Food is on many of our minds. How it's grown. How to make it. Where to eat it. But don't forget what happens to it after you're done. Today is World Environment Day, as established by the United Nations Environment Programme. This year's theme is Eat.Think.Save, emphasizing reducing both food waste and food loss.

Each year 1.3 billion tons of food is wasted in the world. In the U.S., 30% of all food is thrown away each year. All the wasted food can certainly feed a lot of people. Wasting the raw resources used to produce the food is bad for the environment and for out growing population. We need to think about ways each of us can help to stem food waste and loss.

Here's a piece on food waste ties with water waste from NPR. Out of the 1.3 billion tons of food wasted worldwide, 45 trillion gallons of water is wasted. That's a LOT of water. Another reason to watch what we waste.
