The biosphere is a part of the biological shell of the Earth, the properties of which are determined by the activity of living organisms. The doctrine of the biosphere was created by the Russian geochemist V. I. Vernadsky. According to him, the biosphere is the shell where life exists or has existed.

The biosphere covers the entire surface of the land, seas and oceans, that part of the bowels of the Earth where there are rocks created by the activity of living organisms - coal, oil, gas - biogenic substances. In the depths of the solid part of the Earth, active life penetrates in some places up to 3 km (bacteria in oil fields).

In the atmosphere, the boundaries of the spread of life are limited by the ozone screen at an altitude of about 20 km. It blocks the damaging ultraviolet rays of the sun.

Vernadsky called the whole mass of organisms of all kinds the living matter of the Earth, which constantly redistribute in the course of metabolism chemical elements in nature, carry out the cycle of substances.

Life has created a soil layer on the surface of the land. Mineral components, decaying organic substances and numerous microorganisms are so closely interconnected in it that Vernadsky attributed it to special, bio-inert bodies of nature. The waters of the World Ocean have the same bioinert composition, saturated with countless inhabitants to the bottom of the deepest depressions of 10-11 km.

The inert substance of the biosphere is formed by processes in which living organisms do not participate. For example, igneous rocks.

The part of the biosphere that is under the influence of active human activity is called the noosphere - the sphere of the human mind. Most often, the impact of mankind on the biosphere is detrimental, which in turn is detrimental to humanity.
