African deserts gradually disappear, lions are threatened

A study by Duke University showed the deserts in Africa - where lions are considered ideal homes, are disappearing at an alarming rate.

Analyzing images taken from satellites, researchers estimate that about 32,000 lions are living in the deserts of Africa, down about 100,000 from the time of 1960.

The majority of the lion population falls in West Africa, where people have grown rapidly over the past three decades.

Stuart Pimm, a researcher at Duke University, said: "Only about 25% of the system remains in the grass. This is an alarming number because only a few dozen years ago, the environmental system This is three times bigger than America. "

Mr. Pimm also criticized people for using too much land resources and speeding up the construction progress, affecting where lions live.

Also thanks to high-definition images taken from satellites, Mr. Pim and his colleagues still see areas of the lion's favorite in Africa.

According to the image, there are only about 67 distinct savannahs in Africa, where the annual rainfall is about 28cm to 150cm.

However, only about 10 areas are considered "strongholds" of lions, where there is no human presence. Most of these places are in national parks.
