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.

The Chipko activists have always been close to my parents, since my father was among the few forestry officials who supported them within the bureaucracy. And I was involved with the Chipko movement in my student days.

The occupation of America (and Columbus's arrival quite clearly was an occupation, no one can deny that) meant that the entire history of the Native Americans was rendered invisible. The land could only be occupied if it was first defined as empty. So it was defined as a wilderness, even though it had been used by native people for millennia.

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.

Nature has given us this for free, it was meant to sustain us, we will not allow it to become a monopoly to finance the Imperial Army.

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.

Biopiracy (is) biological theft; illegal collection of indigenous plants by corporations who patent them for their own use.
