It's standard behavior there.
I know someone from the deep amazon brasilian states and there is a complete disregard in the person when trying to have a civil discussion about conservation. And it is very easy to infer that it is not an isolated case but a standard way of life and thought.
Because there is so much land and so much wilderness, paired with so much distance from developed areas and a lack of a truly organized central government, people feel in the right to take what they want, when they want it, with no fear for reprimand.
This is a person that just picked a piece of land on the end of an undeveloped area, where a dirt road was open, cut down some of the vegetation to outline an area and then just set fire to it to clear the land for building. No concern for safety, building codes, building permits, sewage and eletrical infrastructure, nothing. Because, and I quote, "if you leave it be, in one year everything grows back".
And when it comes to animals, anything is fair game. Monkeys, leopards jaguars (take in mind large cats are generally not considered as food anywhere in the world), alligators, all kinds of wild fish and birds - including macaws and tucans - capibaras, tapirs, anything and everything is on the menu because, and I quote again, "the jungle is full of creatures".
This is plain disregard towards the basic notion of being civilized.
