Grenny’s Tooth (Babin zub in Serbian) is a part of Stara planina, or Balcan mountain, situated in Eastern part of Serbia, and spreading across Bulgaria all the way to the Red sea. Its pristine nature, and geology ware the main argument for protecting this part of mountain by Serbian ministery. On the other hand, this uniqueness is the main argument for developing ski turism, which already couse some species to dissapear from Babin zub. Many people has passed through this region, exploating natural resources over the centuries, but withough major impact on living creatures. It is sad that our inspipration for this aquascape can be changed once and forever.
