The World Wide Fund for Nature (WWF) is an international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment. It was formerly named the World Wildlife Fund, which remains its official name in Canada and the United States.
WWF's giant panda logo originated from a panda named Chi Chi that had been transferred from Beijing Zoo to London Zoo in 1958, three years before WWF was established.
WWF aims to "stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature." The Living Planet Report has been published every two years by WWF since 1998; it is based on a Living Planet Index and ecological footprint calculation. In addition, WWF has launched several notable worldwide campaigns, including Earth Hour and Debt-for-nature swap, and its current work is organized around these six areas: food, climate, freshwater, wildlife, forests, and oceans.
WWF is part of the Steering Group of the Foundations Platform F20, an international network of foundations and philanthropic organizations.
