Genetically engineered crops harm the environment by increasing pesticide use, creating pesticide resistant superweeds and contaminating conventional and organic crops. Earthjustice is challenging the USDA’s decision to allow genetically engineered sugar beets and alfalfa onto the market.
Pesticide Policy Expert Charles Benbrook: "The first fully resistant weeds to Roundup started showing up around 2001 and 2002, but by about 2005 the problem really had started to take off, particularly in the Southeast …"
Glyphosate, the main ingredient in Monsanto's Roundup herbicide, has spawned a new generation of superweeds that are spreading rapidly across the United States.
Since farmers planting Monsanto's genetically engineered Roundup Ready crops no longer need to worry about overdosing their crops with herbicide, they tend to spray more of it. And just as antibiotic overuse has resulted in antibiotic resistant drugs, constant use of Roundup and its active ingredient, glyphosate, has given rise to an epidemic of glyphosate resistant superweeds.
