Behavioural disturbances
Living in a zoo deprives animals of their freedom and entails several threats to their health and wellbeing. Confined spaces and insufficient amounts of stimuli can lead to stereotypical behaviours, in other words, behavioural disturbances. For instance, rocking from side to side, pacing or walking in circles. This can affect animals who cannot exhibit their natural behaviours in captivity, such as animals belonging to species that roam across vast areas in the wild, like elephants(2) or dolphins.
In addition, many of the species of animals kept at zoos in Nordic countries are adapted to a completely different climate than the one they are kept in. Because of this, these animals are kept inside during the winter season, further limiting their environment.(3, 4) Examples of species like this are elephants and chimpanzees.
