Environmental extremism is a breathless handmaiden for collectivism. It pours a layer of smooth, creamy science over a relentless hunger for power. Since the boogeymen of the Green movement threaten the very Earth itself with imminent destruction, the environmentalist feels morally justified in suspending democracy and seizing the liberty of others. Of course we can’t put these matters to a vote! The dimwitted hicks in flyover country can’t understand advanced biochemistry or climate science. They might vote the wrong way, and we can’t risk the consequences! The phantom menaces of the Green movement can only be battled by a mighty central State. Talk of representation, property rights, and even free speech is madness when such a threat towers above the fragile ecosphere, wheezing pollutants and coughing out a stream of dead birds and drowned polar bears. You can see why the advocates of Big Government would eagerly race across a field of sustainable, organic grass to sweep environmentalists into their arms, and spin them around in the ozone-screened sunlight.
There's so much more at the link. I especially commend this essay to the attention of Kate Knuth.
