A great way to stay passionate about the environment is to get out in it. For me, that usually means hiking, but for many others it can mean rock climbing, mountain biking, or even gardening. In my latest job I've been leading interpretive hikes throughout the Aspen area, and I often ask the people on my tours why they like getting outside. In general responses usually involve a sense of being reinvigorated and relaxed after taking a walk or seeing a beautiful view.
In the words of John Muir:
"Everyone needs beauty as well as bread. Places to play in and pray in, where nature may heal and provide strength to body and soul."
