I'm sure our civilisation - as we know it - is doomed!
There's not the political will or appetite for the radical changes needed...it would be a vote loser, and political suicide and all that.
This is where democracy doesn't work.
If the world was ruled by totalitarian hard men, then something could be done.
But, at the moment, no one - or nowhere near enough - is going to give up their cars, change their diet, stop flying all over the planet, give up their gadgets and so on.
Of course, when the extremes of climate change really start kicking in, maybe the public appetite for the required radical steps will be forthcoming...if it's not too late by then!
