Changes

There is now an attempt to verify worldwide how bad the problem of herbicide resistance has become. WeedScience documents (so far) "317 323 Resistant Biotypes, 183 187 Species (110 112 dicots and 73 75 monocots) and over 290300,000 fields" [http://www.weedscience.org/] [http://www.farmassist.com/resistance/] [http://www.plantprotection.org/HRAC/]. Most of the resistances here are due to herbicide overuse in general however because those weeds tolerant of Roundup are closely associated with our food supply and the because of the ''ubiquity'' of Roundup Ready crops they are a particular concern. According to Monsanto the 2007 worldwide total of their GM crops are 234-242 million acres [http://www.monsanto.com/pdf/pubs/2007/Q32007Acreage.pdf].
