For three decades, environmentalists have been claiming that if we don't do something—and fast—to fight global warming, we'll all turn into pumpkins by
the end of the century or so. Yet they've made very little headway in getting humanity to act on their suggested remedies. Their latest recommendation is that people should have fewer children.
But I note in my morning column at The Week, the problem with all their "solutions" is that they suffer from the collective action problem, namely getting people to make painful sacrifices without knowing if others will follow suit. For example, if some people forgo children but others don't, the former will suffer a deep personal loss and the planet will be no better off. Hence everyone waits for someone else to go first and the "solution" doesn't even get off the ground.
If the environmental movement is serious about addressing climate change, it will have to forget about the fact that humans caused (and are causing) the warming and think of our problem like a meteor strike — a catastrophic event that humanity did not cause but from which it has to be saved. In other words, enviros will have to look for technological fixes that don't depend on the environmental equivalent of Mao's cultural revolution to get people to embrace carbon-free lifestyles.
