conservation of natural resources
The commitment of nations to conservation policies varies. Some nations, such as Iraq, Cambodia, and the republics of the former Soviet Union, have no protected areas, while 38% of Ecuador's land is protected and 44% of Luxembourg's is. (In the United States 7% of the land is protected.) Plants and animals have been protected through curtailment of whaling and the taking of porpoises in tuna seines and restrictions on logging. Endangered species have been protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES, 1979). In addition to CITES, United Nations Conference on Environment and Development (the "Earth Summit," 1992) produced an agreement to protect the world's biological diversity. The World Wildlife Fund, Greenpeace, and other organizations also have been active in promoting conservation internationally.
