In many parts of the world, huge corporations take advantage of lenient environmental laws by dumping hazardous waste into any convenient area they chose. In the US, although we have many laws to protect the environment, most are just touching the tip of the iceberg in terms of providing complete protection. This day was sometime in autumn and was practiced at least up until the revolution of 1979. With the total human population soaring past six billion, we are having to find ways to produce more and more food from a land that is proving less and less capable of sustaining such a large population. In many areas, the more trees we cut down, the more erosion takes place.
Flooding is one of the results of erosion.
In deforested areas water has no place to go but down, and fast. During rainstorms the water flows off deforested mountains and hills. In addition to causing flash floods that destroy communities, the waters also bring mud and silt down to farming regions. This mud and silt destroys the fertility of farming lands. The earth used to contain over six billion hectares of forest.
