Counterargument: Farmers harvest about 2.7 million corn stalks per half year. So 6 months. Again, it would cost $150 more per corn stalk to produce GMO corn. If you multiply 2.7 million by $150, it would then cost $810,000,000 per year. If farmers saved 15 billion dollars over the time GMOs were invented, this would be all the GMO plants combines. But the $810,000,000 is only for the corn per year.. All the other GMO products might even cost more per year.
