Answer:
Over the last decade, hunting has claimed the lives of 7100 rhinos. Every day, that's the equivalent of two rhinos!
Rhino horns are sold at extravagant prices due to exceptionally high demand and extremely limited supply. This has resulted in a significant rise in funding for hunters, allowing them to become far more sophisticated in their hunting techniques.
Helicopters are sometimes used to detect rhinos. They'd use weapons or tranquilizers to shoot the rhino down from the sky. Soon after, hunters land and use chainsaws to quickly remove the rhino's horns before flying away. The entire operation takes less than 10 minutes, and the rhino is either killed or severely damaged.
Rhinos with severe head injuries (due to horn removal) have a low chance of survival. Rhino horn that has been processed (ground) is used in traditional Asian medicine to treat a variety of ailments ranging from cancer to hangovers. Possession of rhino horns is regarded a prestige symbol in some Vietnamese societies.
