Zoos are popular for hundreds of years, introduced a variety of animals to visitors who otherwise would never have seen them. Based on the ‘History of Zoos’, the first and the largest zoo was revealed by ancient Egyptians at around 3,500 bc. The animals such as hippopotamus, elephants, baboons and wildcats had been found in the zoo. At that time, the wild animals had been captured as demand of pharaohs for retaining their enjoyment. This acted as an intimidation of enemies or to hunt in a controlled setting as a way of showing their wealth and power. Times change, however, and people must question whether zoos are still relevant in a world where they wish to treat animals humanely. Although animals are safe in the wild in their own natural habitat, it is still more true to say that animals should be kept in captivity, like in a zoo, because they can be better looked after by humans and prevent the extinction of animals.
Firstly, the animals are safer in captivity as the protection will be given to the animals since the humans will take care of them. Humans have realise that it is important to protect animals to maintain the planet’s biodiversity. The richness of animals and plant life with their abundance and wild habitats keep all healthy and happy. Since 1822, the United Kingdom which was the first country in the world to implement law protection animals. Elephants and rhinos were saved by UK soldiers who are heading for Africa to pass on their battleground. (Winter 2018)When the planet is moving into a technology era, humans develop new technology to comfort animals in the zoo as the artificial intelligence (AI) experiment which can save the zoo thousands years to keep the zoo animals warm as installing the thermal sensor and control the temperature in the zoo by the AI computer (Kleinman 2017). According to Victoria Grill (2018), a research published in the journal Current Biology revealed that more than 100,000 Critically Endangered orang-utans have been killed in Boneo since 1999. This research proves that without the protection of humans, the animals are losing their protection and staying in the captivity will easier to humans to take care of them.
Besides, animals are safer in zoo to prevent them from extinction because under protection of humans the amount of animals will increase. According to a new analysis in BBC News, the largest and the smallest of the world’s animals, on land and in water, are most at risk of extinction. The more species disappear, the more entire eco-systems become vulnerable and would eventually fall apart as the links in the food chains become broken. According to Dr Tom McCarthy, the snow leopards have been changed from “endangered” to “vulnerable” which announced by the International Union for Conservation of Nature (IUCN). This proves that humans are acted an important role to prevent extinction of animals. Pangolin have been classified as the IUCN Red List of Threatened Species since 2014 (Briggs 2017). Based on the research in the journal Conservation Letters as estimated since 2000, more than on million pangolins have been traded illegally at the international level. A non-profit project, Save Pangolins, has increased the capacity of conservation on the ground where pangolins live. Climate change is one of the role of nature in the wild and it cause the extinction of animals (Tudge 1992). For example, the polar bears starve because of melting sea ice (Leahy 2018). If all the animals kept in a captivity, all of their life requirement will be given and kept away from the threat of natural or artificial.
On the other hand, some of the general public believe that the animals are safer in wild than in zoo because of their natural habitat. For example, Polar Bears, Parrots and Elephants. Based on the various animals life needs, some of the animals like Polar Bears must stay in a low temperature as they have thick fur on their body for body temperature insulation. For the animals with big size, they cannot stay in a small captivity as it limited the event space of them. For the flying animals, they need to fly freely in the sky and not to be imprisoned in the captivity. The New Guinea highland wild dog has been unseen for more than 50 years but the scientists found out that they still survive in their natural habitat on the South Pacific Island (Petri 2017). Although animal safe in wild because of their natural habitat, however the environment of the wild is not suitable for animals to survive and might cause them dead because of predator caught or illegal hunting. Most of the animals in the wild are at continuous risk of dying for a number of reasons. There is too much matter will be faced by animals to survive in wild including physical injuries, illness, hunger, malnutrition and thirst and psychological stress. Sounds look ironic, the most threatening enemy of the animals is humans. However, the best protection could be given to the animals comes from humans too. A grizzly bear had been gunshot and dead outside the Yellowstone National Park (Bale & Actman 2016). 13 bald eagles were found out that dead on Maryland’s Easten Shore without any reason (Howard 2016).
In conclusion, the animals is safe in captivity as they can be taken care by humans and keep away from extinction because the nature wild is different from the previous wild. In my opinion, the government should emphasis the issue of environment with strengthen the legislation and also increase the number of national park to protect more wild animals from the danger.
