14. Translate the following text into Ukrainian in writing:

Erosion is the modern symptom of maladjustment between human society and its environment. Men are permitted to dominate Nature on precisely the same conditions as trees and plants, namely on condition that they improve the soil and leave it a little better for their posterity than they found it. Agriculture in Europe, whatever its other weaknesses, has been, and perhaps still is, a practice tending on the whole to increase its fertility. The illusion that fertility can always be restored by applying some of the huge amounts of artificial fertilizers now available has been shattered by the recognition that fertility is not merely a matter of plant-food supply, but it is also closely connected with soil stability. An exhausted soil is an unstable soil. Nature has no further use for it and removes it bodily. Whereas under normal conditions a fraction of an inch of soil may become exhausted and be removed in a century, under human control the entire depth of soil may become exhausted and be eroded in a few years.
