i completely agree, if he ate them it wouldnt be so bad. and im not talking one bite for the camera. the main concern is that its killing endagered species to demonstrate edibillity, when there is a collection of camping grub available and you could just as easily say "oh yeah and if i wanted to i could bash that adder on the head with a rock and cook it and eat it, but because its unnessicary and my crew has food i will just eat the equivalent in rations" or something similar.
and to the rabbit coment, you cannot compare killing an endagered species to killing rabbits either, but i do get your point and i would still consider it unnecessarily stupid if it were any other protected species, not just reptiles.
