Jacob McDaniels, You are cherry picking numbers to try to support your claim that "tens of millions" more acres are in production than there were 20 years ago.  The acreage for specific crops has fluctuated, but total acreage has remained stable.  See page 12 of the following USDA report:  http://usda.mannlib.cornell.edu/usda/current/htrcp/htrcp-04-14-2016.pdf

Furthermore, your comment to me refers to "your graph on yield, hectograms per hectare."  However, I presented no such graph.  Moreover, no such graph appears in the article.  You might check on the data that you are commenting on.

You are trying to snipe at marginal issues because, apparently, you don't have the data to contradict the main assertions of the article, that GMO crops don't increase yields and that GMO crops have increased the use of herbicides.
