What does mankind bring to the nature? in new york zoo at the end of an exposition behind the crates of lions and tigers a stone low-built building is located. the strong thick lattice reserves glass showcase. the inscription above it says: "the most dangerous animal in the world! " and when the intrigued visitor cautiously approaches his face to the lattice, he himself: a back wall of a crate is a mirror! certainly, it is a joke, but bitter joke, and it contains the deep sense and reproach. yes, just the man, crowing point of development of an alive matter on the earth, owner of the earth, carries not separate animals, but whole species before him. the history of three last centuries knows many such examples. fauna of the earth has began to fall intondecline, the processes of evolution have been broken. the new terms were born: instead of «dying out animals» more often tell «disappearing animals». the influence of the man on wild animals appears in two ways: direct influence (destruction or, on the contrary, protection, saving) and indirect influence through changes of their existence conditions. the man on the earth creates a new landscape. it is the irreversible and natural process. and it is not only irreversible, but it is also inevitable, because it is consequence of a human society development. some changes of a landscape are rough and obvious. they are ploughing up of steppes, cutting of woods, irrigation and other modifications of an earth surface changing its shape in radical way. as a result the whole complexes of animals begin to disappear because they have no place to live. but it is only one side of a question. direct influence of the man is a terrible scourge for the animals. the pioneers of the largest modifications of the earth surface become the main butchers of the animals. the poachers armed with long-range guns, high-speed motor boats, searchlights and automobiles exterminate hundreds of thousands of birds and animals. careless business managers pollute seas, lakes and rivers by petroleum or by sewage. laws declaring outside of the law any predatory bird, regulating even the prize for their murder cause irreparable damage. recently birds, which live on fish such as seagull and herons were persecuted. it is nothing but barbarity! for struggle with insects-wreckers one have begun to apply various poison chemicals, which can accumulate in organisms of animals in fatal dozes. this can cause mass destruction. many animals perish on highways. unreasonable planning of hunting of fur-bearing animals without registration of their number, unreasoned acclimatisation, and fashion whims stimulating sudden increase of demand on some animals - all these reasons have a common consequence - destruction of animals and of biological diversity.
