The guy on the farm next door is happy killing leopards which threaten his sheep. Leopards are endangered. He doesn't care, in his world view there have always been many Leopards. He has his reasons for wanting to kill leopards, but eventually humans are going to kill them all and that can't be right. Like you, I'm excited by the idea of living longer, but it's selfish. For the world it would be better if we lived even shorter. You'd have a faster churn of ideas. Think of ignorant people consuming ivory or rhino horn out of ignorance. This ignorant generation is going to wipe out these animals outside zoos and tiny protected reserves. Their children would likely be more educated and likely not follow the ignorant behaviour of their parents. But the parents(we) live too long. I'm sure there is an analogue in my appetite for beef and the destruction of the Amazon or my desire to own and drive a fossil fuel driven vehicle.
