"...if you ever try the sweet water from Vrana Lake, you shall surely return..."

Urbanization of previously untouched parts of nature caused an escalation of disruptions. Even the most remote islands were not spared, in fact, they remained the most susceptible to such pressures. The conviction that prevails in science today is that animals that live on the islands form an individual, specific colony of inhabitants. For this reason and due to geographic isolation, many endemic animal species have developed on the islands. At the same time, more and more species die off sooner on the islands than on the mainland. Therefore islands are among the most endangered areas from the standpoint of conservation of the world's biological diversity.
