THE BEST! Ethical organization deeply rooted in reality works passionately for environment as a whole. Communication is amazing with frequent emails suggesting timely actions and follow-up on progress. Center for Biological Diversity has helped me be a much more informed and active environmentalist and I thought I was pretty good before! It has also made it much easier to convey the info to my friends who are not as motivated as I to follow environmental issues. It is so heartening to get the news that our actions have succeeded. They actually leave me feeling hopeful about our environment which is a very tough thing to do. And that keeps me motivated to continue working.
