Essay on Water Pollution

Water pollution has become an issue of great concern in our society. Many of today’s water ecosystems and drinking water are being polluted and destroyed as we speak. There are many types of water ecosystems such as oceans, rivers, lakes, and ponds witch provide homes to many different organisms. There are overwhelming factors that contribute to the problems of water pollution such as sewage, radioactive wastes, improper disposal of trash on land, and careless beachgoers. These are all significant problems that people do not realize until all of the damage is done. There are very few methods of controlling this pollution and more need to be developed in order to try and control these problems immediately.

The first few causes of water pollution include sewage and nutrients from fertilizers being dumped into water. This causes a problem for all the organisms because the nutrients cause the algae and water plants to grow to abnormally large sizes. This can eventually block waterways. As the wastes decompose it uses up oxygen and blocks the flow of water in natural rivers and streams. Also, as these nutrients decompose in the water, they use up oxygen which can harm all the organisms living in the environment. Fish and other organisms living in water need oxygen just as much as humans need it. Since all aquatic organisms depend on oxygen in the water, without a sufficient supply they will not be able to survive. This would be a very dangerous thing. Anything that can decrease the amount of oxygen in water can seriously damage the fish supply, since fish also depend on oxygen. A solution for this problem would be to test the water quality testing to see exactly how much oxygen is in the water to find out where the major problems areas are, then not dump any more wastes in water with low amounts of oxygen.

Pollution is also caused when silt and soil wash off of plowed fields, construction and logging sites, urban areas, and eroded river banks when it rains. Although these pollutants are organic materials, when they are added all at once they can be overwhelming and can cause a big change for the organisms that live in the environment. It is very easy for too much silt to enter the water supply, for example just having silt run off of a garden. It is a problem because it changes many different things in the local environment, which could lead to killing of water organisms, and then affect the whole food chain. For example, too much silt entering the water supply could suffocate salmon eggs . This could be a problem, because a lot of different things could be affected if this happened. If the salmon supply was damaged, it could in turn affect the whole food chain. This problem could be easily prevented by taking precautions when digging and clearing out areas around a water ecosystem.
