Wait..................there is a virus going around ..........................what?
You know in the 1800s into the 1900s people raised and butchered their own to eat. The plants came about to serve the city demand.
So we could kill two birds with one stone here. Make sure each person has six foot between them and anybody else, meaning you would get rid of tall buildings, which would allow each person to raise their own food for the most part and then not worry about this stuff. Genius.
