If a picture is worth a thousand words, there’s a whole lot of talking going on right now at the Eleventh Annual Poster Biennial of Mexico. “Disenyadores por la tierra,” (Designers for the Earth) is an exhibition of poster design down at the COP16 Climate Change Village exploring the theme of the relationship between man and his environment. Click through all of the pictures of these eye-opening posters and visit the site to download them for yourself.
