Why There's So Much Sand in the Sahara

Or... who ate the cedars of Lebanon?
In the vast Sahara, seas of sand ripple for miles. They rise up in wavelike dunes that can crest at over 1,000 feet. With temperatures that have been known to reach 136°F (58°C), the desolate Sahara covers most of North Africa and over a third of the African continent. It's the world's largest desert, home to over three million square miles of dust, stone, and sand.
In the sweltering Sahara, a cool vision of waving grass and shining lakes can seem like a mirage (or the first signs of heat exhaustion), but it's a glimpse into the Earth's astounding past. Hard to believe, but this hostile ocean of sand was once an earthly Eden. Fish swam in ancient lakes; giraffes, elephants, and gazelles roamed grassy savannas; and hippos wallowed in ponds and mud.

10 Weird Reasons Why Women Got The Vote
Happy Women’s Equality Day! On August 26, 1920, the 19th Amendment became law, and American women gained “suffrage,” which simply means they got to vote.

10 Ways Animals Are Geniuses
In 1960, Jane Goodall shook up the human view of primates when she discovered a chimpanzee stripping twigs and poking them into termite mounds so that he could fish out tasty bugs for dinner.
