You’d be surprised how much food an urban homestead can produce. And no, one person isn’t going to feed everybody on food stamps but like many things, if enough people start doing it then it becomes part of the culture. Imagine if houses had a little homestead instead of a grass lawn, especially in the front. Whole changes in culture could occur. For example, one of the best things about Halloween in my opinion is that the whole neighbourhood comes alive with people out and about. If people spent more time in their front yards doing gardening (and not noisy polluting lawn mowing) there’s be more interactions between people and places would feel more alive and safer. </rant>
