Charles C. Mann Quote
Rocketing up the growth curve, humankind every year takes ever more of the earth’s richness. An often quoted estimate by a team of Stanford biologists is that humans grab about 40% of the present net primary production in terrestrial ecosystems—40 percent of the entire world’s output of land plants and animals.
