The problem isn't that Earth day has had little to no effect but the fact that it perpetuates a fantasy that the current climate crisis can be 'solved' with moderate cool heads, while ignoring the lateness of the hour. Wen Stephenson:
End the dishonesty, the deception. Stop lying to yourselves, and to your children. Stop pretending that the crisis can be “solved,” that the planet can be “saved,” that business more-or-less as usual—what progressives and environmentalists have been doing for forty-odd years and more—is morally or intellectually tenable. Let go of the pretense that “environmentalism” as we know it—virtuous green consumerism, affluent low-carbon localism, head-in-the-sand conservationism, feel-good greenwashed capitalism—comes anywhere near the radical response our situation requires.
So, yeah, I’ve had it with Earth Day—and the culture of progressive green denial it represents.
