Biotech and geo engineering have the same mindset, of engineering, of power, of control, of mastery of nature.

I did physics because of my love of nature. As a young student of science, I was taught that physics was the way to learn nature. So my travels through physics really are the same urges that make me travel through ecology.

It's worse than slave trade because what is being traded is the very knowledge that makes survival possible for 80 percent of the people of this world. These 80 percent live on the biodiversity and the knowledge they have evolved as part of a rich collective heritage involving the use of seeds for growing crops and medicinal plants for healing.

Whenever we engage in consumption or production patterns which take more than we need, we are engaging in violence.

My links with [Mahatma] Gandhi now are very political links because I do not believe there is any other politics available to us in the late twentieth century, a period of a totalitarianism linked with the market. There is really no other way you can do politics and create freedom for people without the kinds of instruments he revived. Civil disobedience is a way to create permanent democracy, perennial democracy, a direct democracy.

My personal background is actually very unusual for the kind of career I chose. I didn’t meet anyone who had ever done physics in my life. I grew up in the Himalayan forests. My father was a forest conservator, which meant that if I wasn’t in school I was in the forests with him. That has been very largely responsible for my ecological inclinations.

We are either going to have a future where women lead the way to make peace with the Earth or we are not going to have a human future at all.
