Quick, look in your refrigerator. If you were to clean it out, how much of it would you have to throw away?
You probably have Tupperware containers of this month's leftovers and probably half a dozen fruits and vegetables that are past their prime. And if you count the remains of last night's dinner stinking up the trash can, you're looking at several pounds of wasted food in your kitchen.
The waste in your home is likely to be repeated in millions of other U.S. households. Then think about every unfinished plate at restaurants nationwide and thousands of buffet lines, grocery stores and dining halls at closing time.
All told, Americans throw out between 25 and 50 percent of the food produced in this country, according to estimates. On the conservative side, that's more than $100 billion in food going to landfills every year.
Wasted money isn't the worst of it, says writer Jonathan Bloom, who blogs at Wasted Food (www.wastedfood.com) and is working on a book about the subject. That food rotting in landfills, because it isn't decomposing with the help of oxygen, is creating millions of tons of methane gas, which scientists say is more than 20 times as harmful as carbon dioxide to our atmosphere. Eighteen percent of what goes into landfills is food, and landfills are the largest human-related source of methane.
"People who grew up after World War II don't value food the same way as those who lived through the Depression, when rationing happened and people had to grow their own food. Wasting food was [seen as] helping the enemy," Bloom says. "The stakes are even higher [today] if you talk about global warming."
Even though there is more food waste at the commercial level, widespread change almost always starts at home.
"In the household setting, people have power to effect change and reduce the amount of food that gets sent to landfills," Bloom says.
