Prince Charles is right. We need a “revolution.”

Last week, I traveled to Louisville to join Prince Charles in his call for a “sustainability revolution” to renew the natural systems that support us all, as part of an event hosted by the Institute for Healthy Air, Water and Soil.

You know we’ve traveled a great distance in this world when the future king of England comes to America to call for revolution. And you know how far we have to go when a revolution is what we need.

It was an honor to meet the Prince of Wales and the Duchess of Cornwall, and an even greater privilege to walk with royalty on the great journey to a brighter future for our children.
