"And for instance, something like climate change and this anthropogenic mass extinction that we're seeing going on, and we're losing enormous fractions of our biodiversity with every passing year. That's bleak. And it does feel like the end of the world is upon us. And we're entering into an unsurvivable planet. And it's okay to know that and to think that and to still strive for something because I think at its extremes, hope becomes insane. And you have to do something to fight it because otherwise, we are going into the apocalypse, I think there's no question. And to preserve hope against that possibility, I think that's difficult. And so that's what I strive to do."
