Actually as a regular dumb kid, I didn't really give the whole atomic destruction threat that much attention. I assumed I'd grow up and things would work out, which they kind of did. But you're right about climate catastrophe, we can't really stop what has already grown into a huge problem. But maybe we can do more to keep it from getting even worse. Only people shouldn't do nothing on the belief that they'll never "have to grow up and face it." They will grow up, and they will have to face it and more besides.
