Freshwater Habitat

An alligator dozes on a log. A heron soars overhead and lands in the reeds a safe distance away. Sploop! A frog jumps into the water while insects buzz and chirp. This freshwater habitat is a busy place!

What is Freshwater?

Rivers, creeks, lakes, ponds, and streams are all freshwater habitats. So are wetlands like swamps, which have woody plants and trees; and marshes, which have no trees but lots of grasses and reeds. Freshwater accounts for only three percent of the world’s water. (The rest is saltwater.) But despite that tiny amount, freshwater habitats are homes for more than 100,000 species of plants and animals.

More Than Fish

Fish living in freshwater habitats have plenty of company. Snails, worms , turtles, frogs , marsh birds, mollusks, alligators , beavers , otters , snakes , and many types of insects live there too. Some unusual animals, like the river dolphin and the diving bell spider, are freshwater creatures . Plants such as algae, cattails, water lilies, and aspen and willow trees help keep the water clean by using their root systems to filter pollution and excess nutrients from the water.

A Place for Water

Lakes are formed by different acts of nature. Many appeared after glaciers moved across Earth during the last ice age, between 12,000 and 1.8 million years ago, and left giant bowl-shaped hollows in the land that filled with rainwater and runoff. Others were created when Earth’s crust shifted, leaving grooves and ridges to catch water. And sometimes when a volcano erupts, all the magma flows out. If the land collapses into the empty crater, it leaves holes that can turn into huge lakes. Crater Lake in Oregon was made this way.

Rivers are created when melting snow or ice runs down mountains, following the grooves and channels of the land on the way to the sea—rivers always flow to an ocean. Wetlands, areas where the land is covered with water most of the time, often form in the land surrounding rivers that flood, or in areas where groundwater seeps up through the bedrock underneath the soil. Bedrock is made of different types of rocks like granite, sandstone and limestone. Water can seep through the cracks between these rocks, and it can dissolve limestone. Beavers can even create wetlands by building dams on rivers and streams.

Famous Freshwaters

The largest freshwater habitat in the world is the Everglades , a 1.5 million acre wetlands in southern Florida . The Amazon River in South America begins in the Andes Mountains and goes 4,000 miles (6,400 km) to the Atlantic Ocean; it flows through six countries, including Peru and Ecuador . Lake Baikal in Siberia, a region in Russia , is the world’s biggest lake. This North Asian body of water contains one-fifth of all the freshwater on the planet.

So whether you’re a hungry turtle, a pollutant-sucking plant, or a thirsty human who also likes to play in the water, freshwater habitats are vital ecosystems for our planet!

500 Words Essay on Importance of Water to Life

Introduction.

Water, the most abundant and essential compound on Earth, plays an instrumental role in sustaining life. Its importance is not limited to human beings but extends to all forms of life, including animals, plants, and microorganisms.

The Biological Importance of Water

Water is the fundamental building block of life, constituting about 60% of the human body. It facilitates essential physiological processes such as digestion, absorption, transportation of nutrients, and excretion. Moreover, it acts as a solvent for various biochemical reactions, enabling the synthesis and metabolism of vital substances.

Water also maintains body temperature through perspiration and respiration, preventing overheating during strenuous activities. Its high specific heat capacity allows it to absorb and release heat slowly, thus stabilizing the internal environment against rapid temperature changes.

Ecological Significance of Water

Water bodies serve as habitats for a diverse array of organisms. Aquatic ecosystems, including oceans, rivers, and lakes, harbor a significant portion of Earth’s biodiversity. These ecosystems are not only home to marine and freshwater species but also provide food, breeding grounds, and migration routes for many terrestrial and avian species.

Moreover, water plays a pivotal role in the Earth’s climate system. It circulates heat around the globe, moderating the climate and enabling life in various regions. Through the water cycle, it facilitates the distribution of nutrients, ensuring the fertility of soils and productivity of ecosystems.

Water in Agriculture and Industry

Agriculture, the primary source of food for humans, is heavily dependent on water. It is required for irrigation, livestock, and aquaculture. The availability and quality of water significantly influence agricultural productivity, food security, and socioeconomic stability.

Industries, too, rely extensively on water. It is used in manufacturing processes, cooling, cleaning, and as a raw material in certain products. Furthermore, water is indispensable for generating hydroelectric power, a clean and renewable source of energy.

Water Scarcity and Conservation

Despite its abundance, fresh water is a limited resource. Rapid population growth, urbanization, industrialization, and climate change have exacerbated water scarcity. This crisis poses severe threats to human health, food security, economic development, and geopolitical stability.

Therefore, sustainable water management is crucial. It involves efficient use, pollution control, watershed management, and technological innovations for water recycling and desalination. Furthermore, it requires international cooperation and policy frameworks to equitably distribute water resources and mitigate conflicts.

In conclusion, water is the lifeline of our planet. Its biological, ecological, agricultural, and industrial significance underscores the need for its conservation.

ENCYCLOPEDIC ENTRY

A habitat is a place where an organism makes its home.

