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."

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.

I'm a woman, born the daughter of a feminist and the granddaughter of a feminist grandfather. I don't think I could have avoided working on women's issues. I don't do it as a career or profession; it's my very essence as a human being.

We're living in the anthropocene age and now human beings will be the shapers of our future, that totally control the overall functions of not just our planet, but our relationship with other planets.

For us, not cooperating in the monopoly regimes of intellectual property rights and patents and biodiversity - saying "no" to patents on life, and developing intellectual ideas of resistance - is very much a continuation of Gandhian satyagraha. It is, for me, keeping life free in its diversity.

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."

We could replace people with fossil fuels, have higher and higher levels of industrialization, of agriculture, of production, without thinking of the green-house gases we were admitting, and climate change is really the pollution of the engineering paradigm, when fossil fuels drove industrialism. To now offer that same mindset as a solution is to not take seriously what Einstein said: that you can't solve the problems by using the same mindset that caused them.
