It is from the Himalayan forests and ecosystems that I learned most of what I know about ecology.

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

Whenever we engage in consumption or production patterns which take more than we need, we are engaging in violence.

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.

Seen from a monocultural perspective, manipulating objects is very, very clever. But seen from a multidimensional perspective, from a perspective of diversity, this is extremely crude because what we have lost out on is a cow that serves as a source of sustainable energy.

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.

Soil, not oil, holds the future for humanity.