Biology, Geography, Physical Geography

Loading ...

Morgan Stanley

A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal , that means everything it needs to find and gather food , select a mate, and successfully reproduce . For a plant , a good habitat must provide the right combination of light, air, water, and soil . For example, the prickly pear cactus , which is adapted for sandy soil, dry climates , and bright sunlight, grows well in desert areas like the Sonoran Desert in northwest Mexico. It would not thrive in wet, cool areas with a large amount of overcast (shady) weather, like the U.S. states of Oregon or Washington. The main components of a habitat are shelter , water, food, and space . A habitat is said to have a suitable arrangement when it has the correct amount of all of these. Sometimes, a habitat can meet some components of a suitable ar rangement , but not all. For example, a habitat for a puma could have the right amount of food (deer, porcupine, rabbits, and rodents), water (a lake , river, or spring ), and shelter ( trees or dens on the forest floor). The puma habitat would not have a suitable arrangement, however, if it lacks enough space for this large predator to establish its own territory . An animal might lose this component of habitat—space—when humans start building homes and businesses, pushing an animal into an area too small for it to survive. Space The amount of space an organism needs to thrive varies widely from species to species. For example, the common carpenter ant needs only a few square inches for an entire colony to develop tunnels, find food, and complete all the activities it needs to survive. In contrast, cougars are very solitary , territorial animals that need a large amount of space. Cougars can cover 455 square kilometers (175 square miles) of land to hunt and find a mate. A cougar could not survive in the same amount of space that a carpenter ant needs. Plants need space, too. Coast redwood trees, like the ones in Redwood National Park in the U.S. state of California, can reach more than 4.5 meters (15 feet) in diameter and 106 meters (350 feet) in height. A tree that massive would not have enough space to grow and thrive in a typical community park or yard . Space is not the same as range; the range of an animal is the part of the world it inhabits. Grassland , for example, is the habitat of the giraffe , but the animal’s range is central, eastern, and southern Africa. Food The availability of food is a crucial part of a habitat’s suitable arrangement. For example, in the northern part of the U.S. state of Minnesota, black bears eat mostly plants, like clover, dandelions, and blueberries. If there were a drought , plants would become scarce . Even though the habitat would still have space (large forest), shelter ( caves , forest floor), water (streams and lakes), and some food, it wouldn’t have enough to eat. It would no longer be a suitable arrangement. Too much food can also disrupt a habitat. Algae is a microscopic aquatic organism that makes its own food through the process of photosynthesis . Nutrients like phosphorous contribute to the spread of algae. When a freshwater habitat has a sharp increase in phosphorous, algae “blooms,” or reproduces quickly. Algae also dies very quickly, and the decaying algae produces an algal bloom . The algal bloom can discolor the water, turning it green, red, or brown. Algal blooms can also absorb oxygen from the water, destroying the habitat of organisms like fish and plants. Excess nutrients for algae can destroy the habitat’s food chain . Water Water is essential to all forms of life. Every habitat must have some form of a water supply. Some organisms need a lot of water, while others need very little. For example, dromedary camels are known for their ability to carry goods and people for long distances without needing much water. Dromedary camels, which have one hump, can travel 161 kilometers (100 miles) without a drink of water. Even with very little access to water in a hot, dry climate, dromedary camels have a suitable arrangement in northern Africa and the Arabian Peninsula. Cattails , on the other hand, are plants that grow best in wet areas, like marshes and swamps . Dense colonies of these tall, spiky plants grow directly in the mud beneath lakes, stream banks, and even neighborhood ponds . A cattail habitat’s suitable arrangement depends on water. Imagine a pond at the bottom of a dirt-covered cliff . If enough loose dirt slid down into the pond, it could fill up the pond and absorb the water, not leaving enough for the cattails to grow. Shelter An organism’s shelter protects it from predators and weather. Shelter also provides a space for eating, sleeping, hunting, and raising a family. Shelters come in many forms. A single tree, for example, can provide sheltered habitats for many different organisms. For a caterpillar , shelter might be the underside of a leaf. For a mushroom fungus , shelter might be the cool, damp area near tree roots . For a bald eagle , shelter may be a high perch to make a nest and watch for food.

Red-Eyed Tree Frog The red-eyed tree frogs habitat is in tropical areas from southern Mexico to northern South America. Although they are not endangered, their habitat is growing smaller. If their rainforest home continues to shrink, the red-eyed tree frog will not have the space it needs to survive.

