The person passed through numerous evolutionary transformations before accepting modern look. The person - top of evolution live: existence of consciousness and ability to use instruments of labor distinguishes him from animals. Besides, the person can transform the nature, doing it convenient for the life, but not just to adapt to the available conditions.
Instruction
1. The fossil person living during paleolith era (from Greek palaios - ancient, litos - a stone), fitted into circulation of substances in the nature very organically. About 2.5 million years ago the person began to use stone instruments of labor, but it influenced the biosphere not strongly.
2. With the advent of agriculture, cattle breeding and operation of minerals the situation changed radically. The person began to interfere actively with circulation of substances, involving in it iron, fossil hydrocarbons and other substances.
3. Intensive development of the industry in the 18th century was caused by the accompanying discoveries. Naturally, such vigorous activity of the industrial enterprises strengthened impact of the person on the biosphere.
4. The created modern industry is characterized by extremely noticeable influence of the person on the environment. The person "adjusts" the nature to himself more and more and thinks of consequences less. Uncontrolled construction of the cities, destruction of forests and swamps, - all this perniciously affects the nature. Natural balance in the nature is broken.
5. Redutsenta - the microorganisms processing waste - any more not up to the end cope with the functions: too sharply garbage volumes increased. And a large amount of the substances produced by the industrial enterprises cannot be destroyed in the biological way at all (for example, plastic).
6. Natural resources are exhausted, the environment is polluted. It is necessary to understand that the civilization which is based on ideas of infinity of natural resources leads mankind to environmental disaster.
7. Having relied on will of elements, the mankind will die. It will be just destroyed by ecological crisis.
8. The only chance for mankind to survive - to develop a competent strategy. It is necessary to realize limitation of resources on the planet and to transform the biosphere of Earth to "noosphere" - "a reasonable cover". Being powerful geological force, the mankind has to be responsible for consequences of the activity.
