I don't really think he's talking 6-7 billion people either - but I think it needs to be pointed out.... because people tend to think it would include them. No it won't.
Even so, doing this for a couple of thousand people, "the select few", would take hellish amounts of effort and money - and if you are going to do all that, then its much better to work on ending the problem. jon ________________________________ From: [email protected] <[email protected]> on behalf of Greg Rau <[email protected]> Sent: Saturday, 6 May 2017 1:17 PM To: [email protected] Subject: Re: [geo] Plan C 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 https://en.wikipedia.org/wiki/Rapture Anyway, we've transcended geoengineering, but what the heck it's Friday.

Much easier to stop using coal, build asteroid defense units.... etc.... jon ________________________________________ From: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> on behalf of Greg Rau <[email protected]<mailto:[email protected]>> Sent: Saturday, 6 May 2017 10:22 AM To: [email protected]<mailto:[email protected]> Subject: [geo] Plan C http://www.bbc.co.uk/mediacentre/mediapacks/tomorrows-world/television "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.
