Schools urged to back 'message in a book' initiative.
Oxfam wants schoolchildren to write a personal letter on world issues, which will then be placed in the back of second-hand books and sold at the charity's stores.
The Message in a Book community initiative aims to highlight the Rio 20+ Earth Summit next month.
Oxfam will provide resources for teachers to encourage primary and secondary school pupils to think about global inequality, sharing the Earth's resources and combating poverty.
Students will then write a personal letter in response to the global issues, which will be inserted into donated books to inspire the charity's customers.
As part of the project, schoolchildren are also being invited to collect unwanted books from home to donate.
Val Griffiths, Oxfam area trading manager for Wales, said: "Oxfam stores play a central role in local communities and this initiative is an excellent way of linking schoolchildren and our customers to continue spreading Oxfam's message.
"Message in a Book is a unique scheme that gives school pupils an opportunity to share their views on issues that they may not usually discuss or comment on. It continues to raise the profile of Oxfam's work worldwide while encouraging the support and interest from our communities and building awareness in local schools, which is very important." * For more information about Message in a Book go to www.oxfam.org.uk/messageinabook
