Earth is Tipping Because of Climate Change

It's sort of like an old house that has issues with the piping, vents, and mold may have overtaken the basement. You can chose to abandon the house or put on your game face and work out solutions to fix up the house. If you're smart you can triple it's value. I don't think a couple structural issues ought to be enough to consider abandonment when the place is totally fixable.

Very possibly. Of course, if that were to happen, would we still be "human" or would we morph into what would effectively be a new species, one better designed for our new home? Would it defeat the purpose of preserving humanity if our new home changed us into something entirely new and different?

My preference remains to preserve the Earth. In fact, for the benefit of the other species with which we share this gorgeous planet, I think we have a duty to protect and preserve it.

I would prefer to preserve this planet as well. However, I think it's logical to seed other worlds with human life if we want to preserve the species. This brings me to your question. I think that, eventually, over a course of hundreds of thousands to millions of years, we would be different enough from current humans to warrant classification as a new species, assuming the environment on new worlds was different enough to drive that evolutionary branch-off from Homo Sapiens Prime. If Earth survived and some humans remained, I'd like to see how the humans who stayed and the ones who migrated to other worlds might compare one million years from now.

I once had an idea for a science fiction novel involving a galaxy populated bu multiple sentient and technologically advanced races, but the galaxy had initially been a lonely one populated by only one spacefaring race. As that race branched out and colonized worlds, the inheritors of those worlds gradually evolved into several unique species over a long period of time. At some point their origin was forgotten and that history lost.

Star Trek TNG suggested a similar origin for all of the humanoid races--that they'd been seeded on planets with the same genetic material by an ancient race of aliens, thus explaining the similarities among the different races on that series.
