It’s not easy
Exit art in New York City has a cool summer series to check out. They are asking for a response to what green means to you. E-mail your submission and it will be printed out on 8 1/2 x 11 inch paper (hopefully 100% recycled!!) and displayed in their gallery. Check out this website for details!
