There is so much going on in the world that makes environmental sense. The Facebook page Grow Food, Not Lawns, has a lot of  great stuff about what you can grow and how to go about it. It's time well spent and you can jump into discussions along the way. I found that most of the comments people post are helpful and positive.
Via a post on The Yardener I got to watch a tutorial about building an English Wattle Fence and was delighted when the host mentioned that the materials were clippings. What a great way to make use of tree prunings!
My quest for good news on the environmental front continues.
