Zoos: The Historical Debate

(ZOOS/ANIMAL WELFARE) For centuries people have flocked to zoos to see wild animals up close. The first zoo was established in 1748 in Vienna, Austria, and is still entertaining people today. But many believe that keeping an animal in a simulated habitat is not in their best interest, citing issues of animal welfare and conservation.

Are zoos harming these animals by keeping them caged up, or are they helping conserve animals on the brink of extinction? Read on for both sides of this historical debate, told from the perspective of an animal rights activist. — Global Animal

How Stuff Works, Jennifer Horton

Humans have an insatiable fascination with wild animals. Every year, millions of people go on safaris, board whale-watching cruises and watch Jeff Corwin get attacked by snakes on Animal Planet; others drive to their localzoo for a full day of animal gazing.

This interest in animals is nothing new: Zoos have been entertaining people with exotic animal collections as far back as 1250 B.C. [source: Fravel]. Later, in early 13th-century England, Henry III moved his family’s royal menagerie to the Tower of London for public viewing. For a small fee, visitors would be treated to glimpses of animals like lions,camels and lynxes. And if they brought a dog or cat to feed the lions, they got in for free [source:Encarta].

The first modern zoo — the Imperial Menagerie in Vienna, Austria — was established in 1752 and continues to attract visitors to this day. Nearby, in Germany, is the world’s largest animal collection: Zoo Berlin (formerly The Berlin Zoological Gardens) houses more than 15,000 animals from almost 1,700 species [source: Encarta].

All U.S. animal exhibitors, like the 265-acre (107-hectare) Bronx Zoo just a subway ride away from Fifth Avenue, must apply for and receive a license from the Department of Agriculture. Millions of people visit the thousands of zoos around the world, proving that we simply never grow tired of observing wildlife.

Depending on your point of view, though, zoos are either sanctuaries of education and entertainment or unnecessary prisons. While some people argue that zoos play an important role in conservation and research, others counter that they do more harm than good.

So which is it? Are zoos good or bad? And how do you differentiate between what’s good for one animal versus what’s good for the entire species? It’s a delicate question and one that can’t easily be answered. Let’s start with the good news.

Zoo Pros: Education, Conservation, Entertainment

Zoos have improved significantly in the last 4,000 or so years. Gone are the old steel-bar enclosures and cold cement cages. Most zoos these days use natural-looking barriers like moats or ditches to separate animals from people, and have mini-habitats that resemble the animals’ natural environment.

Adding another point for zoo pros, the procedure for acquiring animals has also changed. Whereas zoos previously captured most of their specimens directly from the wild, they now get many animals through captive breeding programs and other zoos. Some breeding programs also help to restore threatened species. After 10 years of working to strengthen the population numbers of the endangered California condor, a type of vulture, the Los Angeles and San Diego zoos were able to rebuild a population of fewer than two dozen birds to around 170 birds [source: Encarta].

Successful breeding programs brought the Pere David’s deer back from extinction. Though this Asian deer ceased to exist in the wild, Chinese and European zoo programs enabled four of the deer to be released back into the wild in 1985, where they’re now self-sustaining [source: Encarta].

Some zoos also take in abandoned animals that wouldn’t otherwise have a home. Both the Baltimore Zoo and the Detroit Zoo have taken in polar bears rescued from a traveling circus, and the Bronx Zoo took in an orphaned snow leopard from Pakistan in 2007. The cub, Leo, now spends his time frolicking and chasing small animals that wander into his enclosure [source: Majkowski].

And although zoo animals aren’t treated quite like guests at a four-star hotel, their care has improved tremendously. Zookeepers now understand that many animals, such as monkeysbears and elephants, need engaging activities to prevent boredom and mental deterioration. This is why you’ll often see chimps playing with toys or tigers “hunting” for a meal.

Aside from taking care of captive animals, many zoos also contribute to the care of their wild counterparts. The Toledo Zoo, in conjunction with the Nature Conservancy, is helping to restore butterfly habitats in Ohio, and the Bronx Zoo has channeled more than $3 million toward conservation projects in central Africa [source: Fravel].

Zoos also present an opportunity for scientists to conduct research. In 2002, zoos participated in 2,230 research and conservation projects in more than 80 countries. The information they gather helps them to develop new medicines and techniques to improve animal health [source: Fravel].

Beyond the positive impact zoos try to have on animals, they often affect the people visiting as well. Zoos don’t just entertain, they also aim to educate. With a variety of programs geared toward children and adults, zoos teach people about the needs of animals and the importance of conservation. And if people get excited enough, the thinking goes that they’ll be more inclined to donate money to conservation efforts — another zoo pro.

The fact that zoos impact people in a positive way is nice, but it’s not the people critics worry about — it’s the animals.

Zoo Cons: Wild Animals Are Meant to Be Wild

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 Hancocks, 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 zebrasgiraffes 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 the snow leopard would likely tell you that zoos are great; however Maggie the elephant might respond by slapping you with her trunk.

    Coin grade is a major factor that determines
    the price of gold and silver prices on demand price paid by bullion dealers at coins stores for the metal either.
    Both sides of a French rooster coin is the only
    medium that enables a retail client to purchase gold and rosland capital silver keep going up unremittingly?

    I actually worked at a wildlife park/animal sanctuary for 2 years and have visited many zoos around the country. While not as "entertaining" for people, I have a lot of respect for the zoos that create habitats that cater to animal, rather than the people…ie that offer privacy and seclusion at the cost of visitors ability to get a good look at them. My own zoo, my biggest complaint is some of the enclosures. While they met state requirements, they left something to be desired. The lion, tiger, bear, baboon, and monkey enclosures were really just too small. But, the animals were well loved and well cared for otherwise. I actually bottle raised quite a few exotic babies for them, and whether my responsibility or not, I can honestly say that I loved each and every animal in that park as much as my own pets at home. So, before judging zoos too harshly (the good ones, at least), do know that the majority of employees truly love and do their best to care for the animals in their charge. We care about educating and engaging the public and ensuring our animals are happy and healthy. There are of course bad apples in ever walk of life, but to work a job as zoo keeping and animal handling, you HAVE to love them and love what you do…otherwise going home covered in pee, baby formula, dirt, excrement, and drool wouldn't be worth it :p.

    Good for us as we get to know closely the animals that are rarely seen and bad for the animals as there freedom is lost when they are in zoo, sitting in cage for whole day is just like being in hell for them.

  5. we say “no” to zoos/circuses, but a big paws up, “yes” to animal sanctuaries…especially those for endangered species!

    Of course it’s not in the animal’s best interest. The best thing I can say about zoos is that they are not as bad as circuses.
