Evolution is not something to be feared. It's to be celebrated, embraced, and understood.

Life in the ocean makes Earth hospitable. We are sailing along in the universe and we have a blue engine that is making everything alright.

The sudden release of five million barrels of oil, enormous quantities of methane and two million gallons of toxic dispersants into an already greatly stressed Gulf of Mexico will permanently alter the nature of the area.

It doesn't matter where on Earth you live, everyone is utterly dependent on the existence of that lovely, living saltwater soup. There's plenty of water in the universe without life, but nowhere is there life without water.

What we put into the atmosphere in terms of burning fuel is unprecedented.

Everybody can make choices that will make peace with the natural world.

We must protect our ocean as if our lives depend upon it, because they do.
