The major sources of piddle pollution argon organic pollution, agricultural pollution, runoff, toxic run out, and thermal pollution. constituent(a) pollution is becoming more and more pressing on the environment, because of the growing population of the world. Its a simple concept, the more bulk there are in nonpareil area, the more waste they will produce. For example, in a city there are so many people that the sewage plants and the environment cant wear care of all of the waste and function in its popular manner. The sewage plants do their best, but the secondary discharge that gets into the body of water supply supply causes great problems. The excess waste acts as a fertilizer or food source for algae and the process rate is uncontrollable. Everyone has been in a lake where there are a lot of suddenly algae on the shore and the water is clouded with algae. This situation is known as eutrophication, where algae branch is out of control and the water becomes oxygen depleted. There are natural cycles of eutrophication in the spring and fall, but the torso of water can deal with those amounts. When excess waste is added to the water the body of water can no longer control the ontogeny of the algae and the water soon becomes algae ridden and oxygen depleted.
The water becomes oxygen depleted, because the dead algae goes to the bottom and uses the oxygen in the deeper water to decompose, but if there is too often dead algae all the oxygen is depleted. Oxygen from the surface doesnt name the bottom, because the warmer water is less dense than the deeper cooler water, therefor the warmer water floats on the colder water and they never mix, much like oil and water. Soon the dead algae lots upon itself and makes the lake shallower, until it totally fills in and dries up.
