In fact, the Roundup Ready System was specifically ''designed'' to require the exclusive use of Monsanto's herbicide, Roundup, primarily, some say, to increase profits for Monsanto - and at almost 250 million GM acres worldwide which all require Roundup that's a lot of profit [http://www.purefood.org/mothjones.html]. Says David Ehrenfield, Professor of Biology at Rutgers University, "Genetic Engineering is often justified as a human technology, one that feeds more people with better food. Nothing could be further from the truth. With very few exceptions, the whole point of genetic engineering is to increase sales of chemicals and bio-engineered products to dependent farmers" [http://www.mercola.com/2002/nov/2/biotechnology3.htm]. ''"In the United States, the widespread adoption of Roundup Ready crops combined with the emergence of glyphosate-resistant weeds has driven a more than 15-fold increase in the use of glyphosate on major field crops from 1994 to 2005"'' [http://www.foei.org/en/publications/pdfs/gmcrops2008full.pdf].
The draw for farmers is the promised reduced cost, and increased yield and thus extra profit over traditional systems. Says this Monsanto blurb "no-till soybeans grown in narrow rows add $16 per acre more to a grower's bottom line than conventional soybeans.... On a 1,000 acre farm, no-till can save as much as 450 hours of time and 3,500 gallons of diesel fuel each year. That's 11, 40-hour weeks in time savings and $4,000 less for diesel at $1.15 per gallon" [http://southeastfarmpress.com/mag/farming_monsanto_guarantee_roundup/]. However the weed control advantage of the no-till vs. conventional system has been disputed [http://web.archive.org/web/20041018161535/http://www.gov.mb.ca/agriculture/crops/weeds/weedfacts/fba03s00.html].
