Ah, the great zoo debate. The existence of zoos and the animals held within them has divided animal lovers and pulled on the heartstrings of conservationists and activists alike. On one side of the spectrum lies the belief that the animals are best viewed where they should be – in their natural habitats. The other side of the debate pleads the case that zoos are actually helping to save some species from extinction, while simultaneously increasing the life expectancy of the animals there. And the numbers certainly do not lie.
Based on a study done by the University of Zurich and the University of Lyon (we find their name very fitting), it was found that 80% of all mammals in the study lived longer in captivity than their wild cousins. The zoological databases included over 50 different mammal species. So, those were the results of the study. But, you probably want to hear why some of these animals are living longer in their zoo homes.
1. No competition, no problem
Sometimes, a large population can be overwhelming for an ecosystem. Individuals within a species have to compete for resources like water, food, and habitat space in order to survive. Those in zoos have virtually no rivalry.
2. Pollution is absent
Human interference places a large burden on wild animals. Luckily, their habitats are well-protected within the zoo’s enclosures.
3. Frequent vet visits
An apple a day does not keep the veterinarian away, because zoo animals are under constant monitoring for disease. Any sign of sickness is reported and treated immediately so the animal has the best chance of survival.
4. Reliable research and higher husbandry
Scientists have devoted countless hours to studying animal behavior, health, nutrition, and general biology in order to provide the best data on caring for captive animals. That way, taking care of them can mimic their exact natural environment. Their every need is taken care of.
The situation is this: Some larger and more complex species do not have extended lifespans in captivity. But they are a rare exception. Assuming, of course, that each zoo takes the time to ensure proper care of each animal, most captive species have a better chance of survival inside the park. Thank you, zoos!
