Over the years as we have read about the inevitable decline in the reserves of fossil fuels, we have been"comforted" to learn that at least we won't run out of coal for a long time.
Now we realize that this was false hope. If we are to protect the biosphere so as to minimize the extinction of species and maintain the climate and oceans in conditions which are at least tolerable to humans, if not ideal, then almost all of this coal must be left in the ground.
A good place to start would be the bankruptcy of Peabody Coal. Let's get on board with that. A secondary but essential follow-up is to shut down tar sands extraction.
A path to these worthy goals is a tax on carbon mines. The revenues would be equally distributed to all U.S. and/or Canadian citizens.
