I wasn't talking about the solution, just the reasons.
But if we talk about solutions, for one, the world doesn't have to stop producing CO2, there are advanced methods to store it underground in rocks perfectly safe. There are more than one way to deal with it en mass, the technology is ready.
One electric car won't make a difference, but when there are many electric cars like in Norway, that does. When most cars will run on green energy, that will be the ideal, but i guess, one step at a time. Now they sell more new electric cars there than regular ones. That's an extreme example and not many country can pull this stunt off, but they did it.
Gasoline is piss cheap in such a developed country as the US, still, Tesla is outperforming traditional car manufacturers, when it comes to new car sales. And this happened in a matter of years. Something has definitely started.
Climate change is a complex issue. In the US transportation is responsible for around 30% of greenhouse gases produced by man, around 3/4 of that is coming from cars. You see, even if every car would be electric from tomorrow, that would mean only 20% less greenhouse gas emmission, which is not a too big number and won't happen, but every little percentage counts.
Switching to electric cars is not the most important thing to do, cars are not the main culprit, but a start.
Everything starts in the head. If everyone thinks like you, nothing will change, if more and more people start to think different than you, that's when increasing trends can slow down or even change.
