Greenpeace is a non-governmental environmental organization founded in 1971 with offices in over 40 countries. It aims to ensure the Earth's ability to sustain life and focuses on issues like global warming, deforestation, overfishing, and anti-nuclear issues. Greenpeace uses direct action, lobbying, and research and does not accept government, corporate, or political funding, relying instead on over 2.8 million individual supporters and foundation grants.
