The mystery of nature

Some fields Namibia and Angola can observe a curious phenomenon: numerous round spots dot the barren land, these spacious plains. This phenomenon was discovered back in 1971, but still an adequate explanation for his net.

The diameter of the spots ranges from two to fifteen meters, and the total amount for a long time in the thousands. There is a phenomenon only in lands distant from large population centers, so a large group of enthusiasts that created this myth, and for many years it supports, however.

According to legends Himba people who live in Namibia, the circles are due to fire-breathing dragon that lives under the Earth's crust. Other, more realistic hypothesis put forward by scientists believe that the cause of this phenomenon lies in the work of ants, or plants, or due to the influence of toxins and chemical waste.

The most convincing explanation by the German biology professor Norbert Jürgens (Norbert Juergen), alleges that the stains caused by complex sand termite activity. According to him, these insects devour all vegetation within a small circle and buried in the ground. The lack of vegetation allows moisture to seep through the sand, so that even in the driest conditions underground termites preserved a small pool of water.



Biologist Walter Schinkel (Walter R. Tschinkel) held an "independent investigation" of mysteries origin spots, but no traces of termite activity in them is not found. Scientists debate about the origin of crop circles in Namibia and continues to the present day, and the unsolved mystery only adds spice to pictures taken in those places.
