Probably a part of his show (it is a show - not a serious nature program) is for real and partly fake.
His enthousiasm makes reptiles a little bit more understood by his viewers. And when this leads to f.e. a farmer that does not kill the snake he finds, but letīs it go, than the show was worth it.
I give him some credit because he means well.
But I think he also likes to make as much money with it as he can.
But who wouldnīt?
