Yet, at the exact same time, humanity has never been better. Our numbers continue to swell, life expectancy is on the rise, child mortality is declining, and the rising tide of economic growth is lifting most boats. So which is it: Are these the best of times or the worst of times? Or both? And how imminent is our doom really? In the September issue of BioScience, a group of scientists attempts to reconcile the conflict and answer the question: “How is it that human well-being continues to improve as ecosystem services decline?” The authors, led by geographer Ciara Raudsepp-Hearne of McGill University, offer four hypotheses for this “environmentalist’s paradox”: humans are actually worse off than we think; the ability to grow food trumps all other ecosystem services as far as humans are concerned; technology has allowed us to transcend the environment; and the ill effects of environmental degradation lag its benefits, i.e. the worst is yet to come. …
