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.

I do sculpting sometimes when I have the time, and the first thing I sculpted was a bust of [Albert] Einstein. It still sits on my table and still inspires me. He was a person who triggered my imagination and my ideas.

You are not Atlas carrying the world on your shoulder. It is good to remember that the planet is carrying you.

Because of these new car models there is suddenly on the streets of Delhi a new intolerance by the motorists for both the cows and the cyclists. So for the first time the sacred cow in India, which used to be such a wonderful speed-breaker, is now seen as a nuisance. For the first time, I’ve seen cows being hit and hurt. These guys just go right past, and if the cow is sitting on the road, they don’t care. We can’t afford to have a sacred car rather than a sacred cow.

The primary threat to nature and people today comes from centralising and monopolising power and control. Not until diversity is made the logic of production will there be a chance for sustainability, justice and peace. Cultivating and conserving diversity is no luxury in our times: it is a survival imperative.

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.

When the forest is destroyed, when the river is dammed, when the biodiversity is stolen, when fields are waterlogged or turned saline because of economic activities, it is a question of survival for these people. So our environmental movements have been justice movements.
