If the sea level had remained the same throughout history, we would have no submerged islands today.
The sea level has both risen and fallen. The climate has always changed. The Sahara Desert was once a woodland.
This way, 6,000-8,000 years ago, the rainfall was abundant, and in Sahara flourished the Neolithic culture which left the famous rock paintings found in Tassili n'Ajjer Mountains (above) and other areas of Sahara, depicting crocodiles, ostriches, rhinos, giraffes, buffaloes, hippopotamus and elephants, encountered today only in Africa at South of Sahara, but also oryx antelopes and gazelles. The Sahara was filled with lakes in the region of modern Niger and people hunted antelopes, while its mountains were covered by forests. Archaeologists encountered from hippopotamus and elephant bones to fishing harpoons.
Has Sahara Always Been a Desert?
The worse damage might be trying to stop natural climate change since we just don't know what the **** we are doing when we do that.
