I'm currently in the process of redoing the Nature is a Human Right website ([login to view URL]), and I’m looking for 3 illustrations, to accompany/capture these 3 ideas:
1) Wellbeing: Being surrounded by nature (green, leafy plant life) makes us healthy and happy
2) Urbanisation: The world today is increasingly grey
3) Future: A world in which cities are more green than grey
These will sit on the homepage and be accompanied by more detailed explanatory text (you can find the sort of thing on the current homepage).
