I don't think defending Ukraine's democracy from an obvious authoritarian invader is silly. It wouldn't be silly if it was your house being blown up for no good reason or your kids/wife getting kidnaped/raped/tortured/killed. What's the point in climate action if not to save human life? You just worried about the fish?

Climate change sucks, but if we give up all our morality just to fight climate change than why bother? You want to let all the rapist and murders free because that distract from climate action also?

If humans can't multi-task then it's just time for us to go. If we can't have reasonable law and order and basic morality AND fight climate change, just smoke em while you got em because the species isn't worth saving.
