Coal, and the entire fossil fuel indsutry, is certainly something that the young generation of today will have to deal with in the future. The supplies will only last a few more generations. The atmopshere will last even less time than that if we actually burn everything we have in reserve.
I work with a growing internationa movement of students who are working with their college endowments to divest from all fossil fuels. We believe that divestment is one "tool in the tool-box" for working towards climate justice.
Check out more of the movement at http://gofossilfree.org and http://studentsdivest.org. We don't beleive divestment is the "be-all-end-all," but rather that it is a solidarity tool for a generally priviledged student population to work together with groups who are and have been creating climate justice. Lets start educating ourselves, each other, and our youth on the problems of the fossil fuel indsutry. There is no need to demonize, rather a need to put our money into an economic system which is also productive for the planet, rather than destructive.
