A United Nations report reveals that 1.3 billion tons of food produced for human consumption gets lost or wasted each year, accounting for one-third of the total food supply.
Fruits and vegetables, as well as roots and tubers, are among the foods that are thrown out the most. In wealthy countries, consumers waste almost as much food as the entire net food production of sub-Saharan Africa.
All of that waste has to go somewhere.
Although much of it ends up in landfills, there are potential remedies for this monumental problem in the form of some innovative new technology.
