The Surfrider Foundation is a network of activists across the U.S. who are dedicated to protecting coastal environments, as well as our shared oceans. They function on local, regional, and national levels, allowing chapters in different communities to hold their own events while also providing support for large scale legislation related to water protection.
A local chapter in Cape Fear, North Carolina, have a tradition that's now in its fourth year, in which they gather after the holiday season to bury their Christmas trees on the beach. It sounds like a strange mix up of natural materials, but Climate Connections reports that the trees are helping to rebuild sand dunes in the area. After being staked down, the wind blows sand across the old trees and they gradually become new dunes, protecting the shore from erosion.
