The causes of environmental pollution largely caused by hand people. Water and soil pollution is pollution that occurs in such waters river, times, lake, ocean, ground water, and so on. While soil contamination is pollution that occurs on land in both urban and rural. Nature has the ability to restore the conditions of these pollutants
with the process of purification or purified by purification of natural soil, sand, rocks and micro-organisms that exist in nature around us. The number of very massive pollution of the human nature is not capable of making
restore conditions to normal. Quickly lose their natural ability to purify the pollution that occurs. Garbage and substances such as plastics, DDT, detergents and so on that are not environmentally friendly will increasingly exacerbate the condition destruction of nature that were increasingly worse.

For Environmental Pollution in Water and on Land:
1. Erosion and high rainfall.
2. Waste of human waste from the houses or settlements.
3. Chemicals from the home location of population, agriculture, industry, and so on.
One cause of water pollution in the most famous is the result of the use DDT chemical pest eradication. DDT is used by farmers to repel and kill pests that attack agricultural land. DDT does not only affect the pests but also other animals that exist in surrounding dah even in a place very far away due to the process flow of the chain food from one animal to other animals that accumulate DDT substance. With Therefore all the animals that exist in the food chain will be contaminated by DDT including in humans. DDT that have been entered into the body will dissolve in fat, so that our bodies will be the center of a pollutant that the day will accumulate until resulting in a more terrifying effect. Due to the biological magnification / enlargement of biological organisms caused by the use of DDT:
a. damage the living body tissue
b. cause muscle spasms, muscle fatigue and paralysis can also
c. inhibit the process of calcification of the wall in an animal egg laying so that eggs can not hatch.
d. can eventually cause cancer on the body
