We waste a lot, tons and tons. In the world we throw out about 1.3 billion tons of food a year, or a third of all the food that we grow. In poor countries waste occurs on the farm or on the way to market; lack of refrigeration being the culprit. In wealthy countries we are the main cause - We buy too much food. We don’t finish our plates.About 40 percent of wasted food is thrown out by consumers.
We in the United States waste more than $160 billion in food a year.
