Hardtalk speaks to the original tree hugger. The phrase was coined back in the 1970s when she - along with a group of women in India - hugged trees to stop them from being chopped down. In the decades since, Vandana Shiva has become known throughout the world for her environmental campaigns. She says a billion people go hungry in the world because of the way greedy international companies go about their business. So is it a naïve world view or could we really end poverty and improve everyone's life by returning to old fashioned ways of farming?