Ponds and Lakes: A Journey Through the Life Aquatic

essay about water habitat

Lakes and ponds (also known as lentic systems) are a diverse set of inland freshwater habitats that exist across the globe and provide essential resources and habitats for both terrestrial and aquatic organisms. Although widely distributed and vital for many species , including humans, these habitats account for just over 3% of the Earth's surface (Downing et al . 2006). Importantly, these rare systems are increasingly threatened by the human demand for freshwater as well as human activity (Dudgeon et al . 2006). Recent evidence suggests that freshwater systems are more imperiled than marine and terrestrial ones (Sala et al . 2000, Dudgeon et al . 2006). Effective conservation and management of these systems relies on our ability to fulfill the growing human demand for freshwater while maintaining system integrity.The study of lentic systems is conducted within the field of limnology. Limnology is the study of the structural and functional interrelationships of organisms of inland waters as they are affected by their dynamic physical, chemical, and biotic environments (Wetzel 2001). Several excellent books published within the past decade provide in-depth coverage of lakes and ponds (Wetzel 2001, Brönmark & Hansson 2005, Moss 2010). Another excellent resource is the Encyclopedia of Inland Waters (2009). In this article, we present a brief overview of lentic systems and refer the reader to specific literature for more detailed information.

Physical and Chemical Structure

Size, formation, and succession.

Lentic systems vary from ephemeral ponds that fill briefly during rain events and then dry out, to permanent water bodies such as lakes (Figure 1). The world's largest freshwater lake, based on area, is Lake Superior of North America (82,100 km2) while the deepest is Baikal Lake of Asia (max depth = 1741 m; mean depth 730 m). Lakes and ponds are formed by a diversity of processes. For example, the geologic uplift of mountains can lead to depressions that fill with water to create lakes. The subsidence of land along faults between tectonic plates has lead to the formation of deep rift lakes such as the Rift Valley Lakes of eastern Africa. Lakes can also form in the crater of an inactive volcano. The movement of glaciers has been an important force in creating lakes and ponds. For example, the Laurentian Great Lakes were created following the retreat of the Laurentide ice sheet during the last ice age 10,000 years ago. Rivers also play a role in creating lakes. For example, a wide meander in a river can be cut off from the main river to form an oxbow lake . Additionally, the flood plain of a river can inundate surrounding habitats creating small ponds as floodwaters recede.

View Terms of Use

Humans also create lentic habitats. Across the world, humans have constructed impoundments and reservoirs to provide water resources for humans and livestock, generate energy, or control flooding. While large water bodies have historically received most of the attention, ponds are the numerically dominant lentic habitat (Downing et al . 2006). Ponds are generally <2 hectares in size, shallow (<3 m), and dominated by aquatic plants. Ponds have a diversity of ecological and geological origins including man-made impoundments. Moreover, due to their small size, ponds often have characteristics that are distinct from larger water bodies, which we will point out below.

Thermal stratification

Light transmission, nutrient inputs and cycling, biotic structure: lake zones and food webs, primary producers.

Primary producers are broadly divided into three groups, periphyton , phytoplankton , and macrophytes . Periphyton grows on substrates such as mud, sand, rocks, and leaf litter where it appears as a green or brown film. This is an important resource for a diversity of herbivores including macroinvertebrates (e.g., snails) and amphibian larvae. Phytoplankton is algae suspended in the water column. Phytoplankton is divided into several groups (e.g., cyanobacteria , diatoms, chrysophytes, dinoflagellates, desmids) that tend to dominate at different levels of lake productivity. Herbivores such as zooplankton are common consumers of phytoplankton. Macrophytes are generally the most visible group of primary producers in lakes and ponds (Figure 2). Macrophyte species possess a diversity of growth forms. Emergent macrophytes undergo photosynthesis above the water and are typically found close to the shoreline. As depth increases, submerged macrophytes that undergo photosynthesis under the water, dominate. Macrophytes provide resources for many herbivores as well as important refuge from predators.

Patterns in Species Richness

Threats to lentic ecosystems.

The biodiversity of freshwater habitats is increasingly threatened by human activities. Habitat loss, eutrophication, acidification, chemical contamination, global warming, and exotic species are just some of the factors that have directly or indirectly impacted lentic systems (Brönmark & Hansson 2002). Substantial progress has been made in identifying how some of these threats affect aquatic communities, and how to develop management strategies to reduce or eliminate their impacts. For example, the input of phosphorus, a limiting nutrient in lentic systems, was identified as a major contributor to lake eutrophication (Schindler 1974). Consequently, laws have been enacted to treat wastewater and reduce sewage input of phosphorus into lentic systems. Although some lentic systems have recovered, eutrophication remains a persistent problem due to agricultural intensification and other non-point pollution sources. Another challenging problem is the introduction of exotic species including plants, animals, and pathogens into lentic systems (Figure 3). In North America, for example, exotic wetland plants (e.g., purple loosestrife [ Lythrum salicaria ], Eurasian watermilfoil [ Myriophyllum spicatum ]) and animals (e.g., grass carp [ Ctenopharyngodon idella ], zebra mussel [ Dreissena polymorpha ]) can outcompete native species for nutrients or space. The introduction of the amphibian chytrid fungus ( Batrachochytrium dendrobatidis ) into Central America is implicated in the extinction of numerous amphibian species (Kilpatrick et al . 2010). While the potential negative consequences of exotic species introduction are well recognized, controlling their spread is difficult and, once established, eliminating them from communities has been difficult. Lastly, human-mediated habitat loss and alteration are increasing concerns driven by the expanding need for agricultural lands as well as development. These activities not only lead to the loss of habitat for species and vital water resources for a region, but also fragment and alter the landscape in which the remaining habitats are embedded. The combination of these threats and the scarcity of freshwater habitats make lentic systems one of the most imperiled on the planet (Sala et al . 2000, Dudgeon et al . 2006).

