Geochemistry and the Biosphere is a meticulously edited, reader accessible, first English translation of the Russian essays by Vladimir I. Vernadsky (1863-1945). Vernadsky is the highly venerated father of several geo-based disciplines, including geochemistry, biogeochemistry, and radiogeology. He wrote the first scientific theory about the "biosphere," the life zone of the Earth, and in the process laid the groundwork for planetary thinking. A recognized catalyst, this premier scientific work addresses in detail humanity's impact on the living systems of the planet. Geochemistry and The Biosphere contains his groundbreaking work on the biosphere and the noosphere, as well as his seminal work on geochemistry."
