GOSHEN – Vandana Shiva was on the fast track for a career as a nuclear physicist in the 1970s, working in an atomic research center in Bombay in her native India.

But when her sister, a medical doctor, pointed out Shiva’s lack of understanding of nuclear hazards, she planted a seed in Shiva’s mind. That seed took root and eventually caused Shiva to abandon her nuclear ambitions and dedicate her life to what she calls “sciences that defend life.”

In particular, she focuses on food security and sustainable farming to protect and promote the most elemental form of life: the seed.

In a speech titled after her latest book, “Soil Not Oil” (South End Press, 2008), Shiva, whom Time magazine calls an environmental hero, told a full house at the Goshen College Church-Chapel during a recent talk that the world should be focused on food security instead of devoting limitless resources to oil and unsustainable energy production that threaten to devastate the planet and its people if left unchecked. She explained parallels she sees between her past career and her present work.

“Feeding ourselves has become like warfare,” she said, citing 1 billion people worldwide going hungry, recent riots in more than 30 countries because of increasing food prices and violent conflicts erupting when industrial farming companies displace traditional farmers in emerging countries like India. Additionally, Shiva mentioned literal wars fought today over oil and water, such as the conflict in Darfur that began with the effects of a drought.

Even the elements of war and food have become the same, she pointed out, with leftover chemicals from weapons – nitrogen, Agent Orange and DDT – being used to fertilize and treat crops. “Agriculture begins to look more and more like war against the earth,” she said.

This “war” is destroying soil, wasting water and other resources, polluting the planet and devaluing and destroying human life and work. And for no more food.

“We’ve been sold a major myth on the grounds that the application of chemicals will improve yield. It’s not true,” she said. “It will kill soil.”

Shiva pointed out industrial farming uses 10 times as much water as ecological farming. And industrial agriculture is inherently wasteful because it takes 10 kilocalories of energy to produce 1 kilocalorie of food, she explained. Industrial farming of animals is even less efficient and requires 100 kilocalories of energy to produce 1 kilocalorie of protein.

“If you’re living on a planet of shrinking resources, it doesn’t make sense,” she said. Especially when this wasteful, polluted farming has replaced the perfect cycle of traditional farming that created no emissions, waste or conflict, she said.
