LIFE IS DEPENDENT UPON EARTH CONDITIONS 195

Our Farm Lands Are Headed for the Sea.

Someone has said that "dictatorship, rather than democracy, has

characterized civihzed man's attitude toward nature during many ages

in the past." Instead of cooperating with nature, we have tried to

When the natural processes of erosion are disturbed, soils, which

took centuries to deposit, may be removed in only a few years. This

process is called accelerated erosion.

If our soil continues to be carried away at the present rate, our huge

dams and reservoirs will become useless within a hundred years; Mead

Lake, impounded by Boulder Dam, will fill up.
