The Red List, maintained by the International Union for Conservation of Nature (IUCN), provides information on endangered plants and animals. It assesses the conservation status of species and highlights those at risk of extinction.

Wildlife conservation involves both ex-situ and in-situ conservation methods. Ex-situ conservation refers to the preservation of species outside their natural habitats, such as in zoos or botanical gardens. In-situ conservation refers to the protection of species within their natural habitats, such as through the establishment of protected areas like national parks.

The primary cause of the extinction of wildlife is the destruction of habitat. When natural habitats are destroyed due to human activities such as deforestation, urbanization, and agriculture, species lose their homes and sources of food, leading to decline in their populations and eventually extinction.

National parks are areas that are strictly protected for the conservation of wildlife and their habitats. They provide a safe environment where plants and animals can live and reproduce without the threat of poaching, habitat destruction, or other human disturbances.
