About the book: 1963 / "Red and Green" is a science fiction novel about the extraordinary invention of a Soviet biologist. Developing and expanding the hypothesis of Timiryazev and Nyssky about the convergence of plant chlorophyll and blood hemoglobin - about the connection between these two complex and still most mysterious substances of the organic world - the scientist managed to create a special preparation - “green substance”. With its help, animal organisms, like living green plants, acquire the ability to assimilate carbon dioxide from the air. Such green animals can live by directly absorbing the radiant energy of the sun, freely dispensing with organic food. Illustrations by A. Kadushkin.
