Species like the **Amur leopard**, **Javan rhinoceros**, **Vaquita porpoise**, and **Sumatran orangutan** are on the brink of extinction due to deforestation and illegal hunting. Conservation efforts, including protected areas, anti-poaching measures, and breeding programs, aim to save these species.
