental conditions, will determine the future health of these marine inhabitants. Toxic spills , oxygen-depleted dead zones, marine debris , increasing ocean temperatures, overfishing, and shoreline development are daily threats to marine life. Part of NOAA's mission is to help protect these organisms and their habitats.

Food webs describe who eats whom in an ecological community. Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly.

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales. Top ocean predators include large sharks, billfish, dolphins, toothed whales, and large seals. Humans consume aquatic life from every section of this food web.

Coral reefs are some of the most diverse ecosystems in the world. Coral polyps , the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms. Thousands of species of corals have been discovered; some live in warm, shallow, tropical seas and others in the cold, dark depths of the ocean.

Seafood plays an essential role in feeding the world’s growing population. Healthy fish populations lead to healthy oceans and it's our responsibility to be a part of the solution. The resilience of our marine ecosystems and coastal communities depend on sustainable fisheries.

Estuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.

Marine mammals are found in marine ecosystems around the globe. They are a diverse group of mammals with unique physical adaptations that allow them to thrive in the marine environment with extreme temperatures, depths, pressure, and darkness. Marine mammals are classified into four different taxonomic groups: cetaceans (whales, dolphins, and porpoises), pinnipeds (seals, sea lions, and walruses), sirenians (manatees and dugongs), and marine fissipeds (polar bears and sea otters).

Sea turtles breathe air, like all reptiles, and have streamlined bodies with large flippers. They are well adapted to life in the ocean and inhabit tropical and subtropical ocean waters around the world. Of the seven species of sea turtles, six are found in U.S. waters; these include the green, hawksbill, Kemp's ridley, leatherback, loggerhead, and olive ridley.

The Ocean: Life Below Water and Why it Matters

Key questions >>>

• Why does the ocean matter? How is the ocean important for sustainable development?
• What does the sustainable blue economy offer us?
• What are the ocean knowledge gaps?
• How do we need to develop a multidisciplinary ocean science?

The ocean covers around three-quarters of the earth's surface and contains more than 90% of living species on our planet. The ocean is also the single largest ecosystem in the world, and it provides food for billions of people worldwide, as well as maritime transport, renewable energies, and other goods and services like regulating, cultural and supporting services. 

Nevertheless, the ocean is not indestructible, and our footprint is very large. Overfishing, toxic pollution, invasive species, nutrient over-enrichment, habitat degradation and destruction, biodiversity loss, dependence of a growing global population on its goods and services, and coastal development, all threaten the sustainability of coastal ocean ecosystems ( Vanderweerd in Sherman and McGovern, 2011). Ocean acidification is also a growing threat that may be more important than warming, pollution and overfishing (Roberts, 2011).

Why Does the Ocean Matter?

Oceans mean different things for different people: life, passion or wonderment; vastly important; a very important source of life and energy; an incredible source of food and amazing source of biodiversity; it's wild, exciting, terrifying and exhilarating; means a lot to me, if something happens I will not have the fun I’m used to; it's a livelihood, it's been there for generations and hopefully will be there for generations to come.’ (Adapted from video excerpt, Plymouth Marine Laboratory, 2011, in Muñoz-Sevilla and Le Bail 2017).

According to the World Wildlife Fund, the ocean is currently valued at $24 trillion dollars. The goods and services from marine environments add up to an additional $2.5 trillion yearly. This means the ocean would have the seventh-largest GDP in the world.  However, the value of the ocean relies on its current output, which in turn depends on its conditions. Climate change, ocean acidification, habitat destruction, pollution and overfishing are endangering the ocean and threatening its value and the security and livelihood of the three billion people who depend on it. Most of these people live in Small Island Developing States, they are among the ones who contribute least to these issues, but they are the ones at most risk, as they’re already vulnerable. ( Hoegh-Guldberg 2015)

Agenda 2030: SDG 13 and SDG 14

A historical change has been taking place for the past 23 years, from Agenda 21 to Agenda 2030. At the Rio de Janeiro Earth Summit in 1992, more than 178 countries adopted Agenda 21. The Millennium declaration was adopted after the 2000 Millennium Summit in New York. 10 years after the Rio Earth Summit, in the Millennium Development Goals (MDGs) that were adopted during the Earth Summit in Johannesburg, ocean issues were included in the conversation for the first time. 

In 2012, at the United Nations Conference on Sustainable Development (also popularly known as Rio+20), member states adopted the document titled “The Future We Want”, which set the process of developing the sustainable development goals (SDGs) building on the MDGs. Finally, during the UN Sustainable Development Summit in 2015, seventeen SDGs were adopted which are an integral part of the 2030 Agenda.  

Progress of SDG 14 in 2019

The expansion of protected areas for marine biodiversity and existing policies and treaties that encourage responsible use of ocean resources are still insufficient to combat the adverse effects of overfishing, growing ocean acidification and worsening coastal eutrophication. As billions of people depend on oceans for their livelihood and food source, increased efforts and interventions are needed to conserve and sustainably use ocean resources at all levels. 

• Ocean acidification is caused by the uptake of atmospheric CO 2 by the ocean, which changes the chemical composition of the seawater. Long-term observations over the past 30 years have shown an average increase of acidity of 26 percent since pre-industrial times. At this rate, an increase of 100 to 150 percent is predicted by the end of the century, with serious consequences for marine life. 
• To achieve sustainable development of fisheries, fish stocks must be maintained at a biologically sustainable level. Analysis reveals that the fraction of world marine fish stocks that are within biologically sustainable levels declined from 90 percent in 1974 to 66.9 percent in 2015. 
• As of December 2018, over 24 million km 2 (17.2 per cent) of waters under national jurisdiction (0–200 nautical miles from a national border) were covered by protected areas, a significant increase from 12 percent in 2015 and more than double the extent covered in 2010. The protected areas increased from 31.2 per cent in 2000 to 44.7 per cent in 2015 and to 45.7 per cent in 2018. 
• Illegal, unreported and unregulated fishing remains one of the greatest threats to sustainable fisheries, the livelihoods of those who depend upon them and marine ecosystems. Most countries have taken measures to combat such fishing and have adopted an increasing number of fisheries management instruments in the past decade. 
• Small-scale fisheries are present in almost all countries, accounting for more than half of total production on average, in terms of both quantity and value. To promote small-scale fishers’ access to productive resources, services and markets, most countries have developed targeted regulatory and institutional frameworks. However, more than 20 per cent of countries have a low to medium level of implementation of such frameworks, particularly in Oceania and Central and South Asia.

The Ocean Decade

To recognize that more needs to be done to mitigate the global decline in ocean health, in December 2017, the UN declared 2021 to 2030 as the decade of ‘Ocean Science and Sustainable Development’. 

The Ocean Decade will strengthen international cooperation in all levels by strengthening dialogues, developing partnerships, developing capacity-building and leveraging investment, while supporting the entire 2030 Agenda for sustainable development. Other critical goals include improving ocean literacy and education to modify social norms and behaviors, and creating new models for ocean action.

