Pamela Ronald: The case for engineering our food

Pamela Ronald studies the genes that make plants more resistant to disease and stress. In an eyeopening talk, she describes her decadelong 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 planets growing population.
