No, These Are Not Trees

In an Israeli city, Yeruhan, which is located in the middle of the Negev desert, there are hills over 15 meters high. And no! These aren't covered with trees or grass!

This is actually broken glass! This is the place where thousands of old glass bottles come in everyday and are left here to be recycled.

When you first look at them, they look like any other hills, but when you get a little bit closer you realize the scary yet beautiful truth.
