Monsanto claims genetically-engineered crops are necessary to feed the world and to control weeds and pests. Yet, articles report increasing problems with superweeds and super bugs as a result of herbicides and pesticides used for GMO crops. The infestation of superweeds more than doubled since 2009, according to Dow Chemical, which also states that an estimated 70 million acres of US farmland are infested with pesticide-tolerant weeds that cost roughly $1 billion in damages to crops so far.

According to Science Magazine, “For cotton grown in the South, the cost of using herbicides has climbed from between $50 and $75 per hectare a few years ago to about $370 per hectare today.” The need to apply more and more herbicides makes this practice unsustainable. Science Magazine warns that farmers who rely on the seed and herbicide combo will fail rapidly. "There is no question that GE technology will continue to drive up the costs of food production, increase the use of harmful chemicals and undermine efforts for a sustainable food system. We as citizens need the right to choose if we want to support this disaster scenario."

Nearly Half of All US Farms Now Have Superweeds says: In a 2012 study, Iowa State University researchers found that if farmers simply diversified their crop rotations, which typically consist of corn one year and soy the next, year after year, to include a "small grain" crop (e.g. oats) as well as offseason cover crops, weeds (including Roundup-resistant ones) can be suppressed with dramatically less fertilizer use—a factor of between 6 and 10 less. And much less herbicide means much less poison entering streams.... So, despite what the seed giants and the conventional weed specialists insist, there are other ways to respond to the accelerating scourge of "superweeds" than throwing more—and ever-more toxic—chemicals at them.
