The reason you can keep a wild animal in a zoo without it constantly trying to jump out and murder visitors is that most animals are territorial. They are enclosed in a space that they can call their own, and as long as those borders are respected, they are happy to eat, frolic and mate for the entertainment of gawking onlookers.
"Step on the white tile. See what happens."
But that territorial bubble was popped by a 3-year-old boy at the Brookfield Zoo in Illinois -- he was right over the gorilla enclosure when he fell over the fence. The 18-foot drop left him unconscious and with a critical head injury. Since gorillas can be dangerously persnickety with their territory, the police were barred from immediate action -- who wants to see a violent battle between a SWAT team and a huge herd of gorillas? Except everyone?
So, with a child in need and no help in sight, Binti Jua stepped in. And as much as that sounds like Indian Superman, it wasn't. Binti just happened to be one of the zoo's gorillas.
