“Plant trees. They give us two of the most crucial elements for our survival: oxygen and books.”

“Our most basic instinct is not for survival but for family. Most of us would give our own life for the survival of a family member, yet we lead our daily life too often as if we take our family for granted.”

“The trees, the flowers, the plants grow in silence. The stars, the sun, the moon move in silence. Silence gives us a new perspective.”

“Raised by two mothers...wow, most of us barely survive one”

“Evolution, energy, and ethics are the core elements that will guide us along the challenging path toward the Life Era: the first - evolution - because a good understanding of our universal roots and of our place in the cosmic scheme of things will help us create a feasible future course; the second - energy - because our fate will bear strongly on the ways that humankind learns to use energy efficiently and safely; and the third - ethics - because global citizenship and a planetary society are crucial factors in the survival of our species.”

“Planting trees, I myself thought for a long time, was a feel-good thing, a nice but feeble response to our litany of modern-day environmental problems. In the last few years, though, as I have read many dozens of articles and books and interviewed scientists here and abroad, my thinking on the issue has changed. Planting trees may be the single most important ecotechnology that we have to put the broken pieces of our planet back together.”
