They work on various issues, including climate change, wildlife conservation, and pollution reduction. These organizations often engage in research, advocacy, and education to raise awareness about environmental challenges and solutions. Many environmental organizations operate at local, national, or global levels. Examples include the World Wildlife Fund, Greenpeace, and Sierra Club. They collaborate with governments, businesses, and communities to implement policies and initiatives that support environmental health and sustainability.
