10 and all the TV/movie people who traipse through other countries are generally under very strict RULES and LAWS regarding what they can do with creatures.
Given the concept of this show, I would expect they must actually purchase a lot of the critters they use and be under very explicit contracts
They would certainly have to pay for the elephant guest appearance, etc.
Touching any real wildlife I expect would be a big no,no,no..........interesting when you consider how they must arrange this kind of stuff
Survivor got in real shit for removing something from I think Great Barrier reef and taking it to camp during the one they filmed here
