Animals getting killed cuz of dumb humans (human error)?

anyone ever notice when a dumb human leaves food around, wild animals come out searching for food and cuz they're venturing into human areas, they are shot and killed? or how about when a zoo employer enters into a big cats cage and is killed by the big cat and the big cat is the one that has to be put down cuz of human error. about when a performer puts his arm into a crocodiles mouth for show and the croc bites it off and the croc gets killed cuz of what he did. god, sometimes i really hate humans.
