It classifies species into nine categories, from Not Evaluated to Extinct, and provides data and news on biodiversity conservation.

An endangered species is any species that is at risk of extinction because of a rapid decrease in its population or a loss of its critical habitat.
What role does human activity play in causing species to become endangered?
Roughly 99 percent of threatened and endangered species are at risk because of human activities. The principal threats are habitat loss and degradation, the spread of invasive species, the growing influence of global warming, chemical pollution, unsustainable hunting, and disease.
What organizations determine which organisms are endangered species?
Among the organizations connected with assessing which organisms are endangered species are the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the Convention on the Conservation of Migratory Species of Wild Animals (CMS), and the Red List of Threatened Species, created by the International Union for Conservation of Nature (IUCN).
endangered species, any species that is at risk of extinction because of a sudden rapid decrease in its population or a loss of its critical habitat. Biodiverse regions that require protection on the grounds that they host a significant number of endangered species are called hot spots.
Roughly 99 percent of threatened species are at risk because of human activities alone. By the early 21st century it could be said that human beings (Homo sapiens) are the greatest threat to biodiversity and are the major drivers of biodiversity loss. The principal threats to species in the wild are:
1.Habitat loss and habitat degradation
2.The spread of introduced species (that is, non-native species that negatively affect the ecosystems they become part of)
3.The growing influence of global warming and chemical pollution
4.Unsustainable hunting
5.Disease

An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change .
The IUCN Red List is the world’s most comprehensive information source on the extinction risk status of animal, fungus and plant species. It provides data, trends, categories, metrics and conservation actions for thousands of species, and is updated every year.
