A day will come when our children and grandchildren will look back and they'll ask one of two questions. Either they will ask: "what in God's name were they doing?" or they may look back and say: "how did they find the uncommon moral courage to rise above politics and redeem the promise of American democracy?"

Every day we put another 110 million tons of global warming pollution into the sky as if it's an open sewer, and it's still building up. And the scientists tell us it's a race against time.

I wrote newspaper articles professionally for seven years, and I love newspapers. I'm hopeful that new business models will emerge that allow the newspaper culture to genuinely thrive in the digital age.
