The V. I.Vernadsky''s noosphere doctrine and a geological science
The necessity of implementation of Vernadsky's noosphere doctrine for solving the present-day problems of man-nature interaction is substantiated in the article. In this connection, the concept of noosphere as a current state of biosphere, which Vernadsky regarded as a planetary shell, is considered to be the basic element of the noosphere doctrine. General laws of present-day man-nature interaction can be determined on the basis of study of the geological history of biosphere development.
