When it comes to desert, many people think of terror and the unknown. With the arid climate and changeable weather, desert has become the most mysterious landscape in nature. Many people are curious and afraid of desert. With the deepening of scientists’ research, scientists have found that even in the desert with bad environment, human ancient civilization has been preserved. As the largest desert in the world, the Sahara desert has left a lot of civilization wealth to mankind. Some scientists once discovered mysterious murals in the Sahara desert. It turns out that the Sahara Desert used to be a green plain.

In 1850, the German chief Explorer discovered traces of murals in the Sahara desert. As soon as the news came out, it immediately attracted the attention of the scientific community. Every year, many scientists came here to explore, hoping to unravel the secrets of these murals. In these murals, we can see animals such as cattle and horses, which are tied with ropes, and human beings are chasing them. Therefore, scientists infer that since there is such a farming phenomenon, it means that the Sahara was a plain land before.

We can see that there are many kinds of animals in the murals, from cattle and horses to adoption and giraffes. These rich natural species appear vividly in front of people. It seems that we can see the way of human existence at that time through these murals. According to the in-depth research of scientists, these murals all reflect the living footprints of human beings in that era, but scientists can not give an accurate explanation about the time and time of these pictures.

In addition to murals, there are many river relics in the Sahara desert. Through the exploration of these river relics, scientists found that there are many biological fossils in the depth of these relics. The discovery of these fossils is of great significance to scientists. Scientists believe that these fossils of animals and plants show that the Sahara was not only a green plain, but also a very rich water area. The Sahara was once a vibrant scene.

Therefore, scientists judge that these murals should have been born before 7000 BC. At that time, the Sahara was still a favorable environment for survival. At that time, the Sahara had a warm climate and abundant rainfall. It was not until 4000 years ago that the ecological environment evolved into today’s desolate scene.

There are two kinds of voices in the scientific community about the evolution of the Sahara environment. One is that the natural environment has changed, and the other is that the vegetation has been destroyed due to the excessive deforestation of human beings. After a long period of evolution, it has gradually formed a desolate scene of naturalization. What do you think caused the environmental change in Sahara?
