The two technologies most reliably and stridently opposed by the environmental movement — genetic modification and fracking — have been the two technologies that most reliably cut carbon emissions.—Making batteries for electric cars is a dirty process, and if the electric cars are run off a grid which is primarily powered by coal, as it is in China, the environmental benefits completely disappear. Green jobs, green energy, green cars: the record of green public policy is far more problematic than most environmentalists are willing to acknowledge. Like the “peace activists” of the 1930s whose foolish policies helped Hitler stage a bid for global mastery by disarming the democracies, green activists today are often doing more harm than good.
