It will be politics that determines the material welfare of future generations: the pace at which we advance toward our destination of economic bliss, andnperhaps, whether we continue to advance at all.

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 highest and best use of our time that really matters over the next decade will be working to elect clean-energy candidates, especially in swing states and swing districts around the country.

One hundred years ago, visionary political leaders from the Progressive Era established a system of national forests and parks in our country that are the envy of the world and today are the treasure of an entire nation. Why not a similar, global vision for our generation?

The Arctic is the planet's air conditioner and it's starting to break down.

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

Stabilizing the climate is not about saving the human species... Stabilizing the climate is a precious opportunity to pass on to all future human beings gifts of immense value, gifts that, once gone, will be beyond the imagination and skill of humanity to recreate.

Electing clean-energy leaders into the Senate, the House, and the Oval Office - and getting it done in the next few years - is the only real solution to climate stabilization at acceptable levels.

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.

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?

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?’
