Nowadays, we know the Sahara Desert as a place defined by undulating sand dunes, unforgiving sun, and oppressive heat.
But imagine this for a second. Some 10,000 years ago, the Sahara desert was lush, verdant, and green. Yes, it is hard to imagine the desert as a green and woody environment. But there were plants, trees, and greenery all around the desert.
