Stewart has an article in the current issue of Technology Review in which he claims to be presenting "Environmental Heresies":
Over the next ten years, I predict, the mainstream of the environmental movement will reverse its opinion and activism in four major areas: population growth, urbanization, genetically engineered organisms, and nuclear power.
Dave Roberts at Gristmill has the best take on the article, and I more or less agree with his reaction. But I would add: Stewart seems to be railing against the version of the environmental movement with which he was familiar decades past.
Recognition of the environmental advantages to urbanization isn't a new phenomenon, and the Erlich-style hysteria over population was generally discarded long ago. Even the still-widespread resistance to GMOs and nuclear power usually has more to do with an educated opposition to how these technologies have been deployed (and the lack of oversight and out-and-out deception often involved) than some kind of knee-jerk "science bad" mantra. I'm not saying that the 1970s hippy treehugger caricatures with which Stewart may be most familiar no longer exist, but they certainly no longer represent the bulk of environmentalist thinking.
