Recently, DuPont posted the advertisement below for its PHB71 Hybrid Rice grown in Viet Nam. Hybrid rice is cross-breeding of rice strains, not genetically modified as in artificially modifying them. Think of cross-breeding dogs and genetically created dogs, if you want to better understand the difference. We do the former all the time. The latter is a bit more expensive and sketchy… and probably illegal in many countries.
What I found amazing was how these Vietnamese farmers grew rice in the paddies in one season, then harvested shrimp in the same paddies in another! Talk about making use of the land!
