GrowNYC 7th Annual New Green City

Learn how to reduce your carbon footprint with this annual environmental fair that boasts tons of interactive exhibits for kids and adults. While parents improve their DIY skills with home weatherization tutorials, the little ones can visit Kids Korner for environmental-themed games and art projects. Stay for the Iron Chef competition using locally grown produce, and don’t forget to bring old cell phones and textiles to drop off at the fest’s on-site compost and recycling bins. Free. All ages.
