This TED talk provides a nice high-level overview of what genetic modification is, how it can benefit humanity and helps to dispel some of the fears surrounding GMO's.

Pamela Ronald studies the genes that make plants more resistant to disease and stress. In an eye-opening talk, she describes her decade-long quest to help create a variety of rice that can survive prolonged flooding. She shows how the genetic improvement of seeds saved the Hawaiian papaya crop in the 1950s — and makes the case that it may simply be the most effective way to enhance food security for our planet’s growing population.
