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.... jon ________________________________________ From: [email protected] <[email protected]> on behalf of Greg Rau <[email protected]> Sent: Saturday, 6 May 2017 10:22 AM To: [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.
