James Gustave Speth takes a long view of the environmental movement. He was on board at its dawn, co-founding the Natural Resources Defense Council right out of law school in 1970, then serving as President Carter's environmental advisor, and, in the 1990s, directing the UN Development Programme. The warnings in his Red Sky at Morning (Yale University Press, $24) are not novel, but his book provides an even-handed history and analysis of the movement. He argues that global treaties are doomed because national self-interest undercuts them and explains why an unconstrained market will invariably promote "consuming nature's capital and counting it as income." While recognizing the costs of globalization, Speth also sec its potential as a force for conservation. He argues for the promise of public-private partnerships and small-scale initiatives (like the pledge by Home Depot to avoid buying endangered wood). It's perhaps no accident that Speth's book reads rather like a textbook--he's dean of Yale's School of Forestry & Environmental Studies.
