Genetic diversity is the best guarantee against famine. Remember the Irish potato famine? A blight affected the single strain of potato the Irish were growing. Large agribusinesses also practice monoculture for reasons of scale, conformity and economy. With the disappearance of small family farms, many genetic strains will go extinct, because the large corporations will not maintain them. The seeds locked away in some remote arctic vault will not germinate forever.

That's the only part of the anti-GM argument I agree with.
