In primitive society, people were respectful of nature. Primitive man did not, and could not separate himself from nature. He lived among forests, birds and animals. A powerful modern culture has not yet stood between him and nature. That is why he considered animals and plants as equal members of this world, creatures of the same blood, relatives. The man of modern society has built a man-made world between himself and the surrounding nature: he lives in heated houses; buys meat and vegetables in stores; in winter it is protected by warm clothes; he rushes in a car, throwing garbage through the windows, and pretends to be the ruler of the Earth.
