We do not understand all the causes of cancer but we treat the symptoms and try to minimise the risk of its occurrence, for example, by modifying our diet or behaviour. We need to do something similar with regard to Climate Change.
Ellis - not understanding something and attempting to solve it has the potential to be a recipe for a TOTAL disaster. As an example, very well meaning (but fundamentally flawed) moves to reduce CO2 emmissions by encouraging growth in biofuels is now clearly having a serious negative impact on remaining rainforests. In our panic to solve what may turn out to be a non-existent problem, we are genuinely destroying our environment. I live on Borneo and it is heartbreaking to see the complete destruction of virgin forest by replacement with mile after mile of palm oil plantation. It is is a tragedy or untold proportions. And all encouraged by highly educated, well meaning people who live far away and dream of saving the planet ... but who don't know what they are talking about. This is complex and you need to understand it before taking action.
