According to the IUCN Red List, as of 2021, around 30% of mammal species are categorized as threatened with extinction, compared to approximately 12% of bird species, 25% of amphibians, and 36% of reptiles. While the percentage of plants in danger of extinction is high, it is difficult to compare with animal groups as there are significantly more plant species, and many have not been fully assessed for their conservation status.
