If we are ever to halt climate change and conserve land, water and other resources, not to mention reduce animal suffering, we must celebrate Earth Day every day - at every meal.

Every day is Earth Day, and I vote we start investing in a secure climate future right now.

In reality, climate change is actually the biggest thing that's going on every single day.

Knowledge empowers people with our most powerful tool: the ability to think and decide. There is no power for change greater than a child discovering what he or she cares about. (Speech about Global Warming read on the National Mall for the 40th anniversary of Earth Day, 2010)

I'm a Gemini, so I change my mind every day.

Every day I'm thinking about change.
