There are many institutions engaged in ecological protection in the world, including organizations initiated by governments in cooperation with each other and groups initiated by non-governmental public welfare fund-raising. Some of these institutions focus on specific ethnic groups in the ecosystem, such as birds, rhinoceroses or insects, while others focus on specific ecological environments, such as wetlands or oceans. For example: CITES, WWF, World Society for the Protection of Animals (WFPA), IUCN, International Committee for the Protection of Birds (ICBP), International Center for Insect Physiology and Ecology (ICIPE), International Wetland Organization (also known as wetlands international and wetlands international), International Marine Science Organization, Task Force on the Decline of Amphibian Population, International Rhino Foundation (IRF), Bird Protection International (BCI) and Conservation International. International Crane Foundation (ICF), World Forest and Sustainable Development Council (WCFSD), Animal Foundation of Asia (AAF), Wild Aid, Species Survival Committee (SSC), etc. In the 2 1 century, with the increasing attention of human beings to the changes of ecosystem, the division of labor and integration of such institutions has become increasingly frequent.
