The WSPA's present structure was created in 1981 through the merger of the World Federation for the Protection of Animals (WFPA), and the International Society for the Protection of Animals (ISPA). WFPA and ISPA were the first organisations to campaign internationally on animal welfare issues, highlighting problems such as the plight of Canada's seal, the devastation of the world's whale population, and the international transportation of horses. Building on this experience, WSPA staff have brought emergency aid to animals during floods, earthquakes, explosions, famines, oil spills and wars in six continents and has built up a reputation as a world leader in this field. WSPA has also undertaken high profile campaigns to focus public opinion on some of the world's most urgent animal welfare problems. Today, WSPA has offices in 13 countries worldwide and over 400,000 individual supporters.
