This week on Earth Matters, we're tuning into Dr Vandana Shiva speaking in Sydney in February 2015.

Dr Vandana Shiva is a scientist, ecologist, author and winner of the Sydney Peace Prize. She speaks about food sovereignty and seed freedom, the threats created by industrial globalised farming, industrial monocultures and the use of chemicals. She tells us about how genetic modification is first and foremost an industrial tool to collect royalties on seeds, monopolised by Monsanto and destroying farmers and biodiversity the world over.

This week's show is #975 and was produced by Gem Romuld.
