The member organization in a particular country may name itself Friends of the Earth or an equivalent translated phrase in the national language, e.g., Friends of the Earth (US), Friends of the Earth (EWNI) (England Wales and Northern Ireland), Amigos de la Tierra (Spain and Argentina). However, roughly half of the member groups work under their own names, sometimes reflecting an independent origin and subsequent accession to the network, such as Pro Natura (Switzerland), the Korean Federation for Environmental Movement, Environmental Rights Action (FOE Nigeria) and WALHI (FOE Indonesia).
