Ecologically-minded Christians need not take offense, but there is a definite correlation between Biblical teachings and arrogance, or at least indifference, toward nature. Creationists and others who take the following passage literally cannot be expected to see Man (in evolutionary terms) as part of a larger whole.
"And God blessed them, and God said unto them, be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth." (Genesis 1:28)
The above is interpreted in different ways by different people, but it clearly states that Man's will is far more important than the status of other life-forms. Thus, it's no surprise that many fundamentalists are not keen on protecting species or wilderness that stands in the way of human expansion. Probably 90% of anti-environmentalists are religious and they give more credence to a 2,000 year-old book than all the scientific evidence of human impact.
This excerpt (RealAudio/MP3) from a caller to the Michael Reagan talk-show sums up the mindset. Note his blind assumption of a pre-ordained depletion schedule. If God is such a great supplies manager, why is anyone starving? Are Man-made extinctions just a case of purging old inventory? It's fitting that the caller is from Las Vegas, home of extreme carrying-capacity overload.
Even if they do acknowledge Man's role in environmental problems, Creationists claim that God will be the final judge, conveniently deflecting any logical arguments. Former Interior Secretary James Watt was a prime example of this myopia, with his belief that rapid resource consumption was justified because the religious concept of Armageddon would render everything moot. If you have any doubts about the connection, read the beginning of the environment-chapter in Rush Limbaugh's first book, "The Way Things Ought To Be."
Since many fundamentalists are unable to see Man's impact as detrimental, they falsely conclude that environmentalists can only be motivated by evil desires to control the human race (i.e. socialism). When you hear speeches about the evils of environmentalism, misguided religious beliefs are usually involved. Ask hard questions of these people and ye shall find.