What are wetlands, and why are they so critical for life on Earth?

These unique ecosystems have a small footprint but play a big role in providing habitat for wildlife, and protecting us against floods and pollution

This ecosystem by many names—bogs, swamps, bayous, marshes, billabongs, fens, vernal pools, lagoons and other waterlogged fields and forests all fall under the broad wetland category . If water, salty or fresh, is present on top of or just below the soil, it’s a wetland. You’ll know you’re in a wetland when your shoe prints turn muddy and wet.

They make up just 6   percent of Earth’s surface. Despite their small footprint, wetlands have important jobs, providing fresh water and habitats, and fighting climate change.  

Wetlands were historically considered wastelands. Many have been drained and filled in with sediment to become solid ground for structures like homes, highways, and businesses. But protecting these misunderstood environments can help wildlife thrive and protect us from a changing climate.

What are wetlands?

These diverse ecosystems are found on every continent except for Antarctica.

Generally, they’re divided into two categories: coastal or inland. Coastal wetlands are a mix of fresh and saltwater, a combination called brackish water. Wetlands here look like grassy salt marshes and mangrove forests.  

A school of silversides swim through a mangrove forest.

Inland wetlands consist of vernal pools, woodland swamps, bogs , or waterlogged, grassy stretches near rivers and lakes. While many inland wetlands contain freshwater, some are salty, like this salt marsh in Nebraska that was once a prehistoric ocean. They occur as a result of rainy climates or groundwater gurgling up toward the surface. Some are seasonal, appearing only during rainy periods.

Protecting against floods and purifying water  .

Perpetually in limbo, wetlands are “ transition zones ” between dry land and water. During floods, they sponge up excess rainwater that would otherwise cause flooding and damage homes. One acre of wetland can store over one million gallons of flood water.

Since the 18th century, over 64 million acres of wetlands have been destroyed in the Upper Mississippi River Basin as a result of agricultural and urban development. The environmental loss contributed to the billion-dollar flood disaster that occurred in the region in 1993.

But wetland protection in the form of city parks and green spaces along the Charles River in Boston has prevented an estimated $17 million in potential flood damage, according to research done by the U.S. Army Corps of Engineers.  

On the coast, wetlands help buffer the onslaught of storm surge pushed onto land by powerful storms like hurricanes.  

When runoff contains pollutants like fertilizer sprayed on agriculture fields, wetlands are natural water filters that absorb these nutrients and prevent them from reaching lakes and rivers. Chemicals stuck to soil particles are slowed by wetland plants, suspended, and pollutants are locked in place by wetland plant roots.  

The Congaree Bottomland Hardwood Swamp in South Carolina filters so much pollution every year, it would take a $5 million-dollar water filtration plant to filter the same amount, according to the EPA .

Supporting life  

Well-known animal and plant species such as alligators, turtles, and snakes live in wetlands around the world. In North America, migratory birds use these habitats as pit-stops on their cross-country journeys. Of the 12 million waterfowl in the U.S., as many as two thirds reproduce in Midwestern wetlands.  

Greater flamingos at the Al Wathba Wetland Reserve.

These ecosystems are important for humans, too. Their calm waters are breeding grounds for valuable fish and shellfish species like bass and oysters. Wetlands play a role in the life cycle of 75 percent of these commercially harvested species in the U.S.  

Globally, two-thirds of all the fish we eat spend at least part of their life in a wetland. An estimated one billion people around the world depend on wetlands to support their livelihoods through activities such as fishing, rice farming, hunting, or tourism.  

Fighting climate change

Once released, most greenhouse gasses stay in the atmosphere, warming the planet. But about 26 percent is absorbed by plants growing on land. These types of ecosystems are called carbon sinks, and they absorb millions of tons of carbon every year.  

Wetlands are carbon sinks that, when destroyed, can become a major source of greenhouse gas emissions. Altogether, wetlands contain about a third of the world’s carbon , and when they’re degraded, the emissions locked in their soils are released.

Expedition team members begin morning activities along the Cubango River.

Peatlands in particular are important to conserve if we want to prevent wetlands from becoming a source of atmospheric pollution. They occupy only 3 percent of Earth’s surface, but their waterlogged soils store twice as much carbon as the world’s forests—about 30 percent of all the carbon locked in the world’s soils. To degrade them would be to set off what some scientists have described as a “ carbon bomb .”

While wetlands are increasingly being recognized as important ecosystems, draining them for development is a practice that still continues today. In the U.S. alone about 80,000 acres of wetland are lost every year. Louisiana loses about a football field’s worth of marshland every hour.

In countries like Scotland and Argentina where peatlands are common, wetlands are destroyed when peat is dug up and burned for energy.

