Capitalism vs Environmentalism 1

Unfortunately with the demise of communism, the only system left standing is capitalism. That gives the impression that capitalism is the better economic model. Part of the problem with this is that capitalism has within its nature the seed of its own (and our) destruction: continual growth in a closed system. It is not possible and only leads to eventual ruin. What is missing is an Adam Smith or a Karl Marx who can articulate a DIFFERENT system that does not lead to ultimate exhaustion of resources and destruction of a human-friendly environment. It's not enough to be "against". What is missing is the clear vision of what to be "for".
