This outlook goes unchallenged because of a perception that
environmentalism is a
pragmatic solution to purely scientifically - defined problems, and a belief that it can be answered in purely scientific terms.
Last year the Breakthrough Institute, the
pragmatic think tank that's been a thorn in the side of traditional
environmentalism since its inception in 2003, published an essay by Peter Kareiva, chief scientist of The Nature Conservancy; Robert Lalasz, TNC's director of science communications; and Michelle Marvier, an ecologist at Santa Clara University.
