Innokenti Gerasimov was known as the specialist in conservation and changing the natural environment. On the need of environmental protection, Innokentiy Gerasimov had spoken at a meeting of the Department of Earth Sciences, Soviet Academy of Sciences, on February 16, 1965. He has discussed the anthropogenic influence of paper industries on an ecosystem of Lake Baikal. In his report, there was an alarming warning about the increase of industrial and domestic wastewaters from 11 to 60 km3 per year for 20 years. Taking into account the need for dilution and subsequent self-cleaning of 5–10 times the amount of clean water meant a threat of an acute water crisis in especially important industrial regions of the country. Innokentiy Gerasimov was supporters of the idea of Soviet ecologist Stanislav Shwarts, that the industrial needs of the Soviet Union made impossible the total preservation of its natural environment. According to him the Natural Environment should be modified by humans to provide all people's needs and the nature reserves (zapovedniki) should keep untouched environment. Books and articles
