Consumerism in all its guises, is the worlds foremost cause of pollution. How many of us would be willing to rewind our lifestyles and living standards back to pre 1900 levels?

That would be the minimum required to make any impact on co2 levels.
It woulds also mean the end of Capitalism as we know it
Instead of buying our living standards, we would be obliged to become self sufficeint in food production, return to living as three and four generation family groups,sharing in housing, heating and the production of food.

All the talk about alternative energy sources is only a load of "hot air", if these new sources are to be wasted producing items whos only purpose is to encourage people to exchange their lives for money and the money for a consumerist dream...Ake
