Glass Houses

(Fox News) - Many public and private institutions have constructed all-glass, environmentally friendly buildings in order to go green, save power, and blend in with nature. But the Atlanta Journal Constitution reports these buildings have turned into bird killers on an incredible scale. Ornithologist Daniel Klem of Muhlenberg College says that between 100 million and one billion birds die in the U.S. each year in collisions with glass.

The chief environmental officer at Atlanta's Emory University describes its glass mathematics and science center as a slaughterhouse — and refers to it as "the wall of death." Many owners are now putting black mesh netting or large drapes over the buildings — in order to save the birds.
