No doubt that pollution has caused some kind of effect on weather patterns (we have got 2 inches of snow in the middle spring!) but it is no point the FIA imposing top many green sanctions because until china, india, russia etc. fall in line with green treaty's. Making F1 green will have minimal if no impact on the state of global warming.
Even if the world does implement various green measures to cut down on carbon emissions, we will still have a reasonable amount of carbon dioxide etc. going into the air. This is the 21st century, so we can't turn back the clock hundreds of years and emit negligible amounts of carbon. In that case, motor sport still would not be producing significant amounts of carbon relative to the bigger picture, as it were, (and I suppose this could be extended to non-renewable forms of energy (i.e. petrol), so I still think Formula One and other well-known brands of motor sport could be preserved. The role model effect has a lot of truth at the minute, I'll admit, but I think people should be made aware, as I said before, there is difference between the trappings of change and the substance of change. (Also, much bigger role models come in the form of governments and huge companies. At the minute, as I also said, we're getting taken for a ride in Britain when it comes to climate change; the whole process is being used to raise extra taxes for governments and profits for big business; none of the green charges are being used on green issues. I also don't see too many governments being as eager to deal with other pressing environmental matters that aren't quite so lucrative. How is that just and an incentive to green?)
