No need to have to grow all their own food, any kind of a supplement at all is a positive.

Plenty of single family dwellings with grass yards.

And time commitments/work involved? I guess they aren't serious about climate change. This just reinforces my original point. Screeching about climate change but unwilling to do any of the work or make any _real_ sacrifices.

It only takes a few hours a week to operate a backyard garden that produces more than even a large family can consume.
