Pratchett was a trustee for Orangutan Foundation but was pessimistic about the future of orangutans. His activities included visiting Borneo with a Channel 4 film crew to make an episode of "Jungle Quest" in 1995, seeing orangutans in their natural habitat. Following Pratchett's lead, fan events such as the Discworld Conventions have adopted Orangutan Foundation as their nominated charity, which has been acknowledged by the foundation. One of Pratchett's most popular fictional characters, the Librarian, is a wizard who was transformed into an orangutan in a magical accident and decides to remain in that condition as it is so convenient for his work.
