Content: We do not have to go into detail about probabilities to assess whether superweeds will form – we already have confirmation that they have. Twenty-four cases of glyphosate-resistant weeds have been reported around the world, 14 of which are in the United States [7]. Farmers are now back to tilling their farmlands and spraying more toxic herbicides in addition to Roundup in an attempt to control the superweeds spreading across their farmlands [8]. Additionally, because many of the superweeds can still be killed by glyphosate if it is sprayed in higher doses, many farmers are spraying more glyphosate and other herbicides to combat the weeds. The attraction is that this is much less labor intensive than plowing and handpicking weeds out of the soil [9]. Consequently, a report drawing from US Department of Agriculture data on pesticide use estimated that an additional 383 million pounds of herbicides have been used than if Roundup Ready crops were never introduced [6]. This increased use of glyphosate heightens the likelihood of higher concentrations of the chemical running off into nearby ecosystems. At these elevated concentrations, glyphosate may be capable of causing environmental damage. Furthermore, the practices of tilling and increased herbicide use are similar to what they were 20 years ago (with even more reported herbicide use). This is both an environmental problem and a financial problem for farmers who must now revert to spending more on herbicides and labor costs to till the land [10].
