Looking at hundreds of photos of children's feet might not be your idea of a good read. But environmental group Footprint Friends are collating a book of photos of children's painted feet, entitled Book of Dreams.
The book forms part of their campaign to engage young people in the climate change debate ahead of the United Nations' Climate Change summit in Copenhagen this December.
Their Million Feet to Copenhagen campaign is aiming for one million photos of painted feet to be uploaded to their networking website, a selection of which will be used in the book and presented to politicians at the conference.
Schools have an added incentive to get involved, as this week happens to be National Foot Painting Week.
Climate Change Secretary Ed Miliband called the campaign "unusual", but said that he welcomes "all efforts to raise awareness of the need for an ambitious global agreement at Copenhagen".
