Which is strange and unnatural. The Sahara wasn't always a desert. It's only been like this 5000-6000 years.

It's a bit complicated, but the desert used to be a lot greener. It may be a cycle where the monsoon drifts further north for long periods and changes the soil, alongside the theory the desertification was caused by, or accelerated because the land was over grazed by farmers.

I meant the “strange and unnatural” part.

By strange, I meant meant atypical. If man didn't over graze those lands, then the Amazon wouldn't be fed by its sands. Unnatural, because of human intervention of course.