The Ocean Decade aims to include science-informed mitigation and adaptation policies around the world and share knowledge with coastal communities who are most vulnerable to the changes of the ocean. (Claudet et al. 2019)

The COVID-19 Pandemic and the Ocean 

From Little Blue Letter, Glen Wright

• Marine creatures are enjoying some quiet time as underwater noise levels drop. Scientists are studying these effects on marine mammals.
• ​From Florida to Thailand, the number of sea turtles nests has increased on the now-empty beaches. The rapid recovery of marine wildlife in coastal areas shows how extensive our impacts are and highlights the importance of protected areas. 
• Fishers around the world are struggling with decreased demand, lack of sanitary conditions and logistical challenges. In some countries, like India, food security of the communities may be affected by this disruption of supply chains.
• PADI and Rash’R are producing (non-profit)  reusable face masks made from Ocean plastic , with designs based on sea animals!

Final Remarks

We can all take small steps towards protecting our ocean. Reduction of single-use plastic, responsible fish consumption, avoiding ocean harming products, and making your voice heard can all directly contribute towards a healthier ocean. However, more indirect approaches can be taken by reducing the amount of greenhouse gases produced by our daily activities and, therefore, reducing our carbon footprint. Reducing red meat consumption, consuming locally sourced products and using personal vehicles less are all examples of small steps we can take towards reducing our impact. The sum of individual actions can truly make a difference in the fate of our ocean.

Collectively, we need to form a global ocean community, acknowledging that all of our actions have an impact on the ocean (Claudet et al. 2019). And, although it is incumbent on each of us to take steps to protect the ocean, collective action is also required. New models for ocean action, which are collaborative, intergenerational, cross-cultural, and multi-sectoral, are needed in the coming decade, in order to protect our beloved ocean. 

The ocean is our life support system, it connects every one of us, you can think of the ocean as the blue heart  of this planet, but then we look after that heart and we know how we are damaging it and it needs intensive care. We know that scientists, politicians and stakeholders are talking to each other, but it isn’t just up to them, each and every one of us can make the difference, even if the difference might be small, after all individual small drops of sea water can make up the vast ocean . (Adapted from video excerpt, Plymouth Marine Laboratory 2011, in Muñoz-Sevilla and Le Bail 2017).

What Is Marine Life And Its Importance? Facts & Statistics

Reading time: 8 minutes

The Earth’s oceans are home to millions of animal and plant species, as well as potentially millions more that are so far undiscovered. They are delicately balanced ecosystems and their healthy function is key to the balance of all life on Earth. Many people see marine life as something altogether separate to life on land but the two are far more connected than we might think. Crucially, the behavior and choices made by people seriously impact the wellbeing of our aquatic friends.

What Is Marine Life?

Marine life refers to all the animals, plants and organisms that live in Earth’s saltwater seas and oceans. From the smallest plankton to the largest whale, all organisms play a role in the healthy function of these amazing, complex ecosystems.

Coral Reef Ecosystems

Coral reefs are diverse, colorful and home to millions of marine species across the planet. They provide a natural barrier to the power of the ocean, protecting coastal communities from extreme weather events such as tsunamis. As food chains, they are extremely important, providing an area in which marine species can live, feed, raise their young and thrive.

Unfortunately, they are also highly vulnerable to ocean temperature change, a direct result of climate breakdown. In 2016, Australia’s Great Barrier Reef experienced a 30 percent loss of coral reef due to a nine-month marine heatwave, the largest reef loss ever recorded. The fishing of reefs has also led to species loss, as food chains are interrupted and predators cannot survive.

Some examples of the largest reef ecosystems on earth include:

• The Great Barrier Reef, Australia
• The Red Sea Reef, Egypt, Sudan and Eritrea
• New Caledonia Barrier Reef, southwest Pacific Ocean
• Florida Reef, USA
• Andros Coral Reef, the Bahamas

Ocean Fishes

There are thousands of different species of ocean fish, yet populations are continually declining as we allow commercial fleets to fish our oceans. Atlantic cod, for example, can live up to 25 years, yet their populations are now at critically low levels. Some other ocean fish include:

• Barramundis

Marine Mammals

Marine mammals are generally larger sea creatures, who live underwater but need to breathe air also. Around the world these marine mammals still lose their lives unnecessarily due to habitat loss, being caught and killed by fishing fleets (“ fishing bycatch ”), hunting and noise pollution.

• Marine mammals include:

Sea Turtles And Reptiles

Reptile life in the sea is largely made up of turtle species such as:

• Loggerhead turtles
• Hawksbill sea turtles
• Green sea turtles
• Leatherback sea turtles

All seven species of sea turtles are endangered or critically endangered with The World Wildlife Fund stating that “the single biggest threat to most sea turtles is fishing gear.”

Marine iguanas and saltwater crocodiles are also ocean-dwelling species of reptile. Reptilian life in the sea is particularly vulnerable to pollutants such as plastic, as these animals live in shallow seas and come into contact with human populations often.

Cephalopods, Crustaceans And Shellfish

Cephalopods, crustaceans and shellfish play an important role in ocean ecosystems and the marine food chains, and includes:

• Cuttlefishes

They are particularly vulnerable to increased ocean acidification, a direct result of increased human-generated greenhouse gas emissions.

Seabirds are found on coastlines, in coastal waters and far out at sea, and include species such as:

• Albatrosses
• Fish eagles

Seabirds play a vital role in marine ecosystems but populations have dropped by 70 percent since the middle of the 20th century, with campaigners saying that they are being pushed to the brink of extinction by the fishing industry. Habitat destruction and pollution also play a part.

Why Marine Life Is Important?

The oceans provide 50 percent of the world’s oxygen and they provide essential ecosystem services that allow our planet to function in a healthy way. For example, ocean currents govern our weather systems, and if they were to be interrupted, the extreme weather consequences would be drastic. The oceans can only provide these services by maintaining delicately balanced ecosystems, made up of food chains and biological systems. Human activity risks the shutdown of essential ecosystem services that we rely on to survive.

One example is coral reefs. When we fish around coral reefs, those reefs’ delicate ecosystems are damaged and often die. We then lose the essential service a coral reef provides such as protection from erosion and weather, biochemical regulation, and recreation. This is just one of the reasons why taking care of the oceans is essential for our own wellbeing.

Marine Life Facts And Statistics

• An estimated 50-70 percent of all life on Earth is found under the oceans
• Humans have explored roughly 10-20 percent of the ocean
• There are around 230,000 classified marine species, but as many as two million or more yet to be discovered
• Marine biodiversity is declining at an alarming rate. It is estimated the oceans suffered around a 50 percent species loss between 1970 and 2012

Marine Life Pollution

Humans continue to pollute the oceans, despite the huge risks to marine life and to ourselves. Marine pollution comes in many forms such as plastic pollution, acidification and oil spills.

How Does Ocean Acidification Affect Marine Life?

