Greenpeace has called for a ban on all genetically engineered crop field trials in Australia, saying the science is not fully understood. While genetically modified cotton and canola have already been released commercially, there are a range of other GM plants growing in field experiments around the country including wheat, barley, bananas and sugarcane. ”We’re fine with GM research in the lab, but Greenpeace believes we just don’t know enough when it comes to genome function to support the release of a living genetically modified organism into the environment,” Greenpeace spokeswoman Laura Kelly said.
