Food waste is the world's dumbest problem


Since 1999, the FoodCam has helped to nearly eliminate food waste at one MIT lab. Any time someone has leftover food at the lab, they can place it under a camera and hit a button, which then triggers the FoodCam to take a photo of the food and post it to slack, Twitter, and an email list. The simple invention has significantly reduced food waste, representing a small positive change to a serious global challenge.
