Scientist and philosopher Vandana Shiva is a virtual rock star in the global battle over genetically modified seeds. These seeds -- considered "intellectual property" by the big companies who own the patents -- are globally marketed to monopolize food production and profits. Opponents challenge the safety of genetically modified seeds, claiming they also harm the environment, are more costly, and leave local farmers deep in debt as well as dependent on suppliers.
In an excerpt of a conversation that will air on Moyers & Company this weekend, Shiva -- who founded a movement in India to promote native seeds -- explains how "everything begins with seed," and addresses the perils of patenting them. She also encourages each of us to ask: "Where am I complicit in the war against the Earth?"
