The most critical natural resource on the planet is at risk, but its not one we’re accustomed to thinking of as endangered.

Dr. Vandana Shiva is the founder of Navdanya International , an India-based science and policy research center. Its mission: "To protect nature and people's rights to knowledge, biodiversity, water and food."

Dr. Shiva notes that pesticide use contributes to the "desertification" of soils, a process that is accelerated when the soil is poor to begin with.

One little-known consequence of the widespread adoption of genetically modified cotton seed by farmers in India has been a surge in suicides by debt-ridden farmers whose crops do not earn enough to pay their seed bills. Dr. Shiva says that a generation ago, suicide was rare in India, but the numbers now suggest there is a new death approximately every 20 mintes.

On August 27^th, the Jackson Theater at Sonoma Country Day School in Santa Rosa will host an evening with Dr. Shiva, advocate and author as well as winner of the alternative Nobel Peace Prize.
