Zoo

A zoo (short for zoological garden; also called a zoological park, animal park, or menagerie) is a place where animals live in enclosures so people can see them. Zoos also help with conservation, which means helping animals and their homes.

The words zoological garden come from zoology, which is the study of animals. They are based on old Ancient Greek words. The word zoo was first used for the London Zoological Gardens, which opened in 1828. The first modern zoo was the Tierpark Hagenbeck by Carl Hagenbeck in Germany. Many people visit zoos every year.

Some animal welfare organizations have concerns about how animals are treated in zoos. They worry about the places where animals live and how visitors act. Because of this, many zoos are working to make things better for the animals.

Etymology

The word "zoo" comes from an old Greek word for animal. The London Zoo opened in 1828 and was first called the "Gardens and Menagerie of the Zoological Society of London." People began using the short name "zoo" around 1847, especially for the Clifton Zoo.

Later, new names like "conservation park" or "bio park" were created to show a modern way of caring for animals. The National Zoo in Washington D.C. helped create the term "bio park" in the late 1980s.

History

Royal menageries

Further information: Menagerie

The earliest versions of zoos were called menageries. They date back to ancient times. One of the oldest known animal collections was found in Hierakonpolis, Egypt, dating to around 3500 BCE. It included animals like hippos, elephants, and baboons. Kings and emperors across different cultures, such as King Wen of Zhou in ancient China and Alexander the Great in Greece, also kept animals. During the Roman Empire, animals were often kept for public spectacles.

The world’s oldest zoo still in operation is the Schönbrunn Zoo in Vienna, Austria. It opened in 1752 for the royal family but began allowing public visits in 1765. Other early zoos included ones in Madrid and Paris, which opened in 1775 and 1795 respectively. These zoos focused on science and learning.

The modern zoo

By the 19th century, zoos changed from private royal collections to public places for learning and science. Major cities in Europe, inspired by zoos in London and Paris, opened their own. The Zoological Society of London founded London Zoo in 1828, which became a model for zoos worldwide.

British Empire

The modern zoo in the United Kingdom focused on learning and science. London Zoo was the world’s first scientific zoo and opened to the public in 1847. Other notable zoos in the British Empire included Dublin Zoo and Whipsnade Zoo. The first zoo in Australia was Melbourne Zoo, opening in 1860.

Germany

Important early zoos in Germany included those in Berlin, Frankfurt, and Hamburg. Carl Hagenbeck in Hamburg introduced open enclosures with moats instead of bars, allowing animals more natural spaces.

Poland

The Wrocław Zoo is the oldest in Poland, opening in 1865. It is known for its large collection of animals and its Africarium, which focuses on African wildlife.

United States

The first zoo in the United States was the Philadelphia Zoo, opening in 1874. Other early zoos included those in Chicago and Cincinnati. During the 1930s, government programs helped zoos grow. By 2020, the U.S. had many accredited zoos and aquariums.

Japan

Japan’s first modern zoo, Ueno Zoo in Tokyo, opened in 1882. During World War II, it was used for learning, and some animals were treated differently due to fears of bombing.

Environmentalism

In the 1970s, zoos began focusing more on protecting nature. Many stopped animal shows and started breeding programs for animals in danger. Today, zoos work to protect wildlife and teach visitors about nature.

Human exhibits

In the past, some zoos displayed humans in ways that compared them to animals, often to show differences between races. One famous example was in 1906 when Ota Benga, a Congolese man, was displayed in the Bronx Zoo in New York City. These displays were controversial and are now seen as wrong.

Zoo animals live in special spaces made to look like their natural homes. These spaces help both the animals and visitors. For example, animals that are active at night might stay in buildings with dim lights during the day so they can be seen when people visit. Some zoos have areas where visitors can walk among gentle animals like small monkeys or birds.

Some zoos have large outdoor areas called safari parks. Visitors can drive through these areas and see animals up close, sometimes even feeding them through car windows. The first safari park opened in England in 1931. Other popular places mix zoo exhibits with fun rides and shows, creating animal theme parks that are both educational and fun for families.

