Water Pollution

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.
