There are numerous endangered animal species in the world, including the Amur leopard, Sumatran orangutan, black rhinoceros, vaquita, and mountain gorilla. To protect them, conservation efforts must focus on habitat preservation, anti-poaching measures, combating illegal wildlife trade, implementing strict regulations, promoting community involvement, and raising awareness to garner support and funding for conservation initiatives. Collaborative efforts between governments, organizations, and local communities are essential for the long-term protection and recovery of these species.
