Clean air is a basic right. The responsibility to ensure that falls to Congress and the president.
I had the good fortune to be able to right an injustice that I thought was being heaped on young people by lowering the voting age, where you had young people that were old enough to die in Vietnam but not old enough to vote for their members of Congress that sent them there.
I grew up in the '80s where there's a lot of these kind of post-apocalyptic, post-comet, post-whatever it was, so that always captured my imagination a lot as a little kid, that idea of getting access to secret places and being able to roam around where you're not supposed to.
