The 국제자연보전연맹 (IUCN) is a global organization dedicated to the conservation of nature and the sustainable use of natural resources. Founded in 1948, it brings together governments, non-governmental organizations, scientists, and experts to address environmental challenges. The IUCN is known for its work in assessing the conservation status of species and ecosystems through its 적색목록 (Red List). IUCN also plays a crucial role in promoting international cooperation on biodiversity and environmental issues. It organizes conferences, provides policy advice, and supports conservation projects worldwide. The organization aims to influence global environmental policies and practices to protect the planet's biodiversity for future generations.
