No generation before us has faced a decade of choices that will so profoundly impact the course of life on this planet as those we now face. And no generation before us has had the opportunity to enrich the future so vastly.

We stand at a moment in history without precedent. Decisions that are ours to make over the next ten years will have a sweeping impact on the future direction of life on the planet.

It is time to start going door to door and convincing our neighbours to vote for a clean-energy future.

The most rational defender of nature is driven by a passion for wildness that cannot be explained by an appeal to logic.

I tell my graduate students [at Bard College], ‘There are two ways to change the world: through policy, or through sustainable business.’ With sustainable business, individuals build solutions within the current system… Sustainable business asks, ‘How would nature do this?’

In the year 2007, seals, otters, lions, turtles, frogs, apes, snakes, butterflies, polar bears, cheetahs, whales are disappearing along with their variously furnished homes: cloud forests, rain forests, ice pack, boreal forests, coral reefs, forests of deciduous trees, conifer and palm.

The human response it calls for is truly heroic, requiring nothing short of rewiring the entire planet with a new generation of clean-energy technologies - and doing that very soon... Are we, as a species, capable of that kind of deliberate global response?
