#108: Eat Your Heart Out (Friday, January 16)

The Impact: Nearly one third of all food produced each year in the U.S. for human consumption ends up in the garbage. That's 48 million tons of food (about 160 pounds per person) wasted each year that could've fed nearly 50 million people.

The Idea: If it's on your plate, eat it...or take it to go, but don't throw it out. Think about the person who would have loved to have your leftovers. And if you're not a leftover person, take it to go and give it to a homeless person on the street.

You can also choose to eat at restaurants that donate unused food to local food programs, such as City Harvest in New York. When you make reservations, ask if the restaurant participates in such a program.

The Result: You'll save money and conserve energy used to process that food into landfills. Plus, it takes less energy to reheat leftovers than it does to cook a new meal.
