Jim Robbins writes in the New York Times October 14 that some experts find that habitat fragmentation is the biggest of all environmental problems. “By far,” said Dr. Michael Soulé, a retired biologist and founder of the Society for Conservation Biology. “It’s bigger than climate change. While the serious effects from climate change are 30 years away, there’s nothing left to save then if we don’t deal with fragmentation. And the spearhead of fragmentation are roads.”
