Hundreds of visitors came to get inspired and play with us at our Climate Art Exhibit on Sep. 14-15 at the Mill Valley Fall Arts Festival. Green Change hosted this special exhibit to engage more people to go green and fight climate change. We collaborated with these talented artists and dozens of volunteers to create this year’s featured presentation: Ann Dodge, Tess Felix, Fabrice Florin, Janey Fritsche, Al Grumet, Aurora Mahassine and Randy Rosenberg. Together, we transformed the redwood grove at Old Mill Park into a creative space for climate action. We inspired hundreds of conversations about climate change through vibrant artworks, visual storytelling, interactive installations and fun activities for all ages. Over a hundred people signed up as Green Change members, dozens pledged to take climate action and many more played our educational games and learned new information to help them go green. Our climate art exhibit featured: • Ocean Plastic Portraits – stunning portraits made from recycled materials found on beaches • Seeds of Change – a multi-dimensional living art installation rising 20 feet up in the redwood trees • Keeping Score – a fun corn hole game about our food choices • Hitting Home – an origami house activity about our energy choices • Alchemy of Fire – mixed-media paintings about the threat of wildfires • This Island Earth – paintings celebrating the beauty and spiritual power of nature • Earth Bike – a unique art float created to inspire people to go green • Green Change – an information table for learning about climate action This was a fun and rewarding experience for all participants, bringing together hundreds of people and inspiring them to make a green change in their lives. The majestic redwood grove at Old Mill offered an ideal setting for helping each other protect nature and our future. Special thanks to our gracious hosts Erma Murphy and Sylvia Barsky at MVFAF — and to all the volunteers who so generously helped us present our work for this transformative experience!
