THE Australian Greens say they won't give the green light to Genetically Modified crops – or any other version of GM's – despite widespread support for biotechnology amongst Australian farming groups and the scientific community. Leading farm groups and plant scientists back GM technology development, with its potential to generate varieties with drought and even frost tolerance, or grow in soils where virtually nothing exists. Citing feedback from her ”listening tour” of regional Australia, launched when she replaced Bob Brown in April, Australian Greens leader Senator Christine Milne said she was ”reinforced in the view” about not allowing GM's in food chains.
