"The bottom line is that the growth of the world economy has meant a roughly commensurate growth in human impacts on the physical world, not an escape from such impacts. These anthropogenic impacts are now so significant, and indeed threatening to the sustainable well-being of humans and other species, that Nobel Laureate Paul Crutzen (a codiscoverer of the human-induced loss of stratospheric ozone) has termed our age the Anthropocene, meaning the geological epoch when human activity dominates or deranges the earth’s major biogeophysical fluxes (including the carbon, nitrogen and water cycles, among others)."
