Michael J. Coren warns that Monsanto’s Roundup was supposed to make it easy for farmers to get rid of weeds, but it’s working on fewer and fewer plants, including some monsters that can grow three inches a day and destroy farm equipment, for Fast Company:

For decades, farmers had it relatively easy when it came to weeds infesting their soil: apply herbicides, wait for the weeds to die and grow more crops. Those salad days, alas, are coming to an end.
A new series of studies released by Weed Science this month finds at least 21 weed species have become resistant to the popular herbicide glyphosate (sold as Monsanto’s Roundup), and a growing number survive multiple herbicides, so-called “super-weeds.” The same selection pressure creating bacteria resistant to multiple antibiotics is leading to the rapid evolution of plants that survive modern herbicides. If the trend continues, yields could drop and food costs climb as weeds grow more difficult to uproot.
