Hi All,
A good topic to discuss. I saw "Interstellar" last week with a few mates from WSAAG, and the topic was relevant.
I've considered the Greenie position fairly solidly, and in its milder forms it has merit. In its more extreme forms, it amounts to suicide (anything a human can do will be bad, so the best thing we can do is not do anything - which equals "Kill yourself and save Nature").
I am pretty solidly set on the idea that we should not die with our planet; that we have acquired the ability to propagate and our future is off-planet.
Terraforming Mars is a good idea - if we can do it reasonably well. I am not sure that it can be done well, because there are a few items lacking there (e.g. water content is minimal, oxygen pressure is really low, gravity is too weak to hold all the atmosphere we'd need).
But engineering a way past these obstacles is a very worthwhile task. We are due for another global extinction event (they apparently occur every 65 million years or so), and having some way to continue past that is a very good idea.
Regards,
Tony Barry
