Now, the choice we face is not between saving our environment and saving our economy. The choice we face is between prosperity and decline. We can remain the world's leading importer of oil, or we can become the world's leading exporter of clean energy. We can allow climate change to wreak unnatural havoc across the landscape, or we can create jobs working to prevent its worst effects. We can hand over the jobs of the 21st century to our competitors, or we can confront what countries in Europe and Asia have already recognized as both a challenge and an opportunity: The nation that leads the world in creating new energy sources will be the nation that leads the 21st-century global economy.
