THE STUDY OF THE BIOSPHERE The term 'biosphere' first appeared in the works of the French biologist 1.-B. Lamarck and the Austrian geologist E. Suess in the 19th century. In the 20th century, the study of the biosphere attracted considerable attention, largely due to the research of V. I. Vernadsky (1863- 1945).

Several terms have been suggested for the science of the biosphere, including global ecology (a discipline studying the global ecological system, whose meaning is close to that of the biosphere). One of the most prominent predecessors of Vernadsky was his teacher V.
