Calvinism and Environmentalism

Thinking about whether forms of the Calvinist concept of the elect are reappearing in new formations. For example; environmentalism. Environmentalists demonstrate through their consumption choices that they are aware of thier impact on the environment and attempting to ameliorate it. Is this a viable solution to environmental problems, or are they simply driven by guilt over the original sin of being born into a consumptionist society? Do consumption choices serve as a demonstration to themselves and others that they are part of the 'solution' (ie a member of the elect). How does this relate to the doctrines of Protestantism that Weber spoke about in The Protestant Ethic? Is this a middle class phenonmenon? Have old middle class values changed in the face of the 'death of God' and modern preoccupations with the failures of our society?
