Supermarkets show their best produce whenever you enter their premises. Apparently, beautiful fruits and vegetables wet our appetite… and we buy more in the store. There’s one problem: Not all apples, potatoes, and carrots are beautiful. So the ugly ones are taken out, and that leads to food-waste. In 2013 Walmart began selling fruits and vegetables that would normally be deemed too ugly for displays. Now the giant retailer reports that, since the start of the program, it has diverted 82 percent of food that would have otherwise gone to landfills. That amounts to about two billion meals.
