Come celebrate Earth Day at the annual St. Louis Earth Day Festival in Forest Park, April 25-26 from 11am - 5pm both days! The theme this year is Planet vs. Plastic, centering on vendors, sponsors, and educational resources that challenge plastic pollution and inspire more sustainable choices. Whether you are coming for the food, the live music, or the activities, you will leave more inspired about real progress being made to heal our people and our planet, more connected to those around you, and more knowledgeable about how you can take action in your daily life! The St. Louis Earth Day Festival is a community tradition to learn about sustainable practices, organizations, products, and services. Along with our 200 vendors, our Main Stage will host a sustainable fashion show, local music and performers, and we will honor and celebrate local leaders with our Sustainability Awards Ceremony. Showcasing Green Dining Alliance certified restaurants, one of our year-round programs, at our Earth Day Cafe — along with an All Vegan Zone! earthday365 Members will receive extra perks. Stay tuned for more exciting festival details!
