This is overly simplistic and conspiratory. Yes, Monsanto is evil, but that doesn't mean everyone involved in GMOs is, or that's the only motivation. Look up the argument over golden rice.

It's also ridiculous to just hand wave away crop productivity improvements with "but we already have enough food." We aren't going to revolutionize global food distribution any time soon, but we can do things that have concrete impact right now. We're also losing land to agriculture far too fast, particularly in the amazon. We need to be decreasing the amount of land used by agriculture, and GMOs are a very powerful tool in that interest.

GMOs need to be regulated, and I think the IP regime that Monsanto is protected by should be struct down (not that I expect that any time soon). But please don't wave away the entire discussion with strawman arguments.
