Keeping animals in captivity has been practised since very long. Putting wild creatures in cages is neither a good thing. In my opinion, captivating animals is not always a cruel deed in most cases where it proves to be an advantage to both humans and the creatures that were living before I the wilderness enjoying utmost freedom.
Firstly, the keeping and breeding of vulnerable animals in zoos and circuses ensure their protection better. The era has changed; today’s world is that of factories, houses, hotels, restaurants not a world where the wildlife may have enough space to survive. For this reason, with the help of many organizations as the World Wide Fund for Nature have built zoos where these animals can be kept and be bred in security.
Endangered natural life can also be saved by keeping some of the species in cages. In Mauritius, for example, the kestrel – a unique bird – which was in great danger of extinction is now present in big numbers throughout the island. It is true also for the Mauritius Parakeet and the American Bison and the trumpeter or swan both of North America as well as for other worldwide animals. In captivity, protected from any danger, the endangered animal species are observed by scientists who then set up the creatures’ surroundings almost as it was in nature. Thus, in their respective environment, the caged creatures adapt themselves: the male and female then reproduce, increasing the population. This method, therefore, is not cruel but a successful means of saving endangered species from becoming extinct.
In certain cases, some animals become too dangerous to let them roam about freely. Tigers, leopards and other carnivorous creatures at times break into farms and kill the cattle, an easy prey due to the lack of food. There, they are often shot by the angry farmers. Some of the fierce hunters die while others become man-eaters – a definite threat for human life.
