Greenpeace protests against the tests on genetically modified (GM) wheat conducted by the Technical University of Switzerland (ETH) and the University of Zurich on a field in Zurich-Reckenholz.

Greenpeace activists place warning signs with the biohazard symbol and the slogan: "Achtung Gentech Zone!" or translated: "Caution: GE-Zone!" at the fence surrounding a field where the Technical University of Switzerland (ETH) and the University of Zurich have sowed genetically modified (GM) wheat the day before.
