Today international conservation organizations serve as environmental consultants for governments and large corporations interested in reducing pollution, setting aside protected areas, and conserving biodiversity. Organizations like the International Conservation Union (IUCN), The Forest Trust, the Rainforest Alliance, Conservation International (CI), the Wildlife Conservation Society (WCS), the Sierra Club, The Nature Conservancy (TNC), and the World Wildlife Fund for Nature (WWF) act as mediators between various development interests, policy makers, local peoples, scientists, and activist groups in promoting conservation. These organizations initiate and support a broad range of conservation-related activities, from arranging international conferences to establishing community-based conservation projects to maintaining parks and reserves. Keeping attuned to economic realities, they work to integrate the latest scientific findings into preservation efforts.
