Yes, I believe it is. Economics works, just like Maja mentioned. If you have a choice, you just have to price it correctly. What's the environmental impact? Then you have to price it properly. We know incentives work. They work everywhere. They work in our personal lives. In my life, they work with my kids, and in work. If you incentivize a job, it's going to be done and it's going to be done well.
I don't personally believe in a ban. It's like a stick versus a carrot, and it has been proven that a carrot works better than a stick.
