The Copenhagen Zoo was already notorious for killing a healthy young giraffe, Marius, in February. Now it has killed four lions, two adults and their two cubs.
The Copenhagen Zoo says the new male will breed with two of its female lions. It claims that putting down the two older lions was the "professionally correct" thing to do because of the "natural structure and behavior" of a pride of lions. The cubs had to be killed because, with their parents gone, the Zoo says they would have been killed by the new male lion "as soon as he got the chance."
In the U.S., zoos use contraception to prevent inbreeding and overpopulation among their animals. European zoos say they prefer to let animals reproduce naturally, as they would in the wild. But living in a zoo is the furthest thing from being in a natural environment. Zoos need to adopt humane polices that recognize this.