Ocean acidification occurs due to increases in carbon dioxide in the atmosphere (due to climate warming) and it can have terrible consequences for marine life, particularly crustaceans. Higher acidity in water results in shells dissolving more quickly, which of course has a devastating impact on shellfish and other crustaceans. This can have drastic knock-on consequences for other animals who rely on them for food, and throw marine food chains and whole ecosystems out of balance..

How Do Fisheries And Seafood Affect Marine Life?

Probably the largest risk posed to marine life is the fishing industry. Vast commercial fleets trawling the oceans has been common practice for many years and sadly shows no signs of slowing. The negative impacts for marine life are huge and includes:

• Fish population crashes which impacts every species that live in the oceans. Bycatch from fishing nets results in huge biodiversity loss, including driving species to the brink of extinction.
• There is evidence to show that catching fish causes pain and is hugely distressing for those caught and those left behind.

How Does Fish Farming Affect Marine Life?

Fish farming poses various environmental and welfare risks including:

• Disease is easily spread in fish farms and too often spreads beyond the farm into the natural environment.
• Fish farms pollute waters with the chemicals needed to treat diseases caused by the appalling conditions, excess feed and concentrated fish waste. This pollution causes algal blooms, resulting in the deaths of wild fish, too.
• Wild marine animals, such as seals, are inevitably attracted to fish farms as a potential source of food, but these animals are often killed deliberately by farmers to stop them eating the valuable fish.

How Does Human-generated Noise Pollution Affect Marine Life?

Natural soundscapes in the ocean are key for healthy marine life, as animals use sound to communicate, catch food, navigate, defend themselves and attract mates. Machinery like boats, jet skis or oil drills create an unnatural barrier to marine life’s natural soundscape, and the impacts can devastating:

• Marine mammals like whales use complex songs to communicate, navigate and attract one another. If these are interrupted, they cannot enact basic natural functions and die as a consequence
• Animals can be directly stressed by unnatural noise, leading them to make poor decisions that can lead to their deaths

Other Forms Of Pollution?

Plastic pollution is the other major form of marine pollution that affects marine life:

• Plastic waste can entrap marine animals resulting in them drowning, starving or being eaten
• Soft plastics and microplastics can be ingested by marine life and cause their deaths
• Plastic pollution kills 100 million marine mammals and up to a million seabirds every year
• Most plastic pollution comes from the fishing industry

How Can We Save Marine Life?

Put simply, we can save marine life by leaving the oceans alone and letting their ecosystems operate naturally. These systems have developed over millions of years of evolution and they can only operate without our intrusion.

We can reduce our impact on marine life in a few ways:

• Go vegan. Stopping consumption of marine animals is the single biggest way to help the oceans. It would stop overfishing and bycatch, returning fish populations to healthy levels. It would also reduce noise pollution from fishing vessels, reduce oil spills and plastic pollution from fishing fleets, and lower carbon dioxide levels, thereby reducing ocean acidification
• Reduce our consumption of all unnecessary products and buy local as much as we can – global shipping networks create noise and chemical pollution in the oceans, which directly affects marine life
• Reduce our reliance on plastics, stop buying single-use plastic items, and recycle plastic waste effectively, so that it never ends up in the ocean
• Raise awareness of the issues – watch and share documentaries such as Seaspiracy to alert others of the need to save marine life

Healthy marine life is critical to the healthy function of the whole planet and to the lives of all those who inhabit it. Without healthy balanced oceans, many of our essential ecosystem services would collapse, resulting in terrible knock-on effects for humans and animals alike. But that is not the only reason to protect marine life. We should protect them for their own sake. The lives of marine animals are as important to them as ours are to us. They are here on Earth with us, not for us.

ENCYCLOPEDIC ENTRY

Aquatic biome.

The aquatic biome is divided into freshwater and marine regions. Freshwater regions, such as lakes and rivers, have a low salt concentration. Marine regions, such as estuaries and the ocean, have higher salt concentrations.

Hawksbill Turtle

Brian J. Skerry

The aquatic biome is the largest of all the biomes , covering about 75 percent of Earth’s surface. This biome is usually divided into two categories: freshwater and marine . Typically, freshwater habitats are less than 1 percent salt. Marine life, however, has to be adapted to living in a habitat with a high concentration of salt. Freshwater habitats include ponds, lakes, rivers, and streams, while marine habitats include the ocean and salty seas.

Ponds and lakes are both stationary bodies of freshwater , with ponds being smaller than lakes. The types of life present vary within lakes and ponds. In the shallow, sunny waters there is an abundance of life, such as various species of fish. In the deep, dark waters, however, decomposers thrive.

Rivers and streams are moving bodies of freshwater . The water in a river or stream is largely made up of runoff from sources such as melting glaciers or rainwater. Rivers and streams usually empty into a lake or the ocean. At the beginning of a fast-moving river or stream, the water is clear and oxygen is abundant. As the water flows, however, it may pick up debris, making the river or stream increasingly cloudy. Oxygen levels may subsequently be affected.

The ocean is a large body of saltwater that spans most of Earth’s surface. Like ponds and lakes, life in the ocean is adapted to certain regions of the water. For example, the deepest parts of the ocean are too dark to support photosynthesis , but many creatures still manage to survive here. In these regions, the food chain is based on bacteria that perform chemical reactions to obtain energy, also called chemosynthesis . In shallow ocean waters, coral reefs can form. These structures look like shelves of rock, but they are actually made of living animals, called corals, with a calcium carbonate skeleton. Coral reefs are incredibly diverse, hosting over a thousand species of fish. Currently, coral reefs are in danger due to human-caused climate change , which has led to the ocean growing hotter and more acidic.

Estuaries are regions where freshwater and ocean water mix. Life in estuaries must be adapted to this mixture of saltwater and freshwater. Estuaries are home to many species of fish and shellfish, as well as several species of migratory birds that depend on estuaries for a place to nest and raise their young.

Essay on Aquatic Animals (510 Words)

Aquatic lives are much different than normal terrestrial lives. Aquatic animals are those that live inside water. They have a provision in body to make their respiration. These aquatic animals are especially characterized as the one who don’t get a close contact with the world outside water.

Fish is one good example of aquatic animal. There are many types of aquatic animals. If these animals are in contact with the outer world in the absence of water they can not breathe they die every soon within few minutes. Fish consumes oxygen from inside the water molecules. They can not breathe oxygen normally from the outside air.

Many people use fish as their food, but this aquatic animal life is in danger because of continuous decline in their population.

Image Source: upload.wikimedia.org

There are many factors that cause harm to the aquatic animal’s life. One main reason is the water pollution. Man is the only intelligent animal on earth blessed with the ability to think rationally. But this man has disturbed the life cycle of aquatic animals because of his indiscriminate activities. Many manufacturing companies spread their chemicals, wastages and experimental products inside water.

This pollutes the water which is home to the aquatic life. As a result, fishes are unable to breathe even inside water. Polluted water lacks oxygen inside and thus many fishes die even inside water. It is necessary to think on this issue as the aquatic animals and their life are in danger because of man’s mistakes.

