NEW YORK, NY - JANUARY 10: Hot dogs are heated on January 10, 2013 in New York City. A new London-based study by the The Institution of Mechanical Engineers found that as much as half of the food produced in the world ends up going to waste. The study found that irresponsible retailer and consumer behavior contributed to 1.2 billion to two billion of the four billion metric tons of food produced globally that goes uneaten.
