As Prince of Wales, Charles undertakes official duties on behalf of the Queen. Charles founded The Prince's Trust in 1976, sponsors The Prince's Charities, and is a patron, president, and a member of over 400 other charities and organisations. As an environmentalist, he raises awareness of organic farming and climate change, which has earned him awards and recognition from environmental groups. His support for alternative medicine, including homeopathy, has been criticised by many in the medical community, and his views on the role of architecture in society and the conservation of historic buildings have received considerable attention from British architects and design critics. Since 1993, Charles has worked on the creation of Poundbury, an experimental new town based on his preferences. He is also an author and co-author of a number of books.
