This organization, formerly the World Wildlife Fund, is devoted to environmental issues. Its goals are to maintain biodiversity, to promote sustainable use of renewable resources, to promote conservation and reduce waste. The organization's political agenda is to push governments to pursue these goals as well.
The impact of this group on science is very much like that of all other advocacy groups. It can affect what projects scientists take on by publicizing certain areas of research. As they promote them, the projects become better-known and are more likely to attract scientists and funding.
Given the nature of its goals, this group can also draw negative attention to science. Its goals often come into conflict with economic needs and lead opponents to distrust science and scientists.
