I agree. We should also stop subsidizing agriculture, there is enough food grown around the world for everyone. All this waste is very inefficient!
In fact, we dump our cheap overproduced food on third world countries and collapse their ag. sector. If we stopped producing and switched to importing we would boost their economies.
Since food can be grown in almost any country on earth, we would have a diverse supply chain. I'm sure nothing would go wrong with this plan./s
