I totally agree, but not with its feasibility. Wouldn't this only be possible in a non-globalized world with far fewer humans where everyone could grow their own food and be self-sufficient within their communities? I'm pretty sure I can't get my lentils locally. Similar reasoning my other foodstuff; waste is pretty much the standard. Or I'm just making excuses because I've grown accustomed to the convenience of getting all my stuff in one place.
