Our planet is composed of 70% water and 30% of land. Our body is also composed of 2/3 of water. In other words life without water is INPOSIBLE.Imagine what would happen if amount of water in nature would be drastically reduced? I believe we all know the answer and the consequences. The entire flora, fauna and the entire human being will die slowly. Now a day, we have a lot of amount of water in our planet but that is a big paradox because a big part from that water is polluted. Basically living the life without water or with polluted water is the same. Just for example if we have a glass full of water, and if someone put poison in that glass what would happen? The answer is completely the same but in this case the poison was added into the glass by the human being which actually gives us a clear picture of what is exactly happening around us. In other words people are destroying the planet and I think that if this process of self destruction continuous life on the earth is hopeless. However water pollution must be stooped because the water is more important than anything. We can survive without oil or gold but we can’t survive without water. We need water for everything. The Greek philosopher Plato said: ”Water is something most needed for sustain life, and that easily destroyed. It is therefore a need protective law" . His statement is not lost actually. Even Plato in 2500 B.C was writing about the water pollution and how we influence over our life. If we like to stop the water pollution, we must know the sources of the pollution. Water pollution

“Water pollution occurs when a body of water is affected, in a bad way, by the addition of large amounts of a material. That material might be oil, garbage, animal wastes, fertilisers and other chemicals, sewage or litter.” When water can’t perform its basic function, we say that it is contaminated. Contamination of the water can be dividing in three parts: chemical, biological and human contamination. Biological and chemical contamination pollutes the water naturally, while human contamination is result of people’s behavior and their errors. Water is not used only for drinking but it is our application in everyday activities. Water pollution can be directly, by direct discharge of harmful substances in the water or also known as point pollution and indirectly trough changes in the environment, known as nonpoint pollution. An example of this type of water pollution is when fertilizer from the fields is done in a stream of rain, in the form of a circle which in turn affects aquatic life. Most of the pollution in rivers and lakes comes from this source of pollution because it is very difficult to regulate the indirect pollution. Most of the sources contain nutrients such as nitrates and phosphates. Nutrients stimulate the process of growing on the aquatic plants and algae. The abnormal growing of these plants affects the respiration ability of the fish and other invertebrates in the water. Another type of water pollution is eutrophication. We all have been in some river or lake where there are lots of death algae, which make the water to become more polluted. This process or situation, when algae grows rapidly and water has lack amount of oxygen is known as – eutrophication. In spring and fall the body of the water can deal with those amounts of eutrophication, because than is developing the natural cycles of this type of pollution. The death algae go on the bottom of the water, where they decompose, using the oxygen from the water. This process makes big damage, because with depleted oxygen the lake or rivers become shallower or through the time it can totally dries up. ” In the summer of 1971 at the Chicago South Water Filtration Plant on the coast of Lake Michigan, the filters were clogged with so many algae it had to be removed by hand. In the winter the turbidity(sediment in the water) was so high that the water wasn't drinkable.” From this we can see that when...
