 who, with his 1926 book The Biosphere, in the tradition of Mendeleev, is credited with formulating a physics of the earth, as a living whole. Vernadsky distinguished three spheres in the universe domain

In biology, evolution is change in the heritability trait of a population of organisms from one generation to the next. These changes are caused by a combination of three main processes: variation, reproduction, and selection....
, and that the higher spheres modify and dominate the lowers:

  1. Abiotic sphere - all the non-living energy and material processes
  2. Biosphere - the life processes that live within the abiotic sphere
  3. Nöesis or Nösphere - the sphere of the cognitive process of man


Human activities (e.g., agriculture and industry) modify the Biosphere and Abiotic sphere. In the contemporary environment, the amount of influence humans have on the other two spheres is comparable to a geological force (see Anthropocene
Anthropocene

The term Anthropocene is used by some scientists to describe the most recent period in the Earth's history. It has no precise start date, but may be considered to start in the late 18th century when the activities of the humans first began to have a significant global impact on the Earth's climate and ecosystems....
