Food waste has always been a serious problem. Between 33-50% of all food produced globally is never eaten and the value of this wasted food is worth over $1 trillion! To put that in view, in the USA food waste represents 1.3% of the total GDP. Food waste is a massive market inefficiency, the kind of which does not persist in other industries.
Meanwhile 800 million people go to bed hungry every night. That is 1 in 9 people on the planet who are starving or malnourished! Each and every one of them could be fully fed on less than a quarter of the food that is wasted in the USA, UK and Europe each year.
Food waste is really bad for the environment. It takes a land mass larger than China to grow the food each year that is never eaten, land that has been deforested, species that have been driven to extinction, indigenous populations that have been moved, soil that has been degraded and all this just to produce food that we then just throw away. In addition, food that is never eaten accounts for 25% of all fresh water consumption globally. Yikes!
