WWF - climate change poster ideas...

Global warming will kill off many animal species if we don't reduce the levels of CO2 in the earths atmosphere. Here are my initial poster ideas, I've enjoyed working with the logo so far and incorporating more playful type, with the aim to catching the audiences eye, the posters are aimed at a wide audience of a range of ages so I thought too sterile typography would not suit this, so I am working on more illustrative typography, still trying and testing at the moment till I find something successful.