Invasive plant and animal species can also destroy wetland habitats. Beavers and nutria , a type of invasive rodent, damage wetlands by devouring plants that hold wetland soil together.

Wetlands in court  

This year, the Supreme Court will rule on a case called Sackett v. EPA   that could have profound consequences for how wetland protection is regulated in the U.S. In 2007, the EPA stopped the Sackett family from building their home because the agency said the property included a wetland that fed a nearby lake over which they have jurisdiction. To build their home, the family had to fill the land with sediment. The Sacketts sued the EPA in 2008, claiming their property was not wet enough to constitute a wetland.

The decision will be decided based on whether the Sackett's property included a wetland that significantly affected nearby federal waters. Wetlands that are more obviously connected to rivers, lakes, and coastlines tend to have more protections than those whose connections to navigable waters are less obvious—often wetlands that are not adjacent to a body of water or are seasonal.

String bogs link small islands of coniferous forests.

Lawyers at EarthJustice, a law firm dedicated to environmental protection, say the Court’s decision could dramatically reduce how many wetlands are protected by the Clean Water Act.

What are we doing to protect them?

In 1971, world leaders met in the Iranian city of Ramsar to create a global treaty to protect wetlands—the Ramsar Convention on Wetlands . Currently, 171 countries have signed the treaty, but since it was signed into effect in 1971, more than a third of the world’s wetlands have been destroyed.  

( In the Philippines, this tropical marsh is slipping away .)

In 2021, scientists published a paper arguing that wetlands should be granted legal rights because of their role in supporting life on Earth.

Private companies are also looking at wetlands as a source for carbon offsets , which allow individuals and businesses to theoretically “offset” their carbon emissions by contributing to the conservation or restoration of ecosystems that absorb their equivalent emissions.  

Where wetlands are already destroyed, there are some ambitious projects hoping to bring them back to life.  

The swampy mangrove forests of Miami Beach were destroyed 100 years ago, but the city plans to restore this ecosystem   to limit shoreline erosion and prevent flooding. And in Louisiana, the state has an ambitious plan to allow rivers to retake their natural shape and dump river sediment into their southern marshes, helping rebuild the wetland coastline.

A report published by the Ramsar Convention says the world’s wetlands are still being lost at an alarming rate, but restoration and conservation projects offer hope that these ecosystems can be saved.

Protecting and restoring habitats to benefit freshwater biodiversity

Morgan l. piczak, denielle perry, steven j. cooke, ian harrison, silvia benitez, aaron koning, li peng, peter limbu, karen e. smokorowski, sergio salinas-rodriguez, john d. koehn, irena f. creed, environmental reviews.

Freshwater biodiversity is under great threat across the globe as evidenced by more severe declines relative to other types of ecosystems. Some of the main stressors responsible for these concerning trends is habitat fragmentation, degradation, and loss stemming from anthropogenic activities, including energy production, urbanization, agriculture, and resource extraction. Habitat protection and restoration both play an integral role in efforts to save freshwater biodiversity and associated ecosystem services from further decline. In this paper, we summarize the sources of threats associated with habitat fragmentation, degradation, and loss and then outline response options to protect and restore freshwater habitats. Specific response options are to legislate the protection of healthy and productive freshwater ecosystems, prioritize habitats for protection and restoration, enact durable protections, conserve habitat in a coordinated and integrated manner, engage in evidence-based restoration using an adaptive management approach, ensure that potential freshwater habitat alterations are mitigated or off-set, and future-proof protection and restoration actions. Such work should be done through a lens that engages and involves local community members. We identify three broad categories of obstacles that could arise during the implementation of the response options outlined: (a) scientific (e.g., inaccessible data or uncertainties), (b) institutional and management (e.g., capacity issues or differing goals across agencies), and (c) social and political (e.g., prioritizing economic development over conservation initiatives). The protection and restoration of habitats is key to Bend the Curve for freshwater biodiversity, with a comprehensive, connected, and coordinated effort of response options needed to protect intact habitats and restore fragmented, degraded, and lost habitats and the biodiversity and ecosystem services that they support.

The Global Impacts of Habitat Destruction

Habitat destruction is one of the biggest threats facing plants and animal species throughout the world. The loss of habitat has far-reaching impacts on the planet’s ability to sustain life, but even with the challenges, there is hope for the future.

Habitat destruction, defined as the elimination or alteration of the conditions necessary for animals and plants to survive, not only impacts individual species but the health of the global ecosystem.

Habitat loss is primarily, though not always, human-caused. The clearing of land for farming, grazing, mining, drilling, and urbanization impact the 80 percent of global species who call the forest home. Approximately 15 billion trees are cut down each year. According to a study about tree density published in Nature , the number of trees worldwide has decreased by 46 percent since the start of civilization. In addition to the loss of habitat, deforestation reduces the ability of forests to provide the critical benefit of absorbing carbon, which helps to mitigate the effects of climate change.

