There is room for improvement, and there is significant financial incentive to realize that improvement. That said, I'm not sure that measure is the whole picture. If we are losing 30% of our food to the supply chain, what is the alternative? Perhaps we could farm things more locally and shorten the supply chain? If we did that, would we still get 100% of the yield of the old approach? What I am saying is that if we try and fix the waste problem, it would very like be at the expense of reducing yield. The extreme example is the tomatoes I am growing in my back yard. None of them will be wasted, but I'm fairly certain that the yield per square acre is absolutely atrocious.
