Via IM from son James we have a philosophy professor explaining how environmentalism is a substitute for more traditional religions:

Feeling unworthy is still a large part of Western religious culture, but many people, especially in multicultural urban centers, are less religious. There are still those who believe that God is watching them and judging them, so their feelings of guilt and moral indignation are couched in the traditional theological furniture. But increasing numbers, in the middle and upper classes, identify themselves as being secular or perhaps “spiritual” rather than religious.

Now the secular world still has to make sense out of its own invisible, psychological drama—in particular, its feelings of guilt and indignation. Environmentalism, as a substitute for religion, has come to the rescue. Nietzsche’s argument about an ideal God and guilt can be replicated in a new form: We need a belief in a pristine environment because we need to be cruel to ourselves as inferior beings, and we need that because we have these aggressive instincts that cannot be let out.

Instead of religious sins plaguing our conscience, we now have the transgressions of leaving the water running, leaving the lights on, failing to recycle, and using plastic grocery bags instead of paper. In addition, the righteous pleasures of being more orthodox than your neighbor (in this case being more green) can still be had—the new heresies include failure to compost, or refusal to go organic. Vitriol that used to be reserved for Satan can now be discharged against evil corporate chief executives and drivers of gas-guzzling vehicles. Apocalyptic fear-mongering previously took the shape of repent or burn in hell, but now it is recycle or burn in the ozone hole. In fact, it is interesting the way environmentalism takes on the apocalyptic aspects of the traditional religious narrative. The idea that the end is nigh is quite central to traditional Christianity—it is a jolting wake-up call to get on the righteous path. And we find many environmentalists in a similarly earnest panic about climate change and global warming. There are also high priests of the new religion, with Al Gore (“the Goracle”) playing an especially prophetic role.

We even find parallels in environmentalism of the most extreme, self-flagellating forms of religious guilt. Nietzsche claims that religion has fostered guilt to such neurotic levels that some people feel culpable and apologetic about their very existence. Compare this with extreme conservationists who want to sacrifice themselves for trees and whales. And teachers, like myself, will attest to significant numbers of their students who feel that their cats or whatever are equal to human beings. And not only are members of the next generation egalitarian about all life, but they often feel positively awful about the way that their species has corrupted and defiled the whole beautiful symphony of nature. The planet, they feel, would be better off without us. We are not worthy. In this extreme form, one does not seek to reduce one’s carbon footprint so much as eliminate one’s very being.

It appears many people have a religious gene. They are, in essence, programmed to feel as they do toward “something greater than themselves”. As science made the unknown more knowable and more under the control of man it reduced the domain of possibility and probability of god(s) controlling people’s lives. And people had to have a substitute. This professor proposes environmentalism fulfills this need for many people.

I would like to suggest that an all powerful state fulfills that need for far too many other people–socialism can be thought of as a religion. It is a belief in the goodness of something without, or in spite of, evidence. Compare that to traditional religious faith.

This has serious implications for society and even the entire human race. If we are condemned to believe in things contrary to the facts how can we make the best decisions for ourselves let alone justify the forcing of others to adhere to the will of the majority?
