microorganisms. The layer of earth
1 cm thick is formed century, but it
is possible to destroy it for 1 field
season. It leads to desertification
and dehydration of natural
landscapes.

and to switch to more environmentally
friendly ways of industry.
2. It is worth using less electricity, so
people I will save resources of Earth.
3.To pay much attention to preservation
of the water preserving and protective
functions of the woods, preservation and
