Brazil: more GE crops, more pesticides
Since 2008, Brazil has held the dubious distinction of spending more on pesticides than anyplace else on earth. But what has the country's farmers, public health professionals and environmental advocates even more worried is Brazil's corresponding rise in planting of genetically engineered (GE) crops, engineered to tolerate mega-doses of herbicides like glyphosate (Roundup). And these crops are driving emergence of herbicide-tolerant "superweeds".