Aquatic animals involve not only fishes but many other animals. There are many types of snakes also that live inside water. These snakes are also a part of aquatic life. These snakes can be categorized as the aquatic animal. Apart from snakes there are many types of turtles. But turtles, crocodiles and frogs are amphibians that can live inside water as well as on ground because they have got provision inside their body to be able to breathe both inside water as well as on ground.

It is responsibility of every human being to take care of aquatic animal and their lives. These species are depleting day by day. If this decline is not stopped right away, soon they will vanish completely.

Aquariums play an important role in this regard. These aquariums are designed to sustain aquatic lives. Aquatic animals are limited and if they also get depleted, the next generation might not see them. So it is necessary to take quick actions against the extinction of aquatic animals.

Aquatic animals and their life vary to a great extent than terrestrial animals. If these animals are not preserved properly, they will not persist in near future and this will directly affect the entire life cycle of this world. The basis of entire food chain of this world is supported by these aquatic animals; if their lives get disturbed then for sure food chain will get affected adversely.

Therefore it is necessary to take good care of aquatic animals and their lives, this will maintain a balance of overall life cycle of living beings.

The global economy of today is casting its effect on the earth’s capacity to maintain life’s abundance. What we see around is not promising, and it shows the need for reorientation. The focus is fast shifting on the relation between nature and the humans. The humans with their activities are destroying the very plant they live on. The aim is to look for the right ways to live on the life-giving planet, by having the right relationship. New understandings are fast emerging to understand the relationship between humans and nature. TAC or Thames Anglers’ Conservancy is a voluntary organization founded in 2010 with the objective of conservation of the River Thames. The members of the organization are well familiar with the river and have noticed how the river and its habitat has changed over time. Still, the river faces several challenges and population of eel have crashed. On the other hand, populations of invasive species like American Signal Crayfish and Chinese Mitten Crabs have damaged the ecology of the river. The potential impact of illegal fishing methods, poaching and Thames HydroPower projects need to be measured. TAC campaigns against sewage entering the Thames and how the untreated sewage is leading to a serious environmental problem. There are efforts to improve and increase the Mogden Sewage Treatment Works. TAC is getting stakeholders, conservation organizations, Environment Agency, river user groups, and local councils to come together in their efforts to make the Thames a safer environment. Together with Angling Trust, it fights pollution and poaching as well as other issues that are damaging the aquatic environment (Anglers dedicated to protecting and improving the River Thames 2016). The River Thames has been a high-profile project regarding improvements to the water quality and restoring Atlantic salmon. It has been observed that restoration of certain species of plants and animals is getting common around the world, and one good example is the Atlantic salmon. The efforts are seen as a response to the severe decline in the populations of salmon in rivers. The continued decline was attributed to environmental changes within rivers, happening because of exploitation of land and water resources by humans. Atlantic salmon not only holds a sporting and commercial value but remains a key indicator of the quality of water and ecosystem health as asserted by Griffiths et al. (2733). The data on fish abundance and their environmental conditions collected over a decade shows substantial variation in the abundance. The general pattern is a trend of deterioration over the years. One of the main reasons is rapid urbanization and industrialization of Greater London that has led to pollution. The results are a decline in fish and other biota as stated by Araújo, Williams, and Roland (305). It has bene observed that an improved effluent quality of the major Sewage Works led to an increase in fish population and species diversity. Seasonal variation influences the marked cycles of fish abundance in environmental conditions and the biological indicators of water quality (Araújo, Williams and Roland 306). The effect of pollution alters the diversity and the abundance of species as well as deteriorates fish habitat as reported by Araújo, Williams, and Roland (316). There are limitations to the recent attempts of genetically assigning Thames, salmon to northern populations. However, the results support that salmon caught in the Thames have strayed from other rivers. This indicates the need of making concerted efforts for improving river quality and habitat, rather than just focusing on long-term stocking of the endangered species (Griffiths et al. 2737). Again, it is the right balance of relation between the humans and the nature that can help restore ecosystem functioning and continuity, and not just focus on the immediate habitat of the species. This will encourage the populations of salmon to reestablish naturally. The above discussion shows how the relation between the human and nature can make the biotic environment change for the better or worse.

Water Is Life Essay

Essay on Water Is Life - We must comprehend the value of water in our life and the need to preserve it. There are numerous easy ways to prevent water waste, including taking shorter showers, watering plants with RO waste, cleaning cars with a wet cloth rather than a hose, etc. Here are 100, 200 and 500 word essay on “Water Is Life”

All life forms on earth require water in some capacity in order to function. It is safe to claim that the existence of water makes Earth the only planet capable of supporting life. One of our most important resources on earth is water. Water is essential to life, and we cannot exist without it. Not just humans, all forms of life on Earth consumes water in some form or other, as water is essential for organisms to survive. Here are some sample essays on “Water Is Life”

100 Words Essay On Water Is Life

Life is water. Water is a necessity for all life on Earth. Animals need water to quench their thirst, plants need water to draw nutrients from the soil and keep nourished, and people need water for a variety of activities like drinking, cooking, cleaning, and washing, to mention a few.

Numerous species live in water as well. Agriculture uses a significant portion of the water on Earth. It is primarily used to irrigate farms to maintain soil fertility and provide sufficient water for the crops. It is also used for raising animals. There is a lot of water in our world. As a result, all the needs mentioned earlier have been met for centuries.

200 Words Essay On Water Is Life

On Earth, there is an abundance of water. Both above and below the surface of the Earth, it exists. Rivers, ponds, seas, and oceans are just a few of the water bodies found on the surface of the Earth. Due to the sun's intense heat, the surface water evaporates. It moves through the atmosphere in the form of clouds that eventually break and fall as rain on the surface of the Earth. As a result, the water cycle, a constant natural process, replenishes the water that evaporates. This keeps the ecosystem in good shape and makes it worthwhile to live on our planet.

Usage Of Water

Agriculture, business, manufacturing, and families all require water. The quantity of water used in each sector will vary depending on the region of the world you reside. Water use significantly greatly between nations as well. Since it is frequently employed throughout some stages of the production process, water is also used in industry and manufacturing. Water is used to transport, process, chill, and dilute items.

Water can be used in large quantities during resource extraction or mining to remove minerals or other materials from the earth. Water is used in power plants to cool down hot machinery. It offers a venue for leisure activities like swimming, rowing, and water skiing. Water is also used to put out fires in case of emergencies.

500 Words Essay On Water Is Life

Water is necessary for our survival as well as for a healthy and happy life. It's time for everyone to wake up and understand how important water conservation is. In other words, the human species couldn't survive in a world without water. All plants and animals fall under this same category. In fact, without water, the entire planet will suffer. To gather rainwater, we must also employ the rainwater harvesting technique. In this way, we can conserve water.

Uses Of Water By Humans, Plants And Animals

Water has many purposes for humans.

