Sophable - I (and Aloha and Uwila) have always argued that we should be doing things - that our way of life is unsustainable. I've even put forward a few of things that we could do (and which I am doing myself - although I'm not personally doing the wind and renewable energy! ).
I am just not convinced that hanging it all on global warming is the right way about it. I have a fear that that approach could backfire.
We should be changing our lifestules, and teaching our kids to use resources resonsible because not being prfligate is the right thing to do.
John Simpson recently wrote a lovely article about a couple who recycled everything, didn't have a car, walked or used public transport, only bought something new when the old thing was worn out, put jumpers on when it got cold rather than turned up the heating, grew vegetables.... in short, had a tiny "carbon footprint". Turned out he was talking about his own parents.
I'm not suggesting we turn back the clock to the mid 50s or whenever - rather it is our general attidudes to consumption that need to change.
If it weren't global warming, we'd be f*cking up the planet in some other way.
I actually have a sneaking admiration for the Gaia Principle - that the Earth is a self regulating organism, that will tend towards balance - over timescales we can't imagine. If Man threatens it, well, she'll just "shrug" us off.
