Volodymyrs childhood was spent in Ukraine and he studied in Kharkov for a brief period of time. When the family moved to Saint Petersburg, he continued his studies at the Saint Petersburg Grammar School. Here, he developed an interest in science, specifically in natural sciences.

Early Life and family

3 Vernadskyi presented his famous report on the Paragenesis of Chemical Elements in the Earths Crust in front of the 12th Congress of Medics and Natural Scientists in This study laid the foundation for what was later known as geochemistry. He advocated researchers to use radioactive phenomenon in studying the history of chemical elements and in seeing the relationships between these elements.

4 Vernadskyi was among the first scientists who realized that the presence of nitrogen, oxygen and carbon dioxide is a direct product of biological processes. He also published is research in the 1920s, stating that living organisms have a large impact on how the planet evolves.

5 However, Vernadskyi is probably best known for his development of the idea of the biosphere of the Earth and his ideas on the evolution of the biosphere into the noosphere. He defined the boundaries of the biosphere by showing that the biosphere includes all the hydrosphere, part of the troposphere - the lowest aver of the atmosphere and the upper part of the Earth's crust. For Vernadsky, the biosphere had existed since :he very beginning of the Earth's history and it vas constantly evolving. Our present living world is the product of a long and complex evolution of the biosphere.

6 Vernadskyi believed that human reason and combined scientific efforts could overcome the negative results of technology and could lead to a afe future for everyone. This positive evolutionary stage of the biosphere of the Earth is for him the noosphere, the sphere of reason. In his paper, Several Words on the Noosphere 1944,( the last paper he published before his death), Vernadskyi outlined the conditions that were required for the creation of the noosphere: equality for all people and an end to wars, poverty and hunger. Today, Vernadskyi's vision of the world is more important than ever before.
