I feel very bad for your friend and I know that some businesses have a different way of operating.
Monsanto sells their glyphosate resistant seeds and then farmers can use glyphosate on their crops. There were instances where other farmers started using glyphosate on their own farms without knowing that their fields was not resistant. Then they blamed glyphosate and Monsanto for ruining their crops. In other cases, GMO farmers used the wrong equipment to pulverize glyphosate and it got in the nearby fields, destroying them.
I mostly agree with you, as greed is a hard feeling to overcome. But rather than dying of undernourishment or starving, I would like to believe that people would use the GMO's. I would use GMO's if the European Union wouldn't ban it. Some say they are banning it to limit imports from US and promote local farmers by using the scientific debate that is going on now as an excuse..
