The interactive Green City Calendar is a weekly-updated resource to help people find environmental volunteer options and greening projects in the San Francisco Bay Area. Through the variety of hands-on ecosystem restorative work, bike rides, hikes, classes, workshops, and celebrations listed in this calendar, we can build a symbiotic balance between humanity and the planet, and promote sustainable urban living. Email listings of ecological/sustainable volunteer opportunities or events (San Francisco Bay Area only) to: mail@planetdrum.org
