Symposium Introduction
Exhaustible resources.
Finite resources are divided into renewable and nonrenewable.
To include renewable plant and animal life, soil fertility. Of
number of renewable natural resources important role in human life is
forest. The forest is of considerable importance as a geographical and ecological
factor. Forests prevent soil erosion, detain surface water, ie
serve vlagonakopitelyami contribute to the maintenance of groundwater levels. In
forests inhabited by animals, representing the material and aesthetic value
for man: ungulates, fur and feather. In our country the forest cover
About 30% of its land and is one of the natural resources.
For nonrenewable resources are minerals. Their use
man began in the Neolithic. The first metals that have found
application, were native gold and copper. Extracted ore containing copper,
tin, silver, lead could have for 4000 years BC Currently
people, involved in the scope of its industrial activity the greater part
known mineral resources. If at the dawn of civilization man has used
for their own needs only about 20 chemical elements in the early XX century - about
60, now more than 100 - almost the entire periodic table. Annually produced
(extracted from the geosphere), about 100 billion tons of ore, fuel, mineral
fertilizers, which leads to the depletion of these resources.
