environmentalists vs. the birds

From News of the Weird
(by way of the Atlanta Journal-Constitution)...

Many of today's environment-friendly new buildings are apparently terrible for birds. According to ornithologist Daniel Klem of Muhlenberg College, between 100 million and 1 billion birds are killed each year colliding with glass, with a big culprit being the generous glass construction on buildings meeting the rigorous energy and environmental standards of the U.S. Green Building Council.
