Bill Monroe 82, You say, "the author...tried to compare measurements with two different units without converting them to be comparable."  However, such a conversion would only serve to unnecessarily complicate things when comparing changes in herbicide use and changes in crop yield, the major points of the report.  For example, the report claims that herbicide use in the US has increased, whereas herbicide use in France has decreased.  There is no need to make any conversions for this comparison.  Also, there is no need to make any conversion to make the calculations that conclude that there has been no increase in crop yield in the US due to GMOs.  (continued)
