The World Wide Fund for Nature is an international NGO that works in the field of wilderness preservation and the reduction of human impact on the environment. WWF is the world's largest conservation organisation with presence in over 100 countries and support of nearly 3,000 conservation and environmental projects. Having invested over $1 billion in more than 12,000 conservation initiatives since 1995, WWF works on ambitious programmes to establish green corridors for wildlife, restore major river flows, protect forests and oceans and press for global commitments to end illegal trade in wildlife. Specifically, its current work is focussed on the following six areas: food, climate, freshwater, wildlife, forests, and oceans. Examples of WWF projects dedicated to sustainable food systems cover aspects of production, consumption as waste, such as Showcase, SaveOneThird and Eat4Change. WWF is also closely involved in global fora such as the UN Food Systems Summit.
