Well, we don't know what's going to happen, but we can at least try to save ourselves and our descendants and protect the rights of our relatives. What makes us superior to them?! Bigger brains?! That's all it is really... they are the same as us in every other way. Look, I'm not saying that we should treat them exactly as equals, but what they're doing now is committing genocide against them! Making their species extinct!!!!
Maybe there'll be a huge shift in policy. Just because you own a gun doesn't mean it's going to go off. Right now it's as though there are loaded guns and grenades being handed around by little children, but that might all change.
There could be a major accident at some point and then people might see the error of their ways. There's supposed to be projects underway for sending humans to outer space so that they might live there, grow crops etc. there without depending on earth. Personally I doubt that will happen in our lifetime, but maybe we could survive.
