A new report shows that there are just 7,100 cheetahs now left in the wild. Cheetahs are in trouble now.

According to the study, more than half of the world’s surviving cheetahs live in one zone that covers six countries in southern Africa. Cheetahs in Asia have nearly died out. It’s thought that only fewer than 50 cheetahs live in Iran.

The cheetah runs across lands far outside protected areas. Some 77% of their habitat falls outside these protected areas. As a result, the cheetah struggles because these lands are increasingly being developed by farmers and the cheetah’s food is decreasing because of human hunting.

In Zimbabwe, the cheetah population has fallen from around 1,200 to just 170 in 16 years, with the main cause being major changes in land ownership.

Researchers say that the threats cheetahs are facing have gone unnoticed for far too long. “Given the nature of the cheetah, it has been difficult to gather information on them,” said Dr Sarah Durant, the report’s lead author. “Our findings show that the large space requirements for cheetahs and various threats faced by them in the wild mean that they are likely to be in danger of dying out.”

Another big concern about cheetahs has been the illegal trafficking (非法交易) of young cheetahs. The young cats can fetch up to $10,000 on the black market. Some 1,200 young cheetahs are known to have been trafficked out of Africa over the past 10 years but around 85% of them died during the journey.

If the cheetahs are to survive, then immediate efforts must be made.
