Nature has gifted this rich biological diversity to us. We will not allow it to become the monopoly of a handful of corporations. We will keep it as the basis of our wealth and our sustenance.

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.

Given that I was interested in physics, I think it was easier for me to do physics in India.

I absolutely get thrills from taking on these big guys and recognizing how, behind all their power, they are so empty. I just keep going at it. Each of these balloons does deflate. I’ve seen a lot of balloons get deflated in my life.

I still can't figure out what inspired me to do physics. But since I was nine or ten years old, I wanted to be like [Albert] Einstein. He was my hero. I knew no physicists. I knew no scientists. I had nobody around me. And I went to a convent that didn't even have higher mathematics and physics. I taught myself these subjects in order to get into university.

I started out in nuclear physics. But after I became more sensitized to the environmental and health implications of the nuclear system - I was being trained to be the first women in the fast-breeder reactor in India (and was in it when it first went critical) - I didn't feel comfortable with it. So I went into theoretical physics.

The role of geo-engineering should, in a world of responsibility, in a world of scientifically enlightened decision making and ecological understanding, it should be zero. There is no role for geo-engeneering. Because what is geoengineering but extending the engineering paradigm?
