At his hog farm about a dozen miles from Las Vegas' famed strip, Bob Combs became a celebrity of sorts for hauling thousands of pounds of leftovers from casinos' all-you-can-eat buffets and feeding it to his 3,000 pigs.

Farmers used to call the practice "garbage feeding." Today, researchers see it as a tool for stemming climate change. That's because the growing amount of wasted food around the world adds methane, a potent greenhouse gas, to the atmosphere as it rots in landfills.

Combs just happened to be a pioneer recycler.
