As a result there are series of tests that take place in order to help ensure it is healthy enough to be used.
Soil pollution can be the result of run off from a body of water that has been contaminated. Eventually that water has to come into contact with land and then it seeps into the soil. This can prevent crops from growing as well as plants, flowers, and trees. Without these items we then have food supply problems. We also increase air pollution because the plants, flowers, and trees remove carbon monoxide from the air we breathe.
Most of the time soil pollution is the result of human error or human negligence. There are storage tanks that can be placed underground with various types of chemicals in them. If they explode or they leak then what is in them is free to flow underground in the soil. It often destroys all that is in its path which we prevent anything from being able to grow there...
