Habitat is the driving force in the evolution of any animal species. Indeed, the
evolved animal is a direct reflection of the natural habitat within which it is typically
found. In zoos, we remove animals from their natural habitats and put them into ones
that are foreign to them. When we place these animals into captivity, there are many
biological consequences. Primarily, the animals deal with a lot of stress, resulting in
stereotypic behaviors. These behaviors are a reflection of animals’ poor welfare when
placed in a captive environment. While zoos do benefit the planet in some ways, these are
strongly outweighed by the harm caused to the animals in captivity.
