Hundreds, if not thousands, of organizations exist to help protect wildlife. Some organizations work on an international scale, some work within a national scope and some organizations focus on a state or local level.
On an international level, some of the most influential organizations are the World Wildlife Fund, Greenpeace, the National Geographic Society, Wildlife Conservation Society and Defenders of Wildlife. These organizations fight for environmental justice on every level, and many work to reduce pollution or to preserve wild areas in addition to fighting species extinction.
Wildlife protection groups at every level can boast of real and significant accomplishments. For example, the Defenders of Wildlife helped to convince the United Nations to ban high-seas, large-scale driftnet fishing to help save dolphins and other ocean species. Greenpeace is one of the most well known organizations, and it acts aggressively in the name of defending the environment and wildlife.
Within the United States, one of the best-known organizations is the Sierra Club. As the oldest and largest environmental group in America, with over 1.3 million members, the Sierra Club is constantly campaigning to save the environment and the country's wildlife. Most of these groups help to affect real change for wildlife and the environment with their campaigns. They also help to monitor and maintain what they have accomplished.
