15. Power Up at GrowNYC Columbia University Green Market

If you happen to be in Morningside Heights on a sunny Thursday or Saturday, you can stop by the local farmer’s market for a chance to snack on some fresh apples, baked goods, lemonade, and more. The market also offers several opportunities to do some good for the planet: GrowNYC hosts a clothing collection from 8:00 AM to 3:00 PM, and a food scraps compost open from 8:00 AM to 1:00 PM. Vendors sell anything from food to clothes to jewelry to electronics.
