there needs to be signs posted, or educational material otherwise available, that warns people that gorillas don't like it when you do that. it's a type of communication. obviously, the kid didn't understand that. but, she should have been told not to do it. and, so long as you have people making those gestures, the gorillas are going to continue reacting aggressively.
that said, just about any mammal reacts badly to these kinds of living conditions. dogs get mean when you leave them locked up outside. rats actually start eating each other when you put them in conditions like this. and human prisoners go through all kinds of stress and trauma that results in aggressive behaviour.

I agree. Keeping these intelligent animals in such cages is fucking evil. Fuck I hate humans.

+deathtokoalas In the original video, there's a little boy in the background saying something along the lines of "Don't do that, the zoo guy'll come back" I have a feeling that means a zookeeper might have already seen her do it and explained to her once that she shouldn't. But you know how kids can be :/ in one ear and out the other.
