According to
this article, GMO's may be the only way we can continue to feed the planet. The piece begins by talking about flood resistant rice. A field in Uttar Pradesh, India, was planted with the genetically modified crop, and even though there were floods, "Instead of drowning, Mr Pal’s rice sprang back when the water receded. In a normal year he gets a tonne or so from his 1-hectare (2.5-acre) plot; in a bad year nothing. In that terrible flooded season, he harvested 4.5 tonnes—as good a yield as on any rain-fed paddy in the world." Pretty hard for me to look that guy in the eye and tell him these cultivars are somehow bad.
