Noted: These true believers come as a flood of new gene crops approaches. The European Union estimates the number of GM traits in crops will quadruple to 120 by 2015. Only half will be made by for-profit companies. Stewart Brand, one of the founders of the back-to-the-land movement, has been arguing fiercely that environmentalists need to drop their anti-GM stance. So has Karl Haro von Mogel, a 27-year-old plant sciences graduate student at the University of Wisconsin at Madison, whose blog promotes the technology. “Thereâ??s so much stuff going on that nobody even knows about,” says Von Mogel. “There is this huge potential if we use the science to pursue those things that are possible.”