The situation is even worse in waterways, coastal areas, and the ocean. Coastal estuaries and marshes provide breeding grounds for the majority of marine species. As they, along with inland wetlands, are dredged and filled, species are less able to birth and support their young. Pollution and effluents from the land travel easily through streams and rivers to the ocean, where they impact the health of fish, birds, and marine plants. Deforestation far from shore can cause erosion that enters the water and deposits silt into the shallow marine waters, blocking the sunlight that coral reefs need to survive.

Despite the habitat loss that has occurred globally to date, there is still hope. Studies reveal that by protecting 50 percent of the land and ocean around the world, plant and animal species could thrive. Today, only 15 percent of the land and 7 percent of the ocean is protected, leaving us with a challenging yet attainable goal.

The Campaign for Nature calls upon world leaders to take action in helping to protect 30 percent of the Earth’s land and ocean by 2030, on the way to 50 percent of the planet in a natural state by 2050. This commitment represents our best opportunity to preserve the ecosystems necessary for our survival.

Do not Waste Water

While water is quite essential and yet so scarce, however, people fail to realize this fact. They waste water with little or no care for the results of this activity. There are various ways in which one can avoid wasting water . To begin with, all households must get their leaking taps checked. They should fix them immediately as every drop is precious.

Similarly, we must choose buckets instead of showers for bathing. This is a very debatable topic and it needs to be settled. Showers waste a lot of water, so people must prefer buckets. This particular habit is quite commonly found in most of the households. People do not turn off their taps while brushing their teeth and washing utensils. Always remember to keep the tap off when doing so.

In addition, encourage rainwater harvesting system in all homes. This can help conserve water like never before.

In short, water is essential for the survival of mankind. But, it is, unfortunately, being waster rapidly. Every citizen and government must come together to tackle this issue. Governments must ensure all areas get water equally. On the other hand, citizens must keep in mind to use it wisely and not waste it unnecessarily.

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.

Short Essay on Importance of Water (200 words)

Water is available in abundance on Earth. It is present on the surface of Earth as well as beneath it. The water bodies present on Earth’s surface include rivers, ponds, seas and oceans. The surface water evaporates due to the excessive heat of Sun. It is circulated in the atmosphere and forms clouds that burst and reach the Earth’s surface in the form of rain. Thus, the water that evaporates gets replenished by the natural process of water cycle which occurs continuously. This helps in maintaining the eco system and makes our planet worth living.

While Earth is filled with plenty of water, fresh water is very small part of it and its amount is only decreasing by the day. It is sad but true that due to various human activities and human negligence, the water present on Earth is getting polluted. Fresh water is getting depleted as the water bodies are being polluted due to industrial as well as domestic waste.

It is high time we must understand the importance of water in our lives and the necessity to save it. There are many simple ways in which we can avoid wastage of water such as bathing with less water, watering plants with waste water from RO, cleaning the car with a wet cloth rather than pipe, etc. We must also use the method of rain water harvesting to collect rain water. This way we can contribute our bit to save water.

Introduction.

Water is available in abundance on Earth. It is one of the main reasons which make life possible on our planet. Available from different sources, water is an essential requirement for all the living beings. It is used for various purposes by human beings. Here are some of the important uses of water.

Different Uses of Water

  • Drinking: Drinking water is vital for the survival of living beings. So, one of the main uses of water is drinking.
  • Cooking: Water is also used for the purpose of cooking. Many recipes such as lentils, rice, soups, etc require water. Besides, even the vegetables and fruits that do not require added water for preparation need to be washed thoroughly before eating/ cooking.

Why is Water Cycle Important?

Water needed for the survival of the living beings. Be it plants, animals or human beings – all three require water. While plants and animals mainly require water for the purpose of drinking or as habitat, human beings use water for several purposes. Water would have long vanished from the face of Earth if the process of water cycle hasn’t existed.

The process of water cycle involves different steps. These are evaporation, transpiration, condensation, precipitation and surface run off. Water evaporates from different sources including oceans, seas and rivers due to sun’s heat. Water vapours rise into the atmosphere. Slowly these vapours cool down and condense to form clouds.

When large amount of vapours join together, the cloud becomes heavier and falls in the form of rain. This way the water falls back on the surface of Earth. It gets accumulated in rivers, lakes, oceans, layers of rocks and soil. This completes the process of water cycle. The water collected in oceans and other water bodies once again evaporates and the entire cycle reoccurs. This is an ongoing process. Water cycle also impacts the weather condition on Earth. The cycling of water in the atmosphere regulates the weather patterns.

Important Sources of Water

Sources of water have broadly divided into two categories:

  • Surface Water: This found in rivers, lakes, streams, seas, oceans and also reservoirs. The downpour from the clouds and the melting of snow from the mountains fill the rivers and the lakes. Rivers flow continually and also meet the sea. The sea water flows into the ocean. Surface water evaporates and enables the water cycle process.
  • Ground Water: Ground water is present under the Earth’s surface. Water seeps under the land via porous rocks and soil. This water gets stored under the Earth’s surface and extracted by digging wells and also constructing tube wells.

