Vladimir Vernadsky and Environmental Science



Vernadsky participated in the First General Congress of the zemstvos, held in Petersburg on the eve of the 1905 revolution to discuss how best to pressure the government to the needs of the Russian society; became a member of the liberal Constitutional Democratic Party (KD); and served in parliament, resigning to protest the Tsar's proroguing of the Duma.


He served as professor and later as vice rector of Moscow University, from which he also resigned in 1911 in protest over the government's reactionary policies. After the February revolution of 1917, he served on several commissions of agriculture and education of the provisional government, including as assistant minister of education.

Vernadsky first popularized the concept of the noosphere and deepened the idea of the biosphere to the meaning largely recognized by today's scientific community. The word 'biosphere' was invented by Austrian geologist Eduard Suess, whom Vernadsky met in 1911.

In Vernadsky's theory of the Earth's development, the noosphere is the third stage in the earth's development, after the geosphere (inanimate matter) and the biosphere (biological life). Just as the emergence of life fundamentally transformed the geosphere, the emergence of human cognition will fundamentally transform the biosphere.

In this theory, the principles of both life and cognition are essential features of the Earth's evolution, and must have been implicit in the earth all along. This systemic and geological analysis of living systems complements Charles Darwin's theory of natural selection,which looks at each individual species, rather than at its relationship to a subsuming principle.

Vernadsky's visionary pronouncements were not widely accepted in the West. However, he was one of the first scientists to recognize that the oxygen, nitrogen and carbon dioxide in the Earth's atmosphere result from biological processes. During the 1920s he published works arguing that living organisms could reshape the planets as surely as any physical force. Vernadsky was an important pioneer of the scientific bases for the environmental sciences.
