About a third of the planet’s food doesn’t get consumed, here’s how you can help stem the tide from farm to landfill.It appears that food waste is having its moment, not only in terms of its rampancy, but in the mainstream media attention that it’s receiving. And from campaigns imploring us to love the ugly vegetables to supermarkets dedicated to selling surplus food, people seem to be understanding that the time to tackle the issue has come.Why is it such a big issue? I’ll tell you in mommy-lecture style (to be read in guilt-inspiring mom voice): 800 million people globally suffer from hunger; meanwhile, we trash enough food (2.9 trillion pounds a year) to feed every one of them twice over. This is why you should stop complaining and eat your vegetables.The statistics above are from National Geographic magazine, the March cover story of which addresses the topic of food waste. In it Elizabeth Royte writes of the moral issue of taming our wasteful practices, as well as pointing out the environmental toll created by producing food that no one eats. Amongst some other truly mind-boggling numbers, she notes that if food waste were a country, it would be the third largest producer of greenhouse gas in the world, after China and the United States. Growing the 133 billion pounds of food in the U.S. that markets and people throw away annually uses the equivalent of more than 70 times the amount of oil that was lost in the Gulf of Mexico’s Deepwater Horizon disaster. Oy.
