I think you're underestimating the change needed to counter or prevent climate change.

Personally I think it's stupid to want to 'prevent' climate change. That's unlikely to even be possible as it's also a natural event. But there are certainly things like over-pollution and burning up of fossil fuels that can be reduced or changed...

But really... I don't see any sign of oil companies even wanting to change their way of making money. I'm sure the consumers will make sure all the oil will be gone before the more serious steps are being made changing to electric or bio-fuel cars.

After all, who's controlling the market? Automobile companies and oil companies and because there are a whole lot of people who drive cars, there will be a huge demand for fuel.

Changing that would mean changing cars of billions of people. That's simply not going to happen before the oil is gone.
