In the count down to Earth Hour, Do The Green Thing (quite possibly the most brilliant environment charity of all-time) is releasing a new poster everyday. Falling in line with Do The Green Thing’s mission of creativity vs. climate change, they’ve rallied together world class creatives and asked them to contribute a poster to the campaign. So here’s a small sampling. Do check out: Do The Green Thing Tumblr to see the full lineup and to buy a limited edition print.
