We don't actually even need to triple the production - depending on the country and crop, anything from 1/3rd to over 60% of production (!!!) is wasted [1].

This insanity has got to stop, and a lot of that waste in Western countries is caused by consumers wanting a 24/7-available selection of all kind of products in their nearest supermarket. And everyone who proposes solutions to that like requiring pre-ordering fresh meat and produce one day in advance (to curb the amount of what has to be thrown away at the end of each day) quickly gets branded a "communist" or comparisons with empty shelves in the former GDR/USSR crop up.

Additionally: It's one thing (and bad enough) if stores keep around a dozen brands of basic yogurt around as that stuff needs a time to expire and stores have got pretty good at keeping that loss minimal, but all that packaged fresh meat... :'(
