What are the advantages of wildlife sanctuaries to zoos?

Wildlife sanctuaries offer several advantages over zoos, primarily focusing on animal welfare and conservation. Sanctuaries provide a more natural habitat for animals, allowing them to engage in instinctual behaviors and live in a less stressful environment. They often prioritize rehabilitation and release of animals back into the wild, promoting species preservation, while zoos typically emphasize education and entertainment. Additionally, sanctuaries can foster biodiversity by protecting larger areas of land and supporting ecosystems, whereas zoos are usually limited in space and resources.
