So a third up to half of all food grown is wasted. While that's disgusting in and of itself, what's almost as worrying is that it means that a large amount of the water, energy etc that goes into food production is ALSO wasted. Do you know of--or can you think of--innovative ways to improve this situation? Can you identify root problems and offer suggestions for fixing them? Can you identify the harmful consequences and find/think of ways to mitigate them?
