The entire industry employs a great number of people. It’s not so simple to just ban all fossil fuels (even if it is what we need to do) and leave millions out of work. Think of how many industries rely on fossil fuels as well, just to move things or people around. All those jobs go bye-bye overnight too.
I’m not saying we shouldn’t ban fossil fuels, but the fallout from doing so needs to be addressed before it becomes a problem in the first place.
