Planet Earth fact

The Sahara was green a few thousand years ago.

The details

Between roughly 11,000 and 5,000 years ago, the Sahara had lakes, grasslands and animals like hippos. Rock art in the desert shows cattle and swimmers. Shifts in Earth’s orbit changed the monsoons and dried the region out.
