They just have nothing better to do. Kinda like Green Peace and those tree hugging environmentalists ;)

I heard of a Japanese boat called the Whale Kill and Green Peace wanted them to change the name. Whale Kill is a Japanese name, not meant to advocate the killing of whales. I mean, I know it was a whaling ship but still ;)

PETA is an extremist group and I rarely agree with extremists on any issue, so I'll preface by saying by and large I think they are doing more harm than good for the cause and I don't generally support them.

But people have no business owning wild animals, especially animals as strong, intelligent, and willful as chimpanzees. It is practically an inevitability that someone treating a chimpanzee like a child or a puppy is going to get hurt. The victim (who was not even the chimp's owner) didn't at all deserve to be injured, and more people might have been hurt if the chimp hadn't been shot, but when a wild animal acts like a wild animal, who is to blame? The animal, or the person who attempted to keep the animal such an unsafe way? The same principles apply to the whale's situation. Animals were not put on this earth solely to serve people in any way, whether as food, entertainment, or decoration. We certainly have the intelligence and technology to use them that way, but we also have the compassion and empathy to understand that they are capable of suffering as well. We can raise an animals for their products without putting them through a torturous life and painful, prolonged death, and we can learn to respect that nature cannot be and should not be completely subjugated.
