This essay, written on the foundation of Objectivist philosophy and procapitalist economic theory, is the most powerful and convincing critique of environmentalism available. From “intrinsic value” to “global warming,” it exposes the rampant errors and contradictions of the movement and shows its profound hatred of human values. It demonstrates why the real problem of the industrialized world is not “environmental pollution” but philosophical corruption, of which environmentalism, with its hatred of science and technology, is the leading contemporary manifestation. The essay concludes with a call for a cleanup of the environment—the philosophical-intellectual environment—based on the introduction of the writings of Ayn Rand and Ludwig von Mises into college and university curricula.
