Not only are the animals already living away from their natural habitats and in an enclosed space, but they cannot get the right temperature for survival. The Sofia zoo is one of the tourist sites in Bulgaria, therefore, with the animals being in horrible condition, tourists would not come. Lack of tourists would mean that the zoo would not have the money to take care of the zoo and its animal, making it worse. However, the animals are included in our environment, therefore, the cold and lack of heat affects them too.
