environmental change  

Définition

  • The major global changes of the past 2 million years have been driven by planetary biophysical forces. The waxing and waning of the great ice sheets of the Pleistocene (covering 30% of the Earth's surface at their maximum extent), with concomitant falls and rises of sea level, the shifting of climatic belts, and the responses from flora and fauna were all outside the frame of human impact if not of human presence.
