Would you like to be helpful even after you're dead? According to Newsweek magazine, tree huggers are going after more than your SUV they want to revolutionize the way we rest in peace-- It's time for so-called "green" cemeteries. There are hundreds of them across Europe and Africa, and they're starting to catch on in the United States. A green cemetery offers some eco-friendly alternatives to traditional burial methods. They don't use wooden caskets because they stay intact for centuries--And they avoid cremation, which wastes energy and pollutes the air. Instead, the most environmentally correct solution is burial in a biodegradable shroud made from cardboard or cloth. The third and largest cemetery like this in the United States just opened in November in Texas and they don't permit individual headstones either. This natural, or green cemetery is on 81 acres in Lake Livingston, Texas. It accepts people of all faiths even family pets are welcome-- And that's the scoop on the latest trend in 'green' cemeteries from the experts at Newsweek.
