Well, you simply can't stop one and just hope starting on the other will fix all your problems. A gradually transition from one to the other is what's needed.

Well, you simply can't stop one and just hope starting on the other will fix all your problems. A gradually transition from one to the other is what's needed. I remember in college my professor was telling me about villages in Siberia where they mined asbestos. Even decades after every industrialized country had stopped using it, they were still mining it since it was the only way the village could survive. Sometimes survival is more important then saving the environment to some people.
