Biodiversity, already decaying fast as a result of climate change and intensive farming, is under further threat by genetic modification (GM) of seeds, says a leading German ecological activist. Genetic modification of seeds is dangerous, ”since it is at the beginning of the agricultural chain, and can spread all over,” says Benedikt Haerlin, former campaign manager at the environmental organisation Greenpeace and former member of the European Parliament. Haerlin now leads the global ’Save our Seeds’ campaign in cooperation with some 300 environmental organisations across Europe.
