The World Wildlife Fund is a nature conservation organization that began in 1961. Their mission is “to build a future in which people live in harmony with nature”. Their website provides a host of information ranging from habitats to endangered species and the threats that occur.
Under the about us section, there are 40 of their employed experts listed. Each individual has a link that provides information about them including their education and experience.
