How, though, can we get governments, particularly in the biggest polluting countries, to play their part?
To be honest Musicgirl, I don't think its a valid question. As long as we keep asking that, certain groups have an excuse for saying that its not worth us doing anything, because "China". Also, people don't seem to want to hear that China are the world's leader in renewable technologies, but that that is the case. China have realised that the future is renewables, and they are doing something about it.
So while we faff around and open new oilfields, China (and the others) are investing in the Green future.
We all feel in this country that we individually have to do something, and most of us do. But we have to put pressure on our own government to do more. Which means not making fun of the Green Lobby and the people who glue themselves to roads, extreme though they are. (I know you don't do that!). Votes count.
