It was good to hear the other side of the global warming argument.

I get sick of the middle class harping on about GW, yet still driving their people carriers everywhere, and most'greenies' I know are always flying off somewhere around the world.

They'll make a lot of noise about recycling everything and going to the farmers' market rather than Tescos but won't actually sacrifice anything that will impact on their quality of life.

There are other more pertinent environmental issues. Fossil fuels won't last forever. We need to be more aware of using up vital resources and irrevocably polluting our incredible planet.

But I'm not convinced that making tokenistic sacrifies to our way of life will halt global warming - if it's our 'fault' in the first place.
