Stability of life on earth : principal subject of scientific research in the 21st century

This book shows how human activity on local, regional and global scales has perturbed natural biogeochemical cycles, "colliding" with Nature. The authors demonstrate how the scale and intensity of human-induced destruction of Nature and resultant feedback mechanisms have continuously expanded. They consider the likelihood of increasing numbers of natural disasters as a result of such activities, and propose that sustainable development become a principal research topic for the 21st Century.
