I don't think Hawkins is talking 6-7B people, but a select few who could keep
the species going somewhere. Who gets to stay and who gets to go and why ought
to pose a moral dilemma that could keep our ethicist friends busy for years.
I'm not religious, but wouldn't this be like the Rapture

Yes, another problem is that Hawkins forgets how much energy and effort we
would have to expend to get 6-7 billion people to another planet, and for them
to be able to live afterwards
Even getting a couple of thousand people would be a truly enormous effort.
Much easier to stop using coal, build asteroid defense units.... etc....

"Professor Stephen Hawking thinks the human species will have to populate a new
planet within 100 years if it is to survive. With climate change, overdue
asteroid strikes, epidemics and population growth, our own planet is
increasingly precarious."
GR- We refuse to live sustainably on Earth, so let's move? The ultimate moral
hazard - why bother changing behavior if we can simply spread our unsustainable
behavior to other planets? Perhaps one of our ethicist friends would care to
weigh in.
