What Really Turned the Sahara into a Desert

The Sahara wasn’t always the endless sandscape we know today—it used to be lush and green! 🌿 Around 6,000 to 7,000 years ago, it was covered in grasslands, rivers, and even lakes, supporting animals like elephants and hippos. Scientists say the shift happened because of changes in the Earth’s orbit, which messed with the monsoon rains that kept the region fertile. As the rains moved south, the Sahara dried up, turning into the desert we see now. But what’s really wild is that this cycle of greening and desertification has happened multiple times over millions of years. Who knows—maybe the Sahara will be green again someday! 🌎
