Meat will be, I believe, an issue on price and availability. Mike can clue us in on that. Supposing it is, there will be some hunting/poaching pressure increase.
I don't think city/suburb folk will focus on wild game. Those who live out further may. If you have a few head of cattle then hunting/poaching won't be high on the list but if you are in the country without livestock then those will be the people most likely to increase hunting/poaching.
You are right, there will be an uptick in hunting/poaching. I don't think it will be a groundswell of increased hunting/poaching because it won't be easy and so long as there are beans and rice, etc., most people will stay at home.
