A zoo is a place where captive animals are put on display for humans to see. While early zoos (shorted from zoological parks) concentrated on displaying as many unusual creatures as possible-often in small, cramped conditions-the focus of most modern zoos is conservation and education. While zoo advocates and conservationists argue that zoos save endangered species and educate the public, many animal rights activists believe the cost of confining animals outweighs the benefits, and that the violation of the rights of individual animals-even in efforts to fend off extinction-cannot be justified.
A Brief History of Zoos
Humans have kept wild animals for thousands of years. The capture of exotic animals such as giraffes, elephants, bears, dolphins, and a variety of birds for the purpose of exhibition goes back to ancient Mesopotamia, circa 2500 BCE. The practice began as a show of wealth by private citizens who kept animals in private menageries. Modern zoos began to evolve during the 18th century and the Age of Enlightenment, when scientific interest in zoology, as well as the study of animal behavior and anatomy, came to the fore.
Arguments for Zoos
- By bringing people and animals together, zoos educate the public and foster an appreciation of the other species.
- Zoos save endangered species by bringing them into a safe environment, where they are protected from poachers, habitat loss, starvation, and predators.
- Many zoos have breeding programs for endangered species. In the wild, these individuals might have trouble finding mates and breeding, and species could become extinct.
- Reputable zoos accredited by the Association of Zoos and Aquariums and are held to high standards for the treatment of their resident animals. According to the AZA, accreditation means, "official recognition and approval of a zoo or aquarium by a group of experts."
- A good zoo provides an enriched habitat in which the animals are never bored, are well cared for, and have plenty of space.
- Zoos are a tradition, and a visit to a zoo is a wholesome, family activity.
- Seeing an animal in person is a much more personal and more memorable experience than seeing that animal in a nature documentary and is more likely to foster an empathetic attitude toward animals.
- Some zoos help rehabilitate wildlife and take in exotic pets that people no longer want or are no longer able to care for.
- Both accredited and unaccredited animal exhibitors are regulated by the federal Animal Welfare Act, which establishes standards for animal care.
Arguments Against Zoos
- From an animal rights standpoint, humans do not have a right to breed, capture, and confine other animals-even if those species are endangered. Being a member of an endangered species doesn't mean the individual animals should be afforded fewer rights.
- Animals in captivity suffer from stress, boredom, and confinement. No pen-no matter how humane-or drive-through safari can compare to the freedom of the wild.
- Intergenerational bonds are broken when individuals are sold or traded to other zoos.
- Baby animals bring in visitors and money, but this incentive to breed new baby animals leads to overpopulation. Surplus animals are sold not only to other zoos, but also to circuses, canned hunting facilities, and even for slaughter. Some zoos simply kill their surplus animals outright.
- The vast majority of captive breeding programs do not release animals back into the wild. The offspring are forever part of the chain of zoos, circuses, petting zoos, and the exotic pet trade that buys, sells, barters, and generally exploits animals. For example, an Asian elephant named Ned was born at an accredited zoo, however, he was later confiscated from an abusive circus trainer and finally sent to a sanctuary.
- Removing individual specimens from the wild further endangers the wild population because the remaining individuals will be less genetically diverse and may have greater difficulty finding mates.
- If people want to see wild animals in real life, they can observe wildlife in the wild or visit a sanctuary. (A true sanctuary does not buy, sell, or breed animals, but instead takes in unwanted exotic pets, surplus animals from zoos, or injured wildlife that can no longer survive in the wild.)
- The federal Animal Welfare Act establishes only the most minimal standards for cage size, shelter, health care, ventilation, fencing, food, and water. For example, enclosures must provide "sufficient space to allow each animal to make normal postural and social adjustments with adequate freedom of movement. Inadequate space may be indicated by evidence of malnutrition, poor condition, debility, stress, or abnormal behavior patterns." Violations often result in a slap on the wrist and the exhibitor is given a deadline to correct the violation. Even a long history of inadequate care and AWA violations, such as the history of Tony the Truck Stop Tiger, does not necessarily ensure abused animals will be freed.
- Animals sometimes escape their enclosures, endangering themselves as well as people. Likewise, people ignore warnings or accidentally get too close to animals, leading to horrific outcomes. For example, Harambe, a 17-year-old western lowland gorilla, was shot in 2016 when a toddler accidentally fell into his enclosure at the Cincinnati Zoo. While the child survived and was not badly injured, the gorilla was killed outright.
- Petting zoos have been linked with numerous incidents of diseases including E. coli, cryptosporidiosis, salmonellosis, and dermatomycosis (ringworm).
The Last Word on Zoos
In making a case for or against zoos, both sides argue that they're saving animals. Whether or not zoos benefit the animal community, they certainly do make money. As long as there is demand for them, zoos will continue to exist. Since zoos are likely an inevitability, the best way to move forward is to ensure that zoo conditions are the best possible for the animals that live in captivity and that individuals who violate animal care health and safety sanctions are not only duly punished, but denied any future access to animals.
