Can't be bothered with strafer's words. Guess he's naive
If you'd have been around 200 years ago, I guess you'd have been one of those convinced that people's heads would fall off once they went faster than 20mph on the new fangled steam trains.
You are the naive one my son, prepared to believe any old tosh designed to take more of your money.
So, I'll repeat again, while global warming is a fact, the idea that's it's caused by nasty 4x4s is laughable. The simple fact is the eruption on Mt St Helens a few years back put more CO2 in the atmosphere than mankind (boo!, hiss!) has managed in his entire existance.
Educate yourself.
