Barring some sort of major astrological event, it's somewhat obvious the planet will survive. Even if we have a sixth extinction related to climate and humanity is decimated, in a few million or billion years another asteroid or ice age or volcanic event will reset planet life, if with a little luck some is left. And then sometime the sun will burn out and maybe the planet won't survive and extinction events won't matter. I tend to think more short term quality of human life and a rich and diverse natural world, like maybe for the next seven generations, as it goes.