Water consumption is essential for the survival of all living things. So, drinking water is one of its primary functions. Cooking also involves the usage of water.

Without using water, it is impossible to clean a home, workplace, car, piece of machinery, or anything else for that matter. Every cleaning task calls for water. Additionally, water is needed for washing dishes, laundry, and other items.

Agriculture uses a significant portion of the water on Earth. It is primarily used to irrigate farms in order to maintain soil fertility and provide sufficient water for the crops. It is also used for raising animals. Water is used in industries for several reasons. Water is used for various product manufacturing processes. It is utilised in the processing, manufacturing, and transporting many different items. The pulp and paper industry and the engineering sector are examples of businesses requiring a lot of water.

The Biological Need For Water

By serving as a solvent, water is an essential component of the majority of biological activities. Food is absorbed into our bodies as solutions using water as the solvent. Additionally, a lot of waste materials are eliminated as solutions through sweat and urine. Our body temperature is regulated by water. We consume a lot of water when it's hot outside. This keeps our body temperature constant. Additionally, sweat contains water that evaporates from our body's surface.

My Experience

I was on a beach vacation with my family, and we spent most of our days swimming in the ocean and playing in the waves. One day, we decided to rent a boat and snorkelling in a nearby coral reef. The water was crystal clear, and the colours of the fish and coral were so vibrant and beautiful. After snorkelling, we stopped at a small beachside restaurant for lunch, where we enjoyed fresh seafood and cold drinks while watching the waves roll in. It was a memorable day, and I will always cherish the time I spent in the water on that trip. This trip reminded me that one of my best memories was only possible because water exists. It showed me the life that water holds below land, like coral reefs and also how beautiful animals exist, like turtles.

So, to summarise, water is necessary for plants, humans and animals. Water makes Earth the only planet capable of supporting life. One of the most important resources we have on the earth is this all-purpose solvent. Water is essential to life, and we cannot exist without it. After all, it covers about 70% of the planet.

Aquatic ecosystems and global climate change.

Aquatic ecosystems are critical components of the global environment. In addition to being essential contributors to biodiversity and ecological productivity, they also provide a variety of services for human populations, including water for drinking and irrigation, recreational opportunities, and habitat for economically important fisheries. However, aquatic systems have been increasingly threatened, directly and indirectly, by human activities. In addition to the challenges posed by land-use change, environmental pollution, and water diversion, aquatic systems are expected to soon begin experiencing the added stress of global climate change.

“Aquatic Ecosystems and Global Climate Change” is the seventh in a series of reports examining the potential impacts of climate change on the U.S. environment. It details the likely impacts of climate change over the next century on U.S. aquatic ecosystems. Report authors, Drs. N. LeRoy Poff, Mark Brinson, and John Day, Jr. find:

• Increases in water temperatures as a result of climate change will alter fundamental ecological processes and the geographic distribution of aquatic species. Such impacts may be ameliorated if species attempt to adapt by migrating to suitable habitat. However, human alteration of potential migratory corridors may limit the ability of species to relocate, increasing the likelihood of species extinction and loss of biodiversity.
• Changes in seasonal patterns of precipitation and runoff will alter hydrologic characteristics of aquatic systems, affecting species composition and ecosystem productivity. Populations of aquatic organisms are sensitive to changes in the frequency, duration, and timing of extreme precipitation events, such as floods or droughts. Changes in the seasonal timing of snowmelt will alter stream flows, potentially interfering with the reproduction of many aquatic species.
• Climate change is likely to further stress sensitive freshwater and coastal wetlands, which are already adversely affected by a variety of other human impacts, such as altered flow regimes and deterioration of water quality. Wetlands are a critical habitat for many species that are poorly adapted for other environmental conditions and serve as important components of coastal and marine fisheries.
• Aquatic ecosystems have a limited ability to adapt to climate change. Reducing the likelihood of significant impacts to these systems will be critically dependent on human activities that reduce other sources of ecosystem stress and enhance adaptive capacity. These include maintaining riparian forests, reducing nutrient loading, restoring damaged ecosystems, minimizing groundwater withdrawal, and strategically placing any new reservoirs to minimize adverse effects.

The authors and the Center gratefully acknowledge the input of Drs. Virginia Burkett, Judy Meyer, Elizabeth Strange, and Alan Covich on this report. The Center would also like to thank Joel Smith of Stratus Consulting for his assistance in the management of this Environmental Impacts Series.

Executive Summary

Climate change of the magnitude projected for the United States over the next 100 years will cause significant changes to temperature regimes and precipitation patterns across the United States. Such alterations in climate pose serious risks for inland freshwater ecosystems (lakes, streams, rivers, wetlands) and coastal wetlands, and they may adversely affect numerous critical services they provide to human populations.

The geographic ranges of many aquatic and wetland species are determined by temperature. Average global surface temperatures are projected to increase by 1.5 to 5.8oC by 2100 (Houghton et al., 2001), but increases may be higher in the United States (Wigley, 1999). Projected increases in mean temperature in the United States are expected to greatly disrupt present patterns of plant and animal distributions in freshwater ecosystems and coastal wetlands. For example, cold-water fish like trout and salmon are projected to disappear from large portions of their current geographic range in the continental United States, when warming causes water temperature to exceed their thermal tolerance limits. Species that are isolated in habitats near thermal tolerance limits (like fish in Great Plains streams) or that occupy rare and vulnerable habitats (like alpine wetlands) may become extinct in the United States. In contrast, many fish species that prefer warmer water, such as largemouth bass and carp, will potentially expand their ranges in the United States and Canada as surface waters warm.

The productivity of inland freshwater and coastal wetland ecosystems also will be significantly altered by increases in water temperatures. Warmer waters are naturally more productive, but the particular species that flourish may be undesirable or even harmful. For example, the blooms of “nuisance” algae that occur in many lakes during warm, nutrient-rich periods can be expected to increase in frequency in the future. Large fish predators that require cool water may be lost from smaller lakes as surface water temperatures warm, and this may indirectly cause more blooms of nuisance algae, which can reduce water quality and pose potential health problems.

Warming in Alaska is expected to melt permafrost areas, allowing shallow summer groundwater tables to drop; the subsequent drying of wetlands will increase the risk of catastrophic peat fires and the release of vast quantities of carbon dioxide (CO2) and possibly methane into the atmosphere.

In addition to its independent effects, temperature changes will act synergistically with changes in the seasonal timing of runoff to freshwater and coastal systems. In broad terms, water quality will probably decline greatly, owing to expected summertime reductions in runoff and elevated temperatures. These effects will carry over to aquatic species because the life cycles of many are tied closely to the availability and seasonal timing of water from precipitation and runoff. In addition, the loss of winter snowpack will greatly reduce a major source of groundwater recharge and summer runoff, resulting in a potentially significant lowering of water levels in streams, rivers, lakes, and wetlands during the growing season.