Water cycle makes sure the lost water replenished on the planet and is available in abundance for all the living beings. If this process did not occur naturally we would not have sufficient water on our planet.

Essay on Importance of Water – An Essential Part of Our Life (500 words)

Water is an essential part of our ecological system. It is one of the main substances that make our planet fit for living. Water is essential for the growth and development of plants and animals. However we use water directly as well as indirectly for many of our needs.

Water – An Essential Part of the Human Body

Research shows that up to 60% of the human body made of water. Our lungs are around 83% water, our muscles and kidneys are 79% water, our brain and heart are 73% water, our skin contains 64% water and our bones have 31% water. Water helps in several functions of the body including blood circulation, digestion, regulating body temperature, protecting tissues and joints and also excreting waste via perspiration, defecation and urination.

Our body continually uses water to perform these functions. So, we need to provide a continuous supply of water to our body to help it function well. It is important to replenish the lost water timely.

Water – Vital for Plant Growth

Plants prepare their food by way of photosynthesis. Water forms an essential part of this process. As we water the plants, it enters their stem and moves up to their leaves. However it draws nutrients from the soil and carries them to the leaves. Photosynthesis takes place in the leaves. The water present in the leaves evaporates and exchanged for carbon dioxide.

Without proper supply of water, the plants do not get enough nutrients and photosynthesis cannot take place. As a result, the plants begin to droop and fall. Different kinds of plants require different amount of water at different times. While some plants need to watered twice a day others require water once a week while there are yet others that can go weeks without water especially during cold and moist season.

Water – Habitat for Marine Creatures

Water serves as home for the marine creatures. Wide variety of fishes, turtles, frogs, crabs and other marine creatures live in seas, oceans and rivers. These water bodies are their habitat. Most marine creatures live solely in water and cannot survive on land. They add to the biodiversity and also are an essential part of the eco system.

The increase in the level of water pollution is causing a threat to these beautiful and innocent creatures. Many species of the beautiful marine creatures have either gone extinct or endangered. Water pollution caused due to various human activities. It needs to controlled in order to provide a safe and healthy habitat for the marine creatures.

Water is vital to the survival of living beings. Even as water recycles naturally, the amount of fresh water on Earth is depleting fast. This is all because of the negligence of human beings. We use water for several purposes throughout the day. But we aren’t using it efficiently. We waste it more than we use it. This is the reason why water is decreasing at a rapid speed. It is high time we must use water wisely and limit the activities that pollute it.

Long Essay on Importance of Water (600 words)

Water is among the most essential substances on Earth. Two third of Earth covered with water; however, only a small part of it fresh water which is fit for human use. The growing pollution is polluting the fresh water too, thereby making it unfit for any kind of use. Besides, fresh water available for use often wasted during various activities. This has become a global cause of concern. It is time we should understand the importance of water and also try to save it.

Conversation of Water

In this era of growing water pollution, we need to watch out our activities. Fresh water is getting scanty mainly due to two reasons. One of these is the increasing level of water pollution caused due to industrial waste and various other human activities and the other is the continuous wastage of water by people around the world.

We must conserve water otherwise it will become difficult for us to survive on Earth in the times to come. Water is essential to maintain the ecological balance and create an atmosphere which is appropriate for us to survive. It also needed for drinking, cooking, cleaning, irrigating the fields and various other activities. We need to save water and put it to correct use.

Methods to Conserve Water

There are many ways in which we can conserve water. Several activities that we indulge in our daily lives can done differently to save water. Here is a look at these:

  • We often keep the tap on while we brush our teeth. This results in a lot of wastage of water. Turn the tap on only when you require it, else keep it off. A lot of water that goes down the drain unnecessarily will saved this way. Practice the same while washing your hands as well.
  • It is best to use bucket while bathing as a lot of water wasted while taking shower. Or you can keep a tub under the shower when you don’t require water while taking shower. This water can used for watering the plants or flushing.
  • The waste water from RO can collected in a bucket and used to water the plants or for cleaning purpose. You can also do the same with the water left after boiling potatoes, noodles and pasta. This water is hot and can very well used for cleaning oily and greasy utensils.
  • Water the plants during evening or early morning hours so that the water absorbed properly and does not get evaporated fast. This way you will require less water for watering the plants.
  • Do not make use of water to defrost food items.
  • Instead of using a pipe to wash your car, it suggested to use a bucket and wet cloth. You can also get it washed regularly from a car wash service that uses recycled water for this purpose.
  • Rainwater harvesting is a good way to store water and to put it to good use.
  • Install water efficient appliances such as low flow bathroom fixtures, sink systems, dish washers and washing machines and use them wisely to save water. For instance, make sure your washing machine and dish washer completely loaded before you turn them on.
  • Do not neglect any leakage in your kitchen, bathroom or any other part of your house. Get it fixed immediately to avoid wastage of water.
  • Using less electricity is an indirect way to save water. This is because power plants use several gallons of water.

