Question: if global warming was to go on how long would it take the polar ice caps to melt and destroy our eco system and what steps can we take to reduce this in our day to day lives?

That is a great question. And to be honest I don’t know. First, there is scientific evidence for global warming and there is no way to deny it. Now does that mean that for the first time in human history we are responsible for accelerated global warming? Maybe. The science behind this is not easy as we are dealing with a complex system.

I am not sure that we have to take day-day action to prevent global warming, but I give you one example that strikes me as curious. Every day I drive through Nairobi and for sure I will be behind a matatu that is fuming black smoke out of its exhaust. I can ask myself a fundamental question: is the stinking matatu bad for global warming, bad for driving in peace or bad for my health? I guess it’s all three. Global warming however is a compounded effect over many many things, coal in China and India, farting cows (you didn’t know?) and also Matatus in Nairobi. So my take, I’m against fumes because of my health. That is something I can argue about with scientific facts and that’s what we should change.
