St. Louisan David Henry was fed up, back in 2013, with public indifference to climate change, and denial of the science defining climate issues. He wanted to shake his fellow humans by the scruff of the neck or, as he says, "at least figure out how they became such idiots."

David is a gentle, calm, thoughtful guy; really not a scruff-shaker. But he does care passionately about dealing with this key problem of our time. So he embarked on a one-man climate action: walking - over 1,000 miles - and having conversations with people he met, about climate change. A vivid feature of this trip was the cart he rigged to carry his stuff. It looked, inadvertently, like a giant white mailbox, with his Climate-Walker.org identity emblazoned on the side. This climate messenger had no trouble starting conversations!

David Henry reported on his trip, fresh off the road, in a 2013 Earthworms conversation. Today, he shares the perspective he's gained in writing this tale, along with stories from his new book, David and the Giant Mailbox - Walking 1,000 Miles to Talk About Climate Change (2015, Good Boots Press)

David's climate of frustration has turned into a hopeful perspective, a resource we can sure use. And his determination to get us climate-dependent humans to ACT has not changed.
