World Wildlife Fund (WWF) Campaign

• conserving the world's biological diversity
• ensuring that the use of renewable natural resources is sustainable
• promoting the reduction of pollution and wasteful consumption.”
WWF scientists and many others identified 238 ecoregions that represent the world's most biologically outstanding terrestrial, freshwater and marine habitats, based on a worldwide biodiversity analysis which the organization says was the first of its kind. In the early 2000s, its work was focused on a subset of these ecoregions, in the areas of forest, freshwater and marine habitat conservation, endangered species conservation, climate change, and the elimination of the most toxic chemicals.
