A report from the U.N. says that 33 percent of food produced is thrown away. This creates greenhouse gases. Part of the problem seems to have something with the supermarkets that encourage us to buy more. They put out such as buy-one-get-one-free to encourage us to buy more food. In Europe alone, people throw away 100 million tons of food every year.

Many of us throw away our unwanted, uneaten or out-of-date food. But the problem isn't just us throwing away leftovers in the fridge or cupboard. Although we all love the convenience, price and choice of food that supermarkets offer, a lot of food is thrown away before we even see it. BBC reporter, Caroline Hepker, looked into the problem in the USA and said "Food waste is a huge problem in America. Forty percent of all food goes uneaten and it's a problem that starts long before you get to the dining room table."

Another problem is the 'sell-by' and 'use-by' dates printed on food packaging. This confuses shoppers, including me. Anything older than a 'sell-by' date makes us think it is old and the food has gone off. But in fact, this is just the date until which supermarkets can guarantee its freshness. To stop us from wasting food, perhaps the best idea is that we all think twice before we fill our baskets up with too many groceries.
