A Greenpeace activist displays signs symbolising genetically modified maize crops during a protest in front of the European Union headquarters in Brussels November 24, 2008. As ingrained as GM crops may seem in parts of the world, a backlash against the technology appears to be growing. Opposition to genetic modification of seeds has long been strongest in Europe. The European Union severely restricts use of GM seeds on its territory, as well as imports of products containing GM-derived food. Now consumer resistance to what British tabloids long ago dubbed "Frankenfood" is taking root in the United States too. Picture taken November 24, 2008. To match Special Report FOOD.