Conservation of water must taken seriously. The government of every country should restrict activities that result in water pollution and wastage of fresh water and the citizens must provide complete support in this direction. Each one of us should realize the importance of water and take it as our responsibility to use the simple ways mentioned above to conserve water.

essay about water habitat

  • Anseriformes

The Swan is a large waterfowl in the Anatidae family. These birds are generally quite large, with long curved necks. They share a family with the smaller ducks and geese, though they are more closely related to geese than they are to ducks.

There are six different species of Swans including the mute Swan , Tundra Swan , Black Swan , Trumpeter Swan , Black-Necked Swan, and the Whooper Swan. Read on to learn about the Swan .

Black Swan

Description of the Swan

Swans are the largest members of the Anatidae family, and the largest Swan species is the Trumpeter Swan . At their largest, their wingspan grows up to 10 ft. across. They also weigh up to 30 lbs. at their largest, though most weigh around 15 lbs. or so.

These large birds also have incredibly long necks, which they often curve to rest on their backs while swimming. Some species are white, while others are black, off-white, or black and white.

Interesting Facts About the Swan

Swans are undeniably large, graceful, and imposing birds. They are beautiful and often quite territorial as well. Learn more about these unique birds below.

  • Battering Bird – A pair of nesting Swans is not something you want to contend with! Some species are more territorial and aggressive than others, but all species protect their young. These defensive birds rush at a potential threat and batter it with their wings or bite with their beaks.
  • Ugly Duckling – Baby Swans, known as “cygnets,” are not born white. Most white species of are born gray, and they become white as they age.
  • Monogamous Mates – Like many ducks and geese, Swans usually mate for life. A pair of these beautiful birds bonds strongly, and continues to mate with the same partner year after year. These birds do occasionally choose a different mate if their partner dies or they cannot produce offspring.
  • High Speeds – Though these birds drift gracefully across the surface of lakes and ponds, they are more than capable of moving quickly. While they usually swim relatively slowly, they fly incredibly fast. In fact, some species can fly up to 60 miles per hour!

Habitat of the Swan

Swans are waterfowl, and rely very heavily on water bodies in their environment. They live in a variety of environments, including lakes, ponds, slow moving rivers and streams, wetlands , marshes, and more.

When nesting, these birds usually choose sites in close proximity to water. They nest on islands, reed beds, and in dense vegetation close to the edge of the water.

Distribution of the Swan

Different species live across many different continents worldwide. Even though there are only six species of these birds, they cover a huge area of distribution combined. They live across Europe and Asia, Australia and the surrounding islands, North America, Central America, and South America. Some species are more widespread than others, though many migrate long distances.

Diet of the Swan

Swans are usually herbivores, and feed primarily on plants and plant matter. They forage both in the water and on land. While they are in the water, they dabble by flipping upside down and using their long necks to reach for aquatic vegetation. On land they graze on grasses and other plants. These birds eat a variety of underwater plants, roots, leaves, shoots, and stems.

Swan and Human Interaction

Humans interact with these graceful birds fairly frequently. Sometimes Swans live in public parks, where they are occasionally aggressive towards humans when guarding their nests or young.

Humans destroy important habitat for some species, and this can result in population decline. Human impact varies from species to species, but the IUCN lists all Swan species as Least Concern at the moment because their populations are stable.

Domestication

Humans have domesticated or semi-domesticated Mute Swans . They breed these birds for meat, feathers, and simply as pets or ornaments on lakes and ponds. Domesticated Swans are more friendly than their wild counterparts.

Does the Swan Make a Good Pet

While we have domesticated some species, that doesn’t mean they are a good choice as a pet. For you to provide a proper home, the bird must have a partner, and a large water body to swim in. No wild Swan species makes a good pet, and it is illegal to capture, harass, or kill one.

Swans on farms, in zoos, and in parks all share one common need, a large lake or pond! These birds must have somewhere to swim and forage for food, even if you feed them pelleted feed.

Pelleted foods provide all the nutrients that they need, but they still need to swim and forage as they would in the wild. These birds also form pair bonds for life, and must have a partner or mate to live with.

Behavior of the Swan

Behavior varies from species to species and bird to bird. While some species are more docile, many are quite territorial and aggressive towards humans, other birds, and virtually anything.

They spend their days drifting across the water and dabbling for food, or walking on land and picking at the grass and plants. When they are breeding, Swans become very protective of their nests, mates, and cygnets.

Reproduction of the Swan

Most of these birds are monogamous, and breed with the same partner year after year. The pair builds a large nest, usually out of grasses, reeds, small branches, and vegetation. Females lay between four and seven eggs per clutch.

Depending on the species, incubation lasts anywhere from a month to a month and a half. The cygnets stay under the watchful eye of their parents until they are about a year old.

Beliefs, Superstitions, and Phobias About the Swan

These birds are present in many different cultures, artistic renditions, and even coins! The tale, “The Ugly Duckling,” is a famous story about an “ugly” duckling that grows into a beautiful Swan.

This is just one example of Swans in human culture. It is no surprise that these birds are readily adopted into human habitation, parks, and gardens because they are incredibly beautiful and graceful.
