In Harmony With Nature

Abilities and powers of man are increasing now. Technological progress allowed to use nuclear, chemical, laser, biological, and other machines and technologies instead of hand-operated and mechanical techniques. However, scientific and technological progress, as a rule, was separated from social progress. Such approach has let man use the means negative consequences of which are globally destructive. 100 billion tons of minerals are mined annually, and more than 90% of them go in waste. Amount of oxygen, consumed by certain countries, already exceed its manufacture by the plants of these countries. Tropical forest-main ‘lungs’ of the Earth- is more than 40% felled. The speed of its felling is more than 20 hectares per minute. Almost one thousand of species of animals and 25 thousand species of plants are now under the threat of extinction. Recently medicine has faced the problems of worsening natural ecological unknown by now. Felling forests, pollution of environment by industrial waste and automobiles have already caused global warmth on the planet. Misuse of pesticides, mineral fertilizers, water pollution, impact of Chernobyl accident on the people-this is not a complete list of the factors determining dangerous changes in the cells of human organism and growth of diseases and death rate. Man is now using permissive principle and its trying to take everything from his life today. Mankind has driven itself into a dead-end…. However, we still have an exit from it. It is indisputable that solution of the problem of preserving the quality of the man’s life is impossible without solving ecological problems: preservations of genetic fund of flora and fauna, preservation of clean and productive natural environments (atmosphere, hydrosphere, soils, forests), preservation of ozone. Only having realized that the reason of ecological crisis which burst in the 20 century was lack of unity of Man and Nature, civilization can achieve progress.
