Assessments place 28 percent of evaluated animal species at risk of extinction. Habitat destruction drives the majority of these losses. The following sections detail current rates along with documented recoveries from targeted interventions.
Key Takeaways
- Protected areas cover only 17% terrestrial/10% marine habitats, preventing 29% extinctions (Science 2023)
- The IUCN Red List assesses that 28% of all evaluated animal species (over 47,000 species) are threatened with extinction as of 2024
- Since 1500, 680 vertebrate animal species confirmed extinct (IUCN 2024)
- Habitat destruction accounts for 85% of assessed animal extinctions (IUCN 2023)
- 27,974 of 150,000+ described animal species threatened (IUCN 2024)
Many animal species are declining, and urgent action is needed to stop extinctions from accelerating.

Conservation Efforts and Projections Interpretation
The statistics show that while we are still tragically playing whack-a-mole with extinction, our growing toolbox of conservation strategies—from high-tech gene banks to old-fashioned protected areas—is proving we are not just chroniclers of decline but increasingly effective architects of recovery.

Interpretation
Historical Extinctions Interpretation
