Philadelphia Eagles Go Green -- Literally

ABC News: "The Eagles have quietly become the most environmentally friendly team in the National Football League, and perhaps in all of major league sports.

When the lights come on for an Eagles game at Lincoln Financial Field, 30 percent of the power comes from so-called clean sources, such as wind power and methane reclaimed from landfills.

When the Eagles fly to an away game, their organization plants trees in the Philadelphia area to make up for the carbon dioxide emitted by the team's plane.

If you go get a beer at halftime, you'll notice recycling bins every 46 feet on the concourse. Why that distance? Because a study showed people will actually walk that distance to drop off a plastic cup for recycling; any further, and the cups will just be dumped with regular trash.

The team's tickets are printed on recycled paper. So are the programs. Even the machine that vacuums the field after the game runs on biodiesel.
