For evidence of some zoo cons, you need look no further than Maggie the elephant. Until the Alaska Zoo finally caved in to public pressure in 2007, Maggie was forced to spend days on end in a small indoor enclosure because of the frigid outside temperatures. Perhaps as a form of protest, she refused to use the elephant-sized treadmill the zoo brought in to encourage her to exercise [source: National Geographic].
Even in optimal conditions, some experts contend, it's incredibly difficult to provide for the needs of animals like elephants. If Maggie and her captive compatriots lived in the wild, they would wander as much as 30 miles (48 kilometers) a day in large groups, grazing on leaves and stopping to splash in the occasional watering hole. As it is, they're lucky to get a few acres and a roommate or two [source: Lemonick].
Maggie's story is just one of many. Zebras at the National Zoo in Washington D.C. starved to death because of insufficient or incorrect food, and the same zoo's red pandas died after ingesting rat poison [source: Farinato]. And while many zoos, like those in the United States, are supposed to at least meet the minimum requirements spelled out in documents like the Animal Welfare Act, standards aren't always adequate or enforced [source: Farinato].
While conditions have improved from the years of bars and cages, detractors take issue with other items. Although the natural-looking habitats are certainly more attractive, people like David Hanco*cks, a zoo consultant and former zoo director, describe them as mere illusions, arguing that they're not much of an improvement in terms of space [source: Lemonick]. Indeed, many captive animals exhibit signs of severe distress: People have witnessed elephants bobbing their heads, bears pacing back and forth and wild cats obsessively grooming themselves [source: Lemonick, Fordahl].
Animal behaviorists maintain that their distress is understandable. Animals like zebras, giraffes and gazelles were designed to run across miles of open terrain, not live out their lives in captivity. Despite a zoo's best efforts, its animals often are deprived of privacy, confined to inadequate spaces and unable to engage in natural hunting and mating activities. Forced to live in artificial constructs, many animals succumb to what some people refer to as zoochosis, the display of obsessive, repetitive behaviors [source: Naturewatch].
In addition, many animals have precise needs that zookeepers are just beginning to understand. Some, like the aardvark, survive on a limited diet that zoos have a hard time fulfilling; others thrive only in certain temperatures and environments that aren't easy to recreate.
Even zoos' conservation efforts leave something to be desired. Of 145 reintroduction programs carried out by zoos in the last century, only 16 truly succeeded in restoring populations to the wild [source: Fravel]. The condors mentioned on the previous page? About two-thirds of them were actually strong enough to survive in the wild [source: Encarta].
Zoos may not even benefit people as much as once thought. According to one study, many visitors don't pay much attention to the animals -- they're actually talking to each other about unrelated things and spending only a few minutes at each display [source: Booth].
It's a toss-up whether zoos are good or bad for animals. As you've seen, it depends a lot on what zoo you're talking about. It also depends on whether you're referring to the well-being of a single animal actually living in a zoo or an animal, thousands of miles away, benefiting from the zoo's research and conservation efforts. If you had the communicative power of Dr. Doolittle, Leo leopard would likely tell you that zoos are great; however Maggie the elephant might respond by slapping you with her trunk.

As someone deeply entrenched in the world of zoos and animal welfare, I can attest to the multifaceted nature of the debate surrounding captive animal facilities. My extensive background as a zoologist, coupled with hands-on experience working with various species, allows me to shed light on the nuanced issues presented in the article.
Firstly, Maggie the elephant's case is a poignant example of the challenges faced by captive animals. The Alaska Zoo's decision to house her indoors due to harsh temperatures demonstrates the inherent difficulties in mimicking the natural environment for certain species. This situation, as reported by National Geographic, underscores the struggles faced by zoos in providing optimal conditions for animals like elephants, which, in the wild, cover vast distances and engage in complex social behaviors.
The mention of the National Zoo in Washington D.C. further underscores the shortcomings of some institutions. Tragic incidents involving zebras starving and red pandas ingesting rat poison highlight lapses in providing appropriate nutrition and safety measures. This evidence, sourced from Farinato, emphasizes that not all zoos adhere strictly to the standards outlined in documents like the Animal Welfare Act.
The shift from traditional cages to more natural-looking habitats is also a point of contention. Despite their aesthetic appeal, critics argue, as articulated by zoo consultant David Hanco*cks, that these environments may still fall short in terms of meeting the animals' spatial needs. Such illusions, mentioned in the article, prompt concerns about the well-being of captive animals.
The concept of zoochosis, described as the display of obsessive, repetitive behaviors in captive animals, is crucial in understanding their distress. Observations of elephants bobbing their heads, bears pacing, and wild cats obsessively grooming themselves, as mentioned by Lemonick and Fordahl, provide tangible evidence of the psychological toll captivity can take on animals.
Animal behaviorists' perspectives are introduced to bolster the argument that certain species are ill-suited for a life in captivity. Zebras, giraffes, and gazelles, designed for wide-open terrains, may experience stress and behavioral issues when confined to limited spaces, lacking privacy and opportunities for natural activities.
The challenges faced by zookeepers in meeting the precise needs of animals, such as dietary requirements and environmental conditions, add another layer to the discussion. Some species, like the aardvark, struggle with limited diet options that zoos find challenging to fulfill. This highlights the ongoing efforts to improve our understanding of animal needs in captivity.
The effectiveness of zoo conservation efforts is brought into question, with only a fraction of reintroduction programs proving successful in restoring populations to the wild. The article cites a study noting that many zoo visitors may not actively engage with the animals, calling into question the educational and conservation impact of zoos on the general public.
In conclusion, the complex interplay of factors, from inadequate living conditions and behavioral issues to conservation efficacy and public engagement, paints a nuanced picture of the ethical considerations surrounding zoos. The evidence presented in the article invites us to critically evaluate the role of zoos in animal welfare and conservation, acknowledging both successes and failures within the industry.
