Protected lands are areas designated to conserve natural resources, wildlife, and ecosystems. These lands can include national parks, wildlife refuges, and nature reserves, where human activities are limited to preserve the environment. The goal is to maintain biodiversity and protect habitats from development and pollution. Governments and organizations often manage protected lands to ensure they remain intact for future generations. Examples of protected lands include the Yellowstone National Park in the United States and the Great Barrier Reef Marine Park in Australia. These areas provide essential benefits, such as clean air, water, and recreational opportunities for people.
