<br/><br/> "Our species' pervasive presence on the planet is the combined result of two powerful forces: earth's rich natural endowments and humanity's ability to manipulate nature. From our ability to control fire to our expertise in breeding palatable plants, from our capacity to ship fertilizer across the Atlantic to our skill in selectively tinkering with plant genomes, DeFries describes the ingenious manipulations of nature that have enabled humankind to nourish and flourish. Throughout history humans have been able to ratchet up populations, survive the hatchets that threaten the species, and pivot to a new strategy for survival"--
