Earth system science
Earth system science (Gaia hypothesis) is a term used to describe science that studies the whole Earth as a system of many interacting parts and focuses on the changes within and between these. When scientist James Lovelock worked for the centre of space research, the Jet Propulsion Laboratory (JPL) California he was asked by NASA finding out what is it that makes life on a planet possible as they prepared for their space travels in the 1970s.
The Gaia hypothesis
Lovelock did the study on Earth and he discovered with his mind’s eye our planet as something possibly unique in the universe, something alive. He named it Gaia hypothesis (Gaia means mother in Greek). Since then other scientist re-named it Earth system science. Earth system science is an approach to understanding the Earth as a number of interrelated systems and provides a physical basis for understanding the world in which we live and upon which humankind seeks to achieve sustainability.
