Climate Change - Human Extinction

[Yonadav]

If we could get our act together, the human species could last hundreds of millions of years; the dinos did.

It’s not one specie of dinos that lasted hundreds of millions of years.   Rather it is thousands of descendant species of Dinos that each came and went in its own time within those hundred million years, rather like individual bubbles come and go within a persistent head on beer in a glass, that kept the genetic lineages of the original ancesteral ur-dinosaur going all that time.

Even if our descendants are still in existence a hundred million years from now, we as the ur-sapien specie need not ourselves be particularly long lived and avoid extinction for all that hundred million years.   We could emigrate from earth and quickly and prolifically speciation, leading within a few million years to many daughter species of human descendants better adopted to a wider array of environments and technology conditions, while we the original ur-specie either linger or go extinct.    Some of our daughter species would in their turn spectate, but all of them will also go extinct sooner or later but mostly long before the hundred million years is up, leaving our genetic future in the hands of yet more generations of grand daughter species.

 Colonists who don't live environmentally sustainable lives will trash a new world in just a few hundred years.
