There's no reason to assume that just because a parent is worried about climate change, that their kids will automatically be conscientious. Also, in the future the children of many people who ignored climate change will be forced to care about it.

This comment is full of rationalization. I hear this all the time: Maybe my little darling will be the genius who cures cancer and solves climate change.

Yeah, and maybe you'll win the lottery. But no, your kid will not fix climate change.
