Fairy Circles

This is a natural mystery that defies explanation. In the dry and arid grasslands of South Africa, circular patches called fairy circles appear. They range between 2 and 15 metres (7 and 49 feet) and scientists are puzzled as to where they come from, and why just that small area is made barren. Some say sand termites, some say other factors cause the land in that small area to lose its vegetation, but to date, there’s no definite explanation.
