“The planet's biggest problems have to do with sustainability, environmental decline, global poverty, disease, conflict and so forth. Really, they're all interconnected - it's one big problem, which is that the way we're doing things can't go on.”

“The planet's biggest problems have to do with sustainability, environmental decline, global poverty, disease, conflict and so forth. Really, they're all interconnected - it's one big problem, which is that the way we're doing things can't go on.”

“The idea that we are going to be able to take our entire society as it currently works and simply change the source of energy and make it sustainable is not actually congruent with reality.”

“Climate change is not a discrete issue; it's a symptom of larger problems. Fundamentally, our society as currently designed has no future. We're chewing up the planet so fast, in so many different ways, that we could solve the climate problem tomorrow and still find that environmental collapse is imminent.”

“Cities offer us powerful leverage on our most stubborn, wasteful practices. Long commutes in our cars, big power bills from our energy-hogging buildings, shopping trips to buy stuff that'll spend a few short months in our homes and long centuries in our landfills.”

“If mass media, social isolation in the suburbs, alienating workplaces and long car commutes create a bunker mentality, the Internet does the opposite.”

“The Internet has made some phenomenal breakthroughs that are still only poorly understood in terms of changing people's ideas of us and them. If mass media, social isolation in the suburbs, alienating workplaces and long car commutes create a bunker mentality, the Internet does the opposite.”

“I think there's a gigantic generation gap in terms of how people understand the Internet and how much they think technology is an important factor in social change.”

“I'm fascinated with design. I realized early that I had no talent in that direction, but I love talking with architects and designers about what they do. I appreciate applied creativity as a source of pleasure and meaning.”

“By fundamentally changing how we design the places and systems that enable our daily lives, we can slash emissions way beyond the immediate carbon savings - because our own personal emissions are just the tip of a vast iceberg of energy and resources consumed far from our view.”

“It's not that hard to imagine the natural world recovering it's health in our absence: it's more difficult, and more necessary, to imagine it recovering its health in our presence.”
