The World Wide Fund for Nature (WWF) is an international non

environment. The organization was formed as a charitable trust on September

an initiative of Julian Huxley and Max Nicholson.
It is the world's largest independent conservation organization with over 5
million supporters worldwide, working in more than 90 countries, supporting
100 conservation and environmental projects around the world. It is a charity,