The following summarizes the current understanding regarding the potential impacts of climate change on U.S. aquatic ecosystems:

1.   Aquatic and wetland ecosystems are very vulnerable to climate change. The metabolic rates of organisms and the overall productivity of ecosystems are directly regulated by temperature.  Projected increases in temperature are expected to disrupt present patterns of plant and animal distribution in aquatic ecosystems. Changes in precipitation and runoff modify the amount and quality of habitat for aquatic organisms, and thus, they indirectly influence ecosystem productivity and diversity.

2.   Increases in water temperature will cause a shift in the thermal suitability of aquatic habitats for resident species.  The success with which species can move across the landscape will depend on dispersal corridors, which vary regionally but are generally restricted by human activities. Fish in lowland streams and rivers that lack northward connections, and species that require cool water (e.g., trout and salmon), are likely to be the most severely affected. Some species will expand their ranges in the United States.

3.   Seasonal shifts in stream runoff will have significant negative effects on many aquatic ecosystems.  Streams, rivers, wetlands, and lakes in the western mountains and northern Plains are most likely to be affected, because these systems are strongly influenced by spring snowmelt and warming will cause runoff to occur earlier in winter months.

4.   Wetland loss in boreal regions of Alaska and Canada is likely to result in additional releases of CO2 into the atmosphere.  Models and empirical studies suggest that global warming will cause the melting of permafrost in northern wetlands. The subsequent drying of these boreal peatlands will cause the organic carbon stored in peat to be released to the atmosphere as CO2 and possibly methane.

5.   Coastal wetlands are particularly vulnerable to sea-level rise associated with increasing global temperatures.  Inundation of coastal wetlands by rising sea levels threatens wetland plants. For many of these systems to persist, a continued input of suspended sediment from inflowing streams and rivers is required to allow for soil accretion.

6.   Most specific ecological responses to climate change cannot be predicted, because new combinations of native and non-native species will interact in novel situations. Such novel interactions may compromise the reliability with which ecosystem goods and services are provided by aquatic and wetland ecosystems.

7.   Increased water temperatures and seasonally reduced streamflows will alter many ecosystem processes with potential direct societal costs.  For example, warmer waters, in combination with high nutrient runoff, are likely to increase the frequency and extent of nuisance algal blooms, thereby reducing water quality and posing potential health problems.

8.   The manner in which humans adapt to a changing climate will greatly influence the future status of inland freshwater and coastal wetland ecosystems.  Minimizing the adverse impacts of human activities through policies that promote more science-based management of aquatic resources is the most successful path to continued health and sustainability of these ecosystems. Management priorities should include providing aquatic resources with adequate water quality and amounts at appropriate times, reducing nutrient loads, and limiting the spread of exotic species.

Overall, these conclusions indicate climate change is a significant threat to the species composition and function of aquatic ecosystems in the United States. However, critical uncertainties exist regarding the manner in which specific species and whole ecosystems will respond to climate change. These arise both from uncertainties about how regional climate will change and how complex ecological systems will respond. Indeed, as climate change alters ecosystem productivity and species composition, many unforeseen ecological changes are expected that may threaten the goods and services these systems provide to humans.

Importance of Water Essay for Students and Children

500+ words essay on importance of water.

Water is the basic necessity for the functioning of all life forms that exist on earth . It is safe to say that water is the reason behind earth being the only planet to support life. This universal solvent is one of the major resources we have on this planet . It is impossible for life to function without water. After all, it makes for almost 70% of the earth.

However, despite its vast abundance, water is very much limited. It is a non-renewable resource . In addition, we need to realize the fact that although there is an abundance of water, not all of it is safe to consume. We derive some very essential uses from the water on a daily basis.

Significance of water

If we talk about our personal lives, water is the foundation of our existence. The human body needs water for the day to day survival. We may be able to survive without any food for a whole week but without water, we won’t even survive for 3 days. Moreover, our body itself comprises of 70% water. This, in turn, helps our body to function normally.

Thus, the lack of sufficient water or consumption of contaminated water can cause serious health problems for humans. Therefore, the amount and quality of water which we consume is essential for our physical health plus fitness.

Further, our daily activities are incomplete without water. Whether we talk about getting up in the morning to brush or cooking our food, it is equally important. This domestic use of water makes us very dependent on this transparent chemical.

In addition, on a large scale, the industries consume a lot of water. They need water for almost every step of their process. It essential for the production of the goods we use every day.

If we look beyond human uses, we will realize how water plays a major role in every living beings life. It is the home of aquatic animals. From a tiny insect to a whale, every organism needs water to survive.

Therefore, we see how not only human beings but plants and animals too require water. The earth depends on water to function. We cannot be selfish and use it up for our uses without caring about the environment.

A world without water

Water is not only required for our survival but for a healthy and happy life as well. Everyone has seen the scenario of water-deprived countries like Africa, where citizens are leading a miserable life. It is time for everyone to wake up and realize the urgency of conserving water.

In other words, a world without water would make the human race impossible to last. The same can be said for all the animals and plants. In fact, the whole earth will suffer without water.

Firstly, the greenery will soon diminish. When earth won’t get water, all the vegetation will die and turn into barren land. The occurrence of different seasons will soon cease. The earth will be caught in one big endless summer.

Furthermore, the home of aquatic animals will be taken from them. That means no fishes and whales for us to see. Most importantly, all forms of living organisms will go extinct if we do not conserve water right away.

In conclusion, unnecessary usage of water must be stopped at once. Every single person must work to conserve water and restore the balance. If not, we all know what the consequences are going to be.

The ocean is downstream of everything, so all of our actions, no matter where we live, affect the ocean and the marine life it holds. Those who live right on the coastline will have the most direct impact on the ocean, but even if you live far inland, there are many things you can do that will help marine life.

Eat Eco-Friendly Fish

Our food choices have a significant impact on the environment—from the actual items we eat to the way they are harvested, processed, and shipped. Going vegan is better for the environment, but you can take small steps in the right direction by eating eco-friendly fish and eating locally as much as possible. If you eat seafood, eat fish that is harvested sustainably, which means eating species that have a healthy population, and whose harvest minimizes bycatch and impacts on the environment.

Limit Your Use of Plastics, Disposables and Single-Use Projects

Have you heard of the Great Pacific Garbage Patch ? That is a name coined to describe the vast amounts of plastic bits and other marine debris floating in the North Pacific Subtropical Gyre, one of five major ocean gyres in the world. Sadly, all the gyres seem to have their garbage patch.

Plastic stays around for hundreds of years can be a hazard to wildlife and leaches toxins into the environment. Stop using so much plastic. Buy things with less packaging, don't use disposable items and use reusable bags instead of plastic ones wherever possible.

Stop the Problem of Ocean Acidification

Global warming has been a hot topic in the ocean world, and it is because of ocean acidification , known as 'the other global warming problem.' As the acidity of the oceans increases, it will have devastating impacts on marine life, including plankton , corals and shellfish, and the animals that eat them.

