Thanks for the link Chlidonias. I do not have the patience to read the whole thing, but I read the first part and I find some serious flaws. The part I read said that habituation to people in nature reserves causes wild animals to actually go through the process of domestication. Yet the examples they cite are of animals that are bred in captivity for domestic traits (NOT animals that have remained in the wild).
They also highlight urbanization (that is the part where I left). Of course animals in cities will behave differently, but is that necessarily bad? I mean we are not going to move people out of cities so that the animals can revert to their "most natural" behaviors. So if they need to adapt their behavior to survive well in the new urban environment, and it is clear they and their offspring will always be in an urban environment, why is it bad that they are learning new survival skills? And what in the world do squirrels in suburban neighborhoods have to do with ecotourism anyway?
