He even can decide not to do it, naturally with death as result, which by the way also is his own free choice. Within the evolution it is quite impossible for the living beings to make similar decisions, because they have no free choice at all. Inevitably during his growing to maturity this freedom of man also causes many disastrous situations. They are always related to people's enjoyment of power which evokes the desire to rule over nature and people. On the one hand one believes that it would be possible to improve nature so that her products are more useful to man, and on the other hand one hopes to make more and more profits.
More profits means more power, so it happens to be a desirable aim.
But these corrections of nature always, sooner or later, turn out to be deteriorations. For example the unbridled use of fertilizer ruins the cohesion of the biological world, in the end even people's health. The only reasonable purpose for the conversion of nature is not to obtain power, not to make profits, not to improve nature or civilization, but only to make possible real living for man.
