I do not allow myself to be overcome by hopelessness, no matter how tough the situation. I believe that if you just do your little bit without thinking of the bigness of what you stand against, if you turn to the enlargement of your own capacities, just that itself creates new potential.

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.

The population explosion is an ecological phenomenon of displacement. Unless we solve that ecological problem of displacing people - to build huge dams, to build motorways, to take away what people need in order to survive - we will keep pumping more and more money into population programs. We will have more and more coercive and violent methods through which women's bodies are treated as experimental grounds for new contraceptives. Yet we will not have a solution to the problem of numbers.

The only way to build hope is throuhgh the Earth.

If you see cattle as a source of organic manure, animal energy, as well as milk products, then Indian cattle are not inferior. It is only when you measure them as milk machines that they become inferior. What if we measured the dairy cows of America or Jersey or the Swiss Alps in terms of their work functions? They would be terribly inferior.

The abuse of the Earth is the ecological crisis.

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.