But you can do something about this problem right now. Reduce global warming by taking simple steps that will likely save money in the long run: drive less, walk more, use less electricity and water—you know the drill. Lessening your "​carbon footprint" will help marine life miles from your home. The idea of an acidic ocean is scary, but we can bring the oceans to a more healthy state with some easy changes in our behavior.

Be Energy-Efficient

Along with the tip above, reduce your energy consumption and carbon output wherever possible. This includes simple things like turning off the lights or TV when you're not in a room and driving in a way that increases your fuel efficiency. As Amy, an 11-year old reader said, "It might sound strange, but being energy efficient helps the Arctic marine mammals and fish because the less energy you use, the less our climate heats up—then the ice won't melt."

Participate in a Cleanup

Trash in the environment can be hazardous to marine life, and people too! Help clean up a local beach, park or roadway and pick up that litter before it gets into the marine environment. Even trash hundreds of miles from the ocean can eventually float or blow into the ocean. The  International Coastal Cleanup  is one way to get involved. That is a cleanup that occurs each September. You can also contact your local coastal zone management office or department of environmental protection to see if they organize any cleanups.

Never Release Balloons

Balloons may look pretty when you release them, but they are a danger to wildlife such as sea turtles, who can swallow them accidentally, mistake them for food, or get tangled up in their strings. After your party, pop the balloons and throw them in the trash instead of releasing them.

Dispose of Fishing Line Responsibly

Monofilament fishing line takes about 600 years to degrade. If left in the ocean, it can provide an entangling web that threatens whales, pinnipeds and fish (including the fish people like to catch and eat). Never discard your fishing line into the water. Dispose of it responsibly by ​ recycling it if you can, or into the garbage.

View Marine Life Responsibly

If you're going to be viewing marine life, take steps to do so responsibly. Watch marine life from the shore by going tide pooling . Take steps to plan a whale watching, diving trip or other excursions with a responsible operator. Think twice about "swim with dolphins " programs, which may not be suitable for dolphins and could even be harmful to people.

Volunteer or Work With Marine Life

Maybe you work with marine life already or are studying to become a marine biologist . Even if working with marine life isn't your career path, you can volunteer. If you live near the coast, volunteer opportunities may be easy to find. If not, you can volunteer on field expeditions such as those offered by Earthwatch as Debbie, our guide to ​ insects , has done, where she learned about sea turtles , wetlands, and giant clams!

Buy Ocean-Friendly Gifts

Give a gift that will help marine life. Memberships and honorary donations to non-profit organizations that protect marine life can be a great gift. How about a basket of environmentally-friendly bath or cleaning products, or a gift certificate for a whale watch or snorkeling trip? And when you wrap your gift - be creative and use something that can be re-used, like a beach towel, dish towel, basket or gift bag.

Essay on Aquatic Animals

150 words essay on aquatic animals.

Aquatic animals are those that live inside the water. Aquatic lives are different than normal terrestrial lives. Aquatic species breathe inside the water with the help of gills. Although they too need oxygen like us the medium is different. We inhale oxygen from the air as they inhale oxygen from water.

These aquatic animals are specially characterized as the ones who don’t get close contact with the world outside water. Our land is surrounded by water but for Aquatic animals, water is their world. Water is a world in itself in which both animals and plants live.

Fish is one good example of aquatic animals. The aquatic animals live in the sea, ponds, lakes, rivers, etc. but water is their permanent house. It can be saline, still, or fresh.

But we human for our own selfish mean keep on containing their homes with dirty oil-spills and garbage. This makes their life a living hell. Increasing water contamination and human interference in their habitats put thousands of aquatic species at grave risk of extinction and endangerment.

• As a template for you assignment

Problem Statement

Background of the issue, work through an issue or work around an issue, political, economic, societal, and environmental consequences of the pathways, works cited.

Due to the increase of motor boating in public freshwater lakes of Indiana, environmental degradation has risen in the area. There seems to be no substantive laws and regulations to curb the rise of engine propelled boats. The following goals (targets) are important in order to fix the apparent problem.

• Indiana ought to reduce the emissions of the motor boats and other recreational equipments that endanger aquatic life of natural rivers and lakes.
• Improvement of partnership relations between private and public organizations to enhance environmental custodianship is a desirable condition.
• Rehabilitation of various freshwater lakes in order to conserve the marine ecology is important for the area.

To achieve the goal of reducing emissions that endanger the aquatic life of freshwater lakes and rivers in Indiana, various pathways are crucial. They include:

• Agitating for enactment of laws that encourage ecotourism and limit the amount of harmful emissions by high-speed motor boats and other equipments of recreation is a major pathway.
• Identifying potential eco-zones in shallow lakes is a pathway that will deter boats from visiting the areas.
• Active participation by all stakeholders and community of Indiana should serve as a pathway that will enhance responsiveness of people towards the endangered rivers and shallow lakes.

According to Hill, technology has played a significant role of supporting tourism and recreation (33). The demand for motor boats has risen across the United States and the entire world. In Indiana, the number of registered and unregistered high-speed boats has tripled in the last three decades. In 2010, Indiana had a high number of registered motor boats that surpassed 280,000 (Seba 71).

This was a sharp increase of 29% from 2000 (Baromey 31). Consequently, high-speed motor boats have led to a form of recreation that is harmful to the environment. While it is imperative to underscore the role of technology in social and economic development, it is agreeable that the effects of motor boating in shallow lakes of Indiana are apparent and detrimental.

At the outset, Hill argues that high-speed boats are detrimental to aquatic environments and near-shore ecologies (45). The rationale is that over 60% of motor boats that operated in 2011 emitted harmful compounds and greenhouse gases owing to their consumption of fossil fuels to propel their engines (Seba 3).

High-speed motor boating leads to incidences of noise pollution, fossil fuel emissions and degradation of shorelines (Honey 39). This does not only affect the life of animals living in freshwater lakes and rivers but also the people utilizing the recreational facilities.

Hill points out that the question of whether or not motor boating is detrimental to aquatic life requires various perspectives and point of views (46). It is important to note that motor boating has not only increased the utilization of recreational facilities but is a major source of revenues for public institutions. In fact, US authorities recognize the role of motor boating in the economy and tourism (Zieman 134).

Nonetheless, new laws have emerged to enhance environmental custodianship in many parts of the country. This is not the case in Indiana. Current laws in Indiana that aim at regulating high-speed boating have not achieved their goals (Honey 39). In particular, Indiana’s laws do not classify specific regions within freshwater lakes according to their vulnerability and susceptibility to environmental degradation (Rodgers and Smith 140).

It is therefore difficult for motor boaters to comprehend the actual impacts of boating on shallow lakes within the region. To that end, it is essential for the regulatory authorities to enact laws that promote ecotourism.

Due to the importance of technology in enhancing reactionary activities, ecotourism has emerged as a major pathway through which Indiana can reduce the amount of fossil fuel emissions by the motor boats (Baromey 61). In fact, the concept of ecotourism advocates for a specific form of leisure that takes into account the environmental concerns raised by societies (Rodgers and Smith 143).

