NFL Making Sure Super Bowl Stays Green

PHOENIX - The NFL is working to make sure the Super Bowl stays green.

From planting 10,000 new trees in Arizona to donating thousands of pounds of leftover food to soup kitchens and shelters, the NFL Environmental Program is trying to make the pinnacle of professional football an example of environmentalism.

Renewable energy sources, including wind power, geothermal, low-impact hydro and landfill gas -- will power the University of Phoenix Stadium in Glendale, Arizona on game day.

They were also used to power the adjacent NFL Experience street party for the five days leading up to the game.

Another environmental program includes planting 10,000 new trees on 100 acres of eastern Arizona land burned in 2002 by the largest wildfire in state history. The fire charred 469,000 acres and destroyed 491 homes.
