I think the problem we got is that we need cars, motorbikes for getting to work, shopping etc. If we can just stop everyone using Aircraft for holidays, we will be on the road to being green. This does not mean no more holidays, it just means a new mine set, using the Channel tunnel/cars. Of course Aus, NZ, USA etc has to be off the cards
But go back 60 odd years and we didn't have the chance to go anyway. If you want to see what it looks line, Google/Bing it!
