In just over 4 decades, WWF(formerly known as the World Wildlife Fund) has become one of the world’s largest and most respected independent conservation organizations.

With almost 5 million supporters distributed throughout 5 continents, WWF has offices in over 90 countries and can safely claim to have played a major role in the evolution of the international conservation movement.

Since 1965, WWF has invested over US$1 billion in more than 12.000 projects. This section explains how the organization grew from being a small group of committed wildlife enthusiasts into a global network, supported by people from all walks of life, who, like WWF, care about the welfare of our planet.
