The full form of WWF is "World Wide Fund for Nature". It is one of the worlds largest conservation organizations, with over five million supporters worldwide, working in more than 100 countries and supporting around 3,000 conservation and environmental projects. The organization was established on April 29, 1961, and it opened its first office in the Swiss town of Morges and is registered under Swiss law. WWF focuses on two broad areas to achieve its mission: biodiversity and footprint. Biodiversity refers to the variety of life on Earth, and the organization focuses on critical species and places that need to be conserved to protect the rich biodiversity of the Earth. Footprint refers to human activity that is harming natural resources, and the organization is working to ensure the optimum utilization of natural resources like land, water, and air.
