One of the movements we have developed is to say that, just as intellectual property rights protect the inventions of individuals, common rights are needed to protect the common intellectual heritage of indigenous peoples. These are rights that are recognized through the Convention on Biological Diversity. We are working to make sure that they become foundations of our jurisprudence.

If India is an emerging economy with millions of new consumers, sell them the Volvo. Sell them the Cielo car. Sell them whatever you can, hamburgers and KFCs. It’s the middle classes who have moved into being able to own a car, a refrigerator. For them there is this mantra that the General Electric refrigerator is better than some other model, that the Cielo car is fancier than the Ambassador.

Food is the place where you begin.

We have to build movements in the face of trade retaliation on the basis of people's democratic rights, on the basis of an ancient heritage of collective innovation. We work from the grassroots all the way to the national government and the World Trade Organization. It basically means being very multidimensional in our campaigns. And that is where part of the fun is. It involves both resistance and creativity. It involves constructive action, while at the same time saying "no."

I have a deep connection with Mahatma Gandhi, partly because my mother was a very, very staunch Gandhian and brought us up that way. When I was six years old, and all the girls were getting nylon dresses, I was very keen to get a nylon frock for my birthday. My mother said, “I can get it for you, but would you rather—through how you live and what you wear and what you eat—ensure that food goes into the hands of the weaver or ensure that profits go into the bank of an industrialist?” That became such a checkstone for everything in life.

My father had been a forester and I had grown up on those hills. I had seen forests and streams disappear. I jumped into Chipko movement and started to work with the peasant women. I learned from them about what forests mean for a rural woman in India in terms of firewood and fodder and medicinal plants and rich knowledge.

My travels through physics really are the same urges that make me travel through ecology. They are not really different, except that there is an added dimension of seeing ecological destruction and seeing the very life-support system that makes us survive on this planet being destroyed. That makes me do more than just inquire; it compels me to act and to intervene.
