Does a man may decide biosphere's fate?
A man is a decisive factor of evolutionary fate of all nature now. A
self-removal of the natural selection was a result of mankind's
development and a result of its negative unecological activity bore
the nature of accidental unthinking actions. Does a man ready to this
very important role of " Great creator of nature"? There is no doubt
about that a man ready not absolutely to this role. A self-removal of
the natural selection was begun many centuries ago (after "neoanthrop"
appearance). The progressive evolution of man was slowed down after
this appearance.  The selection stood not man's activity against the
What results will get by disappearance of natural selection? 
The natural selection fastens the signs:
Allow supporting the ecological balance.
Are useful for organisms.
Are attractive by sexual selection (beautiful slender body, beautiful
face, rich hair, etc.
Are "norms" of species beauty; there is a hard extermination of
persons with violations of external signs norm.
Prevent a possibility to inherit dangerous sickness.
Encourage slenderness, flexibility, and a normal weight.
The "rational" adaptation (a man adapts himself to biosphere
conditions) fastens the signs:
Allow not supporting the ecological balance, 
Are harmful for a man (vices, etc.);
Are useless by sexual selection (physical imperfection of body, bald
head; bodybuilding, rare physical perfect persons (sportsman). 
Allow big possibilities for deviation from norms, a "wash-out" of
beauty, a reduction of beautiful faces quantity by increase of
Make it possible to inherit dangerous sickness.
Allow unnecessary weight, low physical activity by use of different
There are other negative results. 
A man has no right to expel the natural selection from nature of
earth. The mankind may lose important reliable source of beauty and of
expedience of nature. A man must preserve ecologically proven
territories of earth in wild condition (the natural selection cannot
act in artificial conditions of anthropogenic territories). A man must
begin the ecologization of all activity and all own needs.  It is
possible a man must think about maximal approach of own activity to
the basic natural selection principles.
