There are billions of animals in captivity around the world. These animals are found in zoos, breeding centers and research laboratories. All of these animals are lashed due to the stress of being in a small confined habitat. Is it ethical to keep animals in captivity for research, breeding or for our entertainment? Over the years, keeping animals in captivity has not changed the safety and welfare of the animals. The reasons why animals are kept in captivity might favor some people and not others. Animals in captivity are usually kept for entertainment, education, research and conservation purposes. The other main reason they are held captive is the rehabilitation process. The article, Ethical Issues, defines rehabilitation as the treatment of wild animals found injured or ill, held in captivity until they are back to full health, and then released back into the wild. Then, when the animal is released, it can live freely in its habitat. Although this can lead to suffering and stress or even death for the animal. The animal is so dependent on its keeper that once released into the wild it behaves badly (1). In The Art of the Cage, a saying is mentioned "to find enrichment is sometimes to have no enrichment at all". This results in the fact that a captive animal may not be fed for a period of several days. By keeping animals in cages and separating them from their mate, parent, or offspring, you prepare them for the wild. In nature the animal needs to endure the difficulties it may encounter. As the animal faces these difficulties, it gives them resistance, self-sufficiency and survival instinct. In the past people collected animals had a way to express themselves with the gods to be closer. The zoo shows the symbol o... in the center of the card... also danger. A good reason for captivity is the rehabilitation of an injured or injured animal that could be treated. So have a second chance to return to freedom. Even preventing endangered species from becoming completely instinctive by discovering an animal's genetics. So having zoos and farms helps animals but puts them at risk. Works Cited1.
