Let no man say it cannot be done

We need an economy for the twenty-first century, one that is in sync with the earth and its natural support systems, not one that is destroying them. The fossil fuel-based, automobile-centered, throwaway economy that evolved in western industrial societies is no longer a viable model — not for the countries that shaped it or for those that are emulating them. In short, we need to build a new economy, one powered with carbon-free sources of energy — wind, solar, and geothermal — one that has a diversified transport system and that reuses and recycles everything. We can change course and move onto a path of sustainable progress, but it will take a massive mobilization — at wartime speed. … learn more→
