Walk the Talk with Mark Lynas

Mark Lynas is a British author, journalist and environmental activist who used to sneak into people's farms and burn entire crops just because they used genetically modified technology. Suddenly, he has made a complete switch. On Walk The Talk, he talks to Shekhar Gupta, Editor-in-chief, Indian Express, and tells him why suddenly he has turned pro-genetically modified crops and why has he started criticizing anti-genetically modified activists? He also speaks about how important are genetically modified crops and nuclear power for mankind.
