WATER POLLUTION
Water pollution is very serious in the world. These pollution are diffused into the environment. When water moves across and through the land, it wiuld carr away natural and human-made pollutants. and keep them into the lakes, rivers, ocean and the underground water. That make the water lost it's pure quality.
1. Ocean pollution--- A plenty of factories had polluted ocean by the untreated sewage. These actions would effect the biologic cycle in the ocean.
2. River pollution--- There are several sources of water pollution which reduce river water quality. For example, Industry and agriculture discharge water and pollutants. That made rivers were polluted. Also it effected people's health.
3. Lake pollution--- Due to these pollutants were flewed from the rivers. And they sank down in the lakes. These pollutants would produce chemism in the bottom of the lake. The product would pollute the water, and effected the fishes which lived in the lake.
Many causes of pollution including sewage and fertilizers contain nutrients such as nitrates and phosphates. In excess levels, nutrients over stimulate the growth of aquatic plants and algae. Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters. This, in turn, proves very harmful to aquatic organisms as it affects the respiration ability or fish and other invertebrates that reside in water. Pollution is also caused when silt and other suspended solids, such as soil, washoff plowed fields, construction and logging sites, urban areas, and eroded river banks when it rains. Under natural conditions, lakes, rivers, and other water bodies undergo Eutrophication, an aging process that slowly fills in the water body with sediment and organic matter. When these sediments enter various bodies of water, fish respirationbecomes impaired, plant productivity and water depth become reduced, and aquatic organisms and their environments become suffocated. Pollution in the form of organic material enters waterways in many different forms as sewage, as leaves and grass clippings, or as runoff from livestock feedlots and pastures. When natural bacteria and protozoan in the water break down this organic material, they begin to use up the oxygen dissolved in the water. Many types of fish and bottom-dwelling animals cannot survive when levels of dissolved oxygen drop below two to five parts per million. When this occurs, it kills aquatic organisms in large numbers which leads to disruptions in the food chain.
