I'm just recalling some infamous incidents that happened with people at the zoo.
In 2009, a woman at the Berlin Zoo decided to jump into the polar bear exhibit, with the water surrounding it. The woman than wanted to say hi to the polar bears, in which they didn't welcome her positively. They attacked the woman, but luckily, she was saved and no one died. She is out of luck that her stupid actions didn't cost her LIFE, because she would've been putting herself in a death trap.
In 2015, a toddler at the Cleveland Metro Park Zoo fell into a cheetah exhibit, but WHY IS IT? One of his parents held him on the railing that goes below the cheetah exhibit, but the toddler lost his balance and fell 10 feet into the exhibit. Luckily, the cheetahs had no bad plans, so the keepers were safe to retrieve him. A good ending, but, it could've been the Pittsburgh Zoo incident result that hit the child.
In 2016, a woman at the Toronto Zoo lost her hat near the tiger fence, and she jumped in to retrieve her hat. It was a bad idea, since she was right next to the tiger exhibit and could've been attacked. Luckily, the woman wasn't injured, but she crawled up to watch people curse and insult her. No person should jump into a risky spot just to retrieve a small belonging, because you're basically just paying a ticket to get a near-death experience.
I have a story I want to share, but its quite disturbing, so I don't know if I want to share it to the viewers or not.
