Limits was right about the most important limit of all. On “the limits of natural ‘sinks,’ or the Earth’s ability to absorb pollution,” Parenti writes, “the catastrophically bleak vision of Limits is playing out as totally correct. We may find new inputs—more oil or chromium—or invent substitutes, but we have not produced or discovered more natural sinks. The Earth’s capacity to absorb the filthy byproducts of global capitalism’s voracious metabolism is maxing out. That warning has always been the most powerful part of The Limits to Growth.”
