"We know more now than we did just a few years ago. New solutions are close at hand. It's time to put our best minds to work; to turn technology and the power of the marketplace to the advantage of the environment; to create; to innovate; to tip the scales in favor of recovery, restoration, and renewal. Every American expects and deserves to breathe clean air, and as President, it is my mission to guarantee it -- for this generation and for the generations to come. If we take this commitment seriously, if we believe that every American expects and deserves clean air, and then we act on that belief, then we will set an example for the rest of the world to follow."
