Good question. I bet so. Locally if things got really bad and food supplies dried up then I bet the Deer population would be destroyed.
If we start seeing a run on hunted food, because meat is getting more and more unavailable from the store, I don't think you'll have lots of problems getting used to it!Lots of deer in my area, luckily. Better become a fan.
I've been teaching people how to urban garden with great results. Built my chicken coop this weekend and plan to add chickens to the homestead (we have less than an acre).The US produces more food calories per acre than any other country in the world, of course the population has been migrating to the urban areas for the last 100 years in exponential numbers so...
hopefully people will embrace urban farming & take some burden off the overstressed agriculture & transport industries
