My cosmological worldview isn’t so species-centric as to be terriblyconcerned about the planet Earth. When people say we must save theplanet, what they’re really saying is we’ve got to save ourwelves. Theplanet did just fine without us for billions of years. And while it’s awonderfully beautiful place that we really ought to take better careof, it will do just fine without us, too.
But just for the sake of a good debate, what great philosophicalquarrels would be resolved were humans to go the way of the dinosaurs? And in whose favor?
