if we stop the methane from cows, halt the destruction of the rain forest for timber and other minerals,what will we use to replace the meat lost and the materials needed in the future for a much larger population??why doesnt someone suggest only public bodies (fire police and ambulance) can only use cars and make public transport mandatory, thus removing at a stroke a whole heap of car related crap, from petrol fumes to the very metals they are made of being wasted?why why why oh why? ok they will lose a lot of taxes, but the green taxes will cover that and more besides wont it, oh AND KEEP PARASITIC HIPPIES IN A JOB TOO! (so its not all bad then!)
