Bill Moyers recently gave a speech to the Society of Environmental Journalists Convention. It's a rousing and bracing call to action. You can read it at CommonDreams. Here's a taste:

The Gilded Age has returned with a vengeance. Washington again is a spectacle of corruption. The promise of America has been subverted to crony capitalism, sleazy lobbyists, and an arrogance of power matched only by an arrogance of the present that acts as if there is no tomorrow. But there is a tomorrow. I see the future every time I work at my desk. There, beside my computer, are photographs of Henry, Thomas, Nancy, Jassie, and SaraJane - my grandchildren, ages 13 down. They have no vote and they have no voice. They have no party. They have no lobbyists in Washington. They have only you and me - our pens and our keyboards and our microphones - to seek and to speak and to publish what we can of how power works, how the world wags and who wags it. The powers-that-be would have us merely cover the news; our challenge is to uncover the news that they would keep hidden.
