HERE'S AN ARTICLE from the New York Times on growing opposition to nanotechnology from, well, about the people you'd expect it to come from.
Eric Coe has weighed in on the subject. I spent part of my summer writing a fairly lengthy treatment that isn't out yet, but you can read this piece that I published in the Environmental Law Reporter last year for some observations. It's worth noting that Greens are quite split on nanotechnology: Terence McKenna called nanotechnology "the most radical of the green visions," and of course it is, since it promises to make everyone rich without significant environmental harm. Why, if nanotechnology were widely available, there wouldn't be starving people in the Third World, and there wouldn't be environmental messes to complain about. A whole bunch of NGOs and public-interest groups would be out of business.
