非洲的撒哈拉大沙漠总会使人想起干旱、贫瘠和荒凉的画面。然而,是不是盘古开天地以来,它就是一望无际、了无人烟的沙漠呢?历史上的撒哈拉沙漠究竟是什么样子?德国科隆大学的地质考古学家Stefan Kropclin通过对东撒哈拉长达30年的挖掘,以及对其出土的文物,例如动物骨骼、山洞艺术品等研究,对以上问题给出了明确的答案。他认为,过去的撒哈拉大沙漠曾是一个生机勃勃的绿色伊甸园,将来它必将重现昔日草木葱茏的景像。 The Sahara desert in Africa always reminds people of the drought, poverty, and desolation. However, since the beginning of the ancient world, is it an endlessly deserted desert? What was the history of the Sahara desert? The geological archaeologist Stefan Kropclin of the University of Cologne in Germany passed a 30-year excavation of the East Sahara. And the research on unearthed cultural relics, such as animal skeletons and cave art, gave clear answers to the above questions. He believes that the Sahara desert in the past was once a vibrant green garden of Eden. In the future, it will surely recreate the scenes of past greenery.
