Every year, about 8 million tons of fallen leaves end up in landfills.
That's according to Melissa Hopkins of the National Audubon Society, who offers alternatives to raking up leaves and throwing them away.
"A lot of people think that when leaves fall, you need to really quickly scoop them up and get rid of them," she tells NPR's Melissa Block as they take a look Block's backyard in Washington, D.C., covered in a blanket of leaves. "We think about leaves as vitamins. They are free vitamins that naturally occur in your yard."
Thursday in Pittsburgh, Republican presidential candidate and former Massachusetts Gov. Mitt Romney appeared to shift his position on climate change. Speaking at the Consol Energy Center, he said, "My view is that we don't know what's causing climate change on this planet." In his book No Apology and in earlier public appearances, Romney has said that he believes climate change is occurring and that humans are a contributing factor. At a campaign appearance in New Hampshire, back in August, Romney emphasized questions about the extent of the human role.
