Do The Green Thing and The World Wildlife Fund are encouraging people to turn their lights off for Earth Hour on March 29th with a series of clever posters. The campaign is to inspire people to think and act differently in order to save the environment and live more sustainably.

Naresh Ramchandani, co-founder of Do The Green Thing and partner at Pentagram, stated in a press release: “Do The Green Thing has always looked to be a public service for the planet, working with world class creative talent to make brilliant inspiration, and feeding that inspiration to as many people as possible across the world to encourage them to be more sustainable in their everyday lives. … the 29 Posters are beautiful, playful, romantic, mischievous and provocative, and I hope they will inspire as many people as possible to be part of Earth Hour 2014.”

New posters are added daily until the 29th. You can see them all at dothegreenthing.tumblr.com
