SF Environmental Policy Examiner: Making a difference on global warming

We would be healthier people if we moved from coal to either natural gas or nuclear power. [Would we?] It makes sense to do this no matter what our opinions are on global warming. A sane and sensible plan to convert to cleaner power generation over time would be good for our country and our planet even if we were heading into an Ice Age. One way of encouraging this transformation is by assigning a price to the polluting aspects of using coal and making the polluter pay this price.

I don't understand why people don't acknowledge this.
