The Javan rhinoceros, an endangered species, no longer exists in Vietnam: poachers killed the last one and took its horn, according to the World Wildlife Fund.
That rhinoceros was killed last April and since then there have been no signs (viewings, scat, etc.) of any others remaining in the Cat Tien National Park where they used to live. As many as 60 rhinos remain outside of Vietnam, living in Indoneisa's Ujung Kulon National Park, so the entire species isn’t extinct yet. But it’s super, super endangered.
Demand for ground-up rhino horn, used as a curative, drives poaching. That last Vietnamese rhino horn better have cured cancer. Otherwise, this story would be beyond sad.
