"American farmers¹ broad use of the weedkiller glyphosphate ‹
particularly Roundup, which was originally made by Monsanto ‹ has led to
the rapid growth in recent years of herbicide-resistant weeds. To fight
them, farmers are being forced to spray fields with more toxic
herbicides, pull weeds by hand and return to more labor-intensive
methods like regular plowing.

What should farmers do about these superweeds? What does the problem
mean for agriculture in the U.S.? Will it temper American agriculture¹s
enthusiasm for genetically modified crops that are engineered to survive
spraying with Roundup?"
