That was heartbreaking. I know there are all kinds of practical reasons, but I just kept thinking while watching it, "WHY DOESN'T THAT REPORTER STOP TALKING AND FEED THOSE ANIMALS." Erg.
My second-grade teacher told my class a similar story about the elephants in the London zoo during one of the world wars. There were bombs falling all over the place, and people were worried about what would happen if a bomb fell on the zoo, simultaneously freeing the animals and terrifying them. In order to avoid the possibility of that happening and scared elephants trampling people, the zookeepers slowly starved the elephants. Another heartbreaking story. It's stayed with me all these years.
