Some anti-GMO activists, including Indian scientist and organic-farming champion Vandana Shiva, have blamed the high suicide rates directly on biotech seeds - specifically, cotton tweaked by Monsanto to contain the Bt pesticide, now used on more than 90 percent of India's cotton acreage. Shiva has gone so far as to declare them "seeds of suicide," because, she claims, "suicides increased after Bt cotton was introduced."
