Environmentalism is, theoretically, a legitimate and moral concern: we should be good stewards of Creation. In reality, however, it is a quasi-religion, and a dark and decadent one at that -- appeals to reason are suspect, if not banished.
You don't believe me? Try telling a dedicated Greenie you don't care to recycle, and step back for the reaction (never mind that recycling is mostly harmful, because it wastes more resources than it recaptures).
In fact, the more fervent environmentalism is a kind of Wagnerian paganism -- paganism because it worships created things; Wagnerian because it is often so gloomy, and often predicts (and seems to look forward to) a cataclysmic Twilight of the rotten human race that has ruined everything!
Well . . . it's just about all rot and garbage, intellectually bankrupt, a kind mental solitary vice (I didn't want to offend you, dear reader, with the "m" word).
Every once in awhile this crowd hits upon a fact or an insight, rather like a blind squirrel finds nuts -- and it's enough to re-energize the religion.
But it's all whacked. Click the headline for another example of why.
