This illustrates why Chicoms can't be trusted.
There's too much money to be made in the illicit trade.The price of a banned animal will rise and "some" people will not be able to bypass the high profits to be made with them.
On the other hand,if an animal's trade is banned and people stop or just slow the harvesting of them,then we could be looking at an overpopulated and weak group of critters that would be even more likely to spread disease.
