When you take the entire system into account, ways of developing more of something in one dimension can actually create scarcities in another. If we say we have to increase production because people need more food, more housing, more meat, or more milk, we can make one thing grow in a certain way. But by doing that we create externalities so that there are scarcities in other related things.

Uniformity is not nature's way; diversity is nature's way.

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.

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.

In nature's economy the currency is not money, it is life.

You cannot insert a gene you took from a bacteria into a seed and call it LIFE. You have not created life, instead you have only polluted it.

The first issue that compelled me was a very strange split between India being highly development scientifically (we were the third biggest scientific manpower in the world then) and yet at the same time struggling with amazing poverty. The linear equation that says that modern science equals progress and the reduction of poverty did not apply to India. It wasn't working.
