Greenpeace is the leading independent campaigning organization that uses non-violent direct action and creative communication to expose global environmental problems and to promote solutions that are essential to a green and peaceful future. For 30 years, Greenpeace has tackled the most critical environmental issues. Today work focuses on six major efforts: saving ancient forests, stopping global warming, exposing toxic waste, protecting the oceans, eliminating the threat of genetic engineering, and ending the nuclear age. Greenpeace does not accept donations from governments or corporations. Its 250,000 members in the United States and 2.5 million members worldwide form the backbone of the organization.
