Adapted from GF's website: GreenFest Philly is a one-day street fair FREE to the public. Over 200 exhibitors and about 20,000 people attended the area's largest environmental event. The event featured vegetarian food, sneaker recycling, live music & entertainment, kids activities, bicycle valet, yoga, local produce, organic pastry contest, composting and recycling, Eco Exchange Fashion Show & Clothing Swap, Water Quality Symposium and Eco-Film Forum. This year's theme was water quality so visitors could grab their reusable water containers and fill up at the no-waste drinking water stations.
