CLARKSDALE, MS -OCTOBER 19: A cotton boll waits to be harvested on BTC farm October 19, 2003 near Clarksdale Mississippi. BTC raises 1000 acres of cotton, 80% of which is genetically modified (GM) Bt, Roundup Ready cotton. The government mandates at least 20% of the crop is planted with conventional cotton to help prevent insects from developing an immunity to the GM products. BTC plans on planting 100% of its cotton acreage in conventional cotton next year to take advantage of the premium paid by mills. (Photo by Scott Olson/Getty Images)
