It's a phenomenon that started in the United States in which corporations make claims on the life forms, biodiversity and innovations of other cultures by applying for patents on them.

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.

My mother was a tremendous woman. I was just cleaning up old trunks and I found a book with her notes written during the war years, in the 1940s. She was studying in Lahore, which became Pakistan. She was writing about how women alone could bring peace to the world, that the men with all their greed and egos were creating all these tensions and violence. I always knew she was a feminist, ahead of her time.

In India, crossbreeding programs aimed at mimicking the milk yields of Western cows like the Jerseys and the Holsteins actually breed out the capacity of our animals to pull ploughs and pulley-cars. So, thanks to cross-breeding programs, we now have humpless cattle with no stamina.

I didn't leave physics because of boredom. I left it because other issues compelled me in a bigger way. And I always say to myself, "When I'm 60, I'd like to go back to what I interrupted."

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.

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.
