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

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

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.

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?

A new politics can spark the clean-energy revolution that will serve as a foundation for a new era of human prosperity, protect the world's forests, stabilize the climate, and preserve the diversity of life on the planet.

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.

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?