It is sensitive to the environment and it advances the notion that environment is a central aspect of tourism. For instance, ecotourism does not advocate for high-speed boating in shallow lakes (Zieman 135). To that end, motor boating is only possible in deep lakes and rivers in order to avoid the apparent and negative effects of high-speed boating.

It is important to mention that many sectors of tourism have embraced the concept of ecotourism in order to conserve and preserve the natural environment (Seba 72). This has enabled various public institutions to remain profitable without endangering the environment.

In addition, the concept of ecotourism has demystified the notion that regulation of motor boating activities in shallow lakes will eventually reduce revenues for the stakeholders. According to ecotourism statistics, over 79% of countries and institutions that have adopted ecotourism practices have reported increments in their profit margins over time (Seba 73).

Working through an issue involves unraveling causative factors and addressing them continuously (Buckley 63). It also involves the ability to understand the issue from firsthand experience. Active participation by all stakeholders is a central aspect of working through an issue. Every member of the society plays an important role of ensuring that the issue is addressed amicably.

While proponents of the process say that it lead to the achievement of anticipated outcomes, opponents point out that working around an issue is the best way to address a situation. In fact, they argue that working through an issue is time consuming and may require more resources than other conventional ways of resolving problems (Seba 79). Working around a problem is a subjective way of identifying and resolving problems.

The problem solver identifies the issue and recommends ways to resolve it. As such, working around the problem does not always yield results that are desirable by the entire society.

It is important to mention that I prefer working through a problem as opposed to working around an issue. The rationale is that it involves all stakeholders and ensures that the problem is monitored overtime (Seba 85). This does not only enhance problem solution but also ensures that the problem does not occur in the future.

In addition, working through a problem is an objective way of resolving problems acceptably (Buckley 106). It has the goodwill of all stakeholders and involves almost all interested parties. For instance, all stakeholders will play a role in an effort to reduce emission of motor boats in Indiana.

Various pathways will have political, economic, societal and economic consequences. At the outset, agitating for enactment of laws and regulations to guide motor boating in Indiana may have various consequences. Due to the sensitivity of the issue, major motor boat manufacturers may lobby various political actors to impede the enactment of new laws.

Nonetheless, adoption of eco-friendly laws will guarantee the society of sustainable recreational facilities. This in turn will spur economic activities associated with tourism in the entire city of Indiana (Buckley 101). Over and above, passage of new laws that aim at protecting and preserving natural lakes and rivers will have a positive impact on the environment.

The second pathway involves mapping and identifying eco-zones within the rivers and shallow lakes of Indiana. This will result to a boost in environmental conservation and enhance economic sustainability of Indiana’s tourism sector. Undoubtedly, mapping and identifying eco-zones may lead to overcrowding in some areas where motor boating will persist.

This may predispose the society to the risk of high concentration of pollutants in some specific areas. Finally, the third pathway entails rehabilitating the endangered freshwater lakes. This is possible by enhancing active participation and partnership of all stakeholders. Politically, the pathway will provide a platform where all stakeholders will discuss and contribute towards addressing the issue of motor boating.

It will also encourage the growth of positive partnership between political and social institutions. Moreover, the society will play a significant role in identifying the appropriate solution. Consequently, public awareness on the problem of motor boating will increase since all societal members are active participants in the entire process (Buckley 101).

Finally, involvement of major partners and stakeholders will contribute towards sustainable recreational practices. This will not only benefit the community but also ensure that Indiana’s freshwater lakes and rivers begin to support marine ecology once again.

The Essential Role of Water’s Specific Weight in Science and Engineering

This essay about the specific weight of water explains its importance across various scientific and engineering disciplines. It discusses how this property, defined as weight per unit volume, is crucial for designing structures like dams and irrigation systems, understanding fluid dynamics and hydrology, and predicting weather patterns. The essay highlights the wide-ranging applications and significance of water’s specific weight in practical and theoretical contexts.

How it works

Water, an essential component for life on Earth, possesses numerous properties that are pivotal to various scientific and engineering fields. Among these properties, the specific weight of water stands out due to its importance in practical applications within hydraulic engineering, environmental science, and beyond.

The specific weight of water, expressed in newtons per cubic meter (N/m³) or pounds per cubic foot (lb/ft³), is approximately 9.81 kN/m³ or 62.4 lb/ft³ under standard conditions (4°C and 1 atmosphere of pressure). This value is derived by multiplying water’s density, which is roughly 1000 kg/m³, with the gravitational acceleration of about 9.

81 m/s². These consistent values under standard conditions make water a reliable reference substance in scientific and engineering calculations.

In environmental engineering, a thorough understanding of the specific weight of water is critical for designing and analyzing structures such as dams, reservoirs, and water supply systems. For instance, determining the water pressure exerted on a dam directly depends on water’s specific weight. Engineers must account for this pressure to ensure that the dam can withstand these forces, thereby preventing structural failures and ensuring public safety.

In fluid dynamics, which examines the movement of fluids in various environments, the specific weight of water plays a vital role. Accurate knowledge of water’s specific weight is essential for understanding water flow and sediment transport in rivers and streams. These insights help predict erosion patterns, sediment deposition, and overall river behavior, which are crucial for maintaining navigable waterways and protecting ecosystems.

Meteorology, the science that studies weather and climate, heavily relies on water’s specific weight. Atmospheric scientists use this property to model the behavior of water vapor in the atmosphere, which is a key component in weather prediction and climate studies. Cloud formation, precipitation, and storm intensity are all influenced by the specific weight of water vapor, underscoring its importance in forecasting weather phenomena.

In hydrology, which focuses on the distribution and movement of water on Earth, the specific weight of water is fundamental for water balance studies and flood risk assessments. Hydrologists examine how water moves through different media such as soil, rock, and artificial channels, requiring precise measurements of water’s specific weight to predict its behavior under various conditions. This knowledge is vital for effective water resource management and disaster preparedness, ensuring communities are resilient against water-related hazards.

The agricultural sector also benefits from a deep understanding of water’s specific weight. Irrigation systems, which are essential for crop production in many regions, depend on accurate calculations of water flow and pressure. By comprehending water’s specific weight, agricultural engineers can design efficient irrigation systems that deliver the optimal amount of water to crops, promoting growth and conserving water resources.

In industry, particularly in the design of hydraulic machines such as turbines and pumps, water’s specific weight is fundamental. These machines rely on water’s properties to operate efficiently, and precise knowledge of water’s specific weight ensures they function correctly. For example, hydraulic turbines, which convert the energy of flowing water into mechanical energy, require accurate calculations of water pressure and flow to maximize efficiency and output.

In conclusion, the specific weight of water is a fundamental property with extensive implications across many scientific and engineering disciplines. From environmental engineering and fluid dynamics to meteorology and agriculture, understanding and accurately measuring water’s specific weight is crucial for designing systems, predicting natural phenomena, and managing resources effectively. This property is a cornerstone of numerous practical applications and scientific investigations, highlighting the indispensable role of water in our world.
