TreeHugger is a fast-growing web magazine, dedicated to everything that has a modern aesthetic yet is environmentally responsible. Their goal is to make sustainability mainstream. If you want doom & gloom, don't go here. They are looking for solutions, constructive developments and positive initiatives, just like we are.
They read Sierra magazine, the magazine of the Sierra Club, and they like it. If you are a member of the Sierra Club, you already get the magazine as part of your membership. If you don't get Sierra, all you need to do is join the Sierra Club. It's easy to join online.
