Meh, pandas are cool, but if they'd die without human intervention, they don't really serve a purpose, unless we could eat em. I say, document them, make up some virtual library devoted to them, take blood samples to keep on record, and let em pass. If we aren't all killed by nuclear war, global warming, or the second coming of Christ, then eventually we'll be able to clone them successfully enough to make them a cuter version of cattle... Fir and burgers at the same time!
I think I might be evil!