Zoo population management

Most animals in zoos today are born in zoos from other zoo animals. When animals move between zoos, they spend time in quarantine and get used to new enclosures that look like their natural homes. Some animals, like penguins, need special cold enclosures.

Zoos manage their animal populations carefully because space is limited. They work with groups like the Association of Zoos and Aquariums and EAZA to make sure healthy animals are kept and to prevent inbreeding. Some zoos use contraception to control breeding. Zoos sometimes have to make tough decisions about animal care, balancing what’s best for the animals with what’s possible in a zoo setting.

Many animals breed easily in captivity, but zoos often need to limit breeding because there isn’t enough wild habitat to release them into. This shows why protecting natural spaces is important, along with zoo breeding programs.

Justification

Most modern zoos in Australasia, Asia, Europe, and North America work to protect animals that are in danger. They also do research and teach people about animals. These zoos want to entertain visitors, too.

Zoos help keep animals safe when it is hard to protect them in the wild. They give these animals a safe place to live and have babies. This is important for animals that could disappear. Zoos work with programs all over the world to help endangered species. These programs make sure animals are well cared for and that there are more of them.

The care of animals in zoos can be different at different zoos. Some zoos work hard to make sure animals have comfortable and safe homes. This can be hard because of space and money. Good homes help animals live longer and healthier lives.

When zoos focus on animal care, they can become safe places for animals. Many zoos add things to animal habitats to help animals act more naturally. This makes the animals happier and healthier.

Sometimes, zoos need to move bigger animals to places with more space. Even with good care, keeping animals in zoos can be tricky because animals deserve to be free. Groups like EAZA and AZA create guides to help zoos take better care of animals.

Problems

Modern zoos work hard to keep animals healthy and happy. But some zoos still have problems. In places with fewer rules, some animals, like apes, do not live long in captivity. Some zoos also keep animals in small spaces where they cannot move around much.

Animals in zoos can sometimes show unusual behaviors, like pacing back and forth. This might mean they are feeling stressed. But newer exhibits help reduce these behaviors. Some studies show that animals in zoos can live longer than those in the wild. This depends on the species and care. Climate can also affect zoo animals. For example, cold weather made it hard for an elephant at the Alaska Zoo to stay outside.

Effect of visitors on animals

Visiting a zoo can affect animals in different ways. When there are too many visitors or when they are noisy, animals can feel stressed. Animals like rhinoceroses and primates sometimes show signs of stress when many people are around.

Some animals seem to enjoy having visitors nearby. For example, a long-billed corella named Claude liked to dance and walk when people were close. Animals such as prairie dogs and chimpanzees can find interactions with visitors positive, especially when they can choose to hide if they feel uncomfortable. Keeping visitor numbers low and creating calm environments helps keep animals happy and healthy.

Moral criticism

Some people worry that zoo animals are treated like things to look at, instead of living creatures. They think animals might suffer when taken from the wild and put in zoos. Since the 1970s, zoos have changed how they care for animals. They now breed animals instead of taking them from the wild. This helps protect animals that are in danger of disappearing.

In 2017, a survey in the UK found that many people thought zoos spent more on helping animals than they really do. Because of worries about how animals are treated, a travel company chose to stop promoting trips that include visits to zoos.

Live feeding

In some places, it is against the law to give live animals to zoo predators to eat, unless it is needed for the animal's health. For example, the UK Animal Welfare Act of 2006 says that prey must be killed before being fed. London Zoo stopped this long before the law. However, some zoos in China still give live animals to predators, which has caused criticism. Some parks, like Shenzhen Safari Park, have stopped this after facing criticism.

Regulation

In the United States, zoos must follow rules set by groups like the Department of Agriculture, the Environmental Protection Agency, and the Occupational Safety and Health Administration. Zoos follow laws such as the Endangered Species Act, the Animal Welfare Act, and the Migratory Bird Treaty Act of 1918 to keep animals safe.

In Europe, the European Union says zoos should help protect wildlife and teach people about animals. The UK has rules too, making sure zoos are checked and give animals a good home.
