Nope, but we can reduce waste by raising prices for instance by ending farm subsidies. We can mandate the removal of (or at minimum the regulation of) expiration dates on food. Also, educating people about food. People assume that milk goes bad the second the clock rolls over on the unregulated 'best-by' date, so there's incentive to goose the numbers to raise sales. Further, slightly sour milk can be used as a substitute for buttermilk in baking, for instance, but people have to learn that. [1]
Any competing plans you'd like to share that allows us to avoid losing unfathomable quantities of limited fresh water and raising a ton of animals so they can be hucked onto a landfill?
