They are just super Fat lol... I live around iguanas and I have never seen them act like that. Usually they are scared of humans.

They are living the good life!!

I guess this is the behavioural change from frequent human visitation. They say that they are trying to combat this by reducing the tourist visitations and restricting them to existing spots and not expanding to new ones.

Well I bet once the tourist stop visiting that area those Iggys might die. Most of them are probably dependent on humans now.....Stuff like that happens all over the world.

It's a shame because they're endangered species, and obviously it's better that they survive than to face extinction albeit living completely naturally and untouched.

That is true....It is hard to say what is right....I guess they are just outdoor pets now :)
