Essay on, water, pollution for Children and Students

The carnivores ate the herbivores and the second carnivore(Humans or birds) eat them. As the ddt moves up the food chain it intensifies and the concentration is very dense by the time it reaches the carnivores. What goes on the farm ends up in our food, one way or the other. On ranches the problem becomes the excess of excretion from the cattle.(25,000 cattle produce 300,000 gallons of waste a day) All of this urine and manure goes straight to the ground water and right back to the rivers and lakes. At least the human waste is sent to a sewage system, which does some good. This cattle waste is being sent straight to the water supply, untreated. In Oregon, tallamook bay is closed to oyster growing at certin times of the year, because of the high levels of contamination from the cattle. Where do we draw the line?

On the farms all the excess fertilizer gets into the streams and ends up in the lakes. When the fertilizer reaches the lake or stream, it cause eutrophication to occur. This means that less fish can survive and the water will go from clear to cloudy. No one wants to swim in water that you can't see your feet. Another problem farms present is the loss of soil make and sediment in rivers. The precious soil is stolen by erosion and carried off in the rivers. The lose of the soil is bad enough, but the horrible part is that along with the soil goes all of the fertilizer, pesticides and herbicide used on the fields. In other words, any chemical put on the crops to prevent animals or bugs from eating them ends up in the water we drink. In the 1960's and 1970's the pesticide ddt was heavily used. This chemical was applied on the farms and runoff took it to the lakes. The plants absorbed the ddt and then the herbivores ate the plants.

with algae. This situation is known as eutrophication, where algae growth is out of control and the water becomes oxygen depleted. There are natural cycles of eutrophication in the spring and fall, but the body of water can deal with those amounts. When excess waste is added to the water the body of water can no longer control the growth 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 much dead algae all the oxygen is depleted. Oxygen from the surface doesn't reach 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 piles upon itself and makes the lake shallower, until it totally fills in and dries. Eutrophication effects all bodies of water, great and small. In the summer of 1971 at the Chicago south Water Filtration Plant on the coast of lake michigan, the filters were clogged with so much algae it had to be removed by hand.

After taking that fact into account, one can see why the conservation and protection of our remaining water supply is so vital. Before water pollution can be stopped, the sources of the pollution must be known. The major sources of water pollution are organic pollution, agricultural pollution, runoff, toxic waste, and thermal pollution. Organic pollution is becoming more and more pressing on the environment, because of the growing population of the world.
