Greenpeace volunteers promote the Greenpeace Book Campaign to the tens of thousands of authors, publishers and members of the general public at the Hay-on-Wye Book Festival. A total of 55 authors sign Greenpeace's special pledge book - a giant Victorian scrapbook - to show their support for the campaign. The campaign urges the UK publishing industry to shift over to use ancient forest friendly paper - that's paper that maximises recycled content with any virgin fibre coming from Forest Stewardship Council certified sources, which guarantees forests are managed in an environmentally and socially responsible way.
