It's not a problem that can be solved at the individual level so I don't worry about it.

Since it's a political problem and I lack power to affect change at that scale I don't worry about it.

By the time it becomes a serious problem I'll hopefully already be dead or die quickly. If I'm somehow still alive then I'll worry about it then. Hopefully my death is painless and free of prolonged suffering.
