Come to think of it, Monsanto wants farmers to waste money on using RoundUp. The best way to do so is to make the farmers spray more and more RoundUp all over the fields with no effect on the crops. If the corn crops are resistant to this stuff, farmers will definitely spray more RoundUp than they need. It's the herbicide equivalent of tossing the baby with the bathwater. If the weeds are herbicide-resistant because of this genetic modification crap, then Monsanto can "unveil" the latest kind of weed-killers and sell that stuff to the farmers along with new plants that are resistant to this new herbicide stuff...
