The World Wildlife Fund (WWF) was founded in 1961 in Switzerland by prominent environmentalists who realized more funding was needed to protect the environment. WWF's goals are to preserve biodiversity and species, restore endangered populations, and achieve a balance between human and natural resource use. Notable successes include increasing giant panda and sea turtle populations through protected areas. Actor Leonardo DiCaprio partners with WWF to support campaigns like Save the Tigers Now, which doubled Nepal's wild tiger population. WWF's iconic panda logo was inspired by one in the London Zoo in 1961.
