Imagine an alien species comes here and sees all this totally fucked up human centric thinking. They put fish in small fish bowls, for their own enjoyment. They deform trees for their own enjoyment... and the list goes on. Bleh.

I assure you, any species capable of interstellar travel will have a capacity and willingness to bend their environment to their will that absolutely dwarfs our own.

Why do you think they would be so bothered by what humans do, when the same kind of thing is done across the animal world? Read about ants milking aphids, for instance.
