The correct answer is C. IUCN.
The International Union for Conservation of Nature (IUCN) is an international organization that helps the world find practical, innovative solutions to our most pressing environmental and development challenges. IUCN’s work is guided by its six strategic priorities:
- To conserve the world’s biological diversity
- To ensure that the use of natural resources is sustainable
- To promote the reduction of poverty as a means of conserving biodiversity
- To promote the integration of conservation and development
- To strengthen the capacity for conservation
- To provide knowledge and information to support conservation and sustainable use
The IUCN Red List of Threatened Species is a comprehensive inventory of the global conservation status of biological species. The Red List is used to guide conservation efforts around the world and to inform policy decisions.
The Red List is divided into nine categories:
- Extinct
- Extinct in the Wild
- Critically Endangered
- Endangered
- Vulnerable
- Near Threatened
- Least Concern
- Data Deficient
- Not Evaluated
The Red List is updated regularly as new information becomes available. The most recent update was in 2021, and it includes over 135,000 species.
The IUCN Red List is an important tool for conservation. It helps to raise awareness of the threats facing biodiversity and to mobilize action to protect it. The Red List also provides a valuable resource for policymakers and decision-makers.
