Animals that live under human care are in captivity. Captivity can be used as a generalizing term to describe the keeping of either wild animals or domesticated animals such as livestock and pets. This may include for example farms, private and zoos. Keeping animals in human captivity and under human care can thus be distinguished between three primary categories according to the particular motives, objectives and conditions. The domestication of animals is the oldest documented instance of keeping animals in captivity. This process eventually resulted in habituation of wild animal species to survive in the company of, or by the labor of, human beings. Domesticated species are those whose behaviour, life cycle, or physiology has been altered as a result of their breeding and living conditions under human control for multiple generations. Throughout history not only domestic animals as pets and livestock were kept in captivity and under human care, but also wild animals. Some were failed domestication attempts. Also, in past times, primarily the wealthy, aristocrats and kings collected wild animals for various reasons. Contrary to domestication, the ferociousness and natural behaviour of the wild animals were preserved and exhibited. Today's zoos claim other reasons for keeping animals under human care: conservation, education and science. Should Animals be Released Back into the Wild or Kept in Captivity?
Let us weigh the pros and cons of this issue, which seems to be on the rise.
2. THE ADVANTAGES OF ANIMALS IN CAPTIVITY
The advantage of animals in captivity is protecting the endangered wild animals, sometimes a species may have difficulties in surviving in the wild. Such as adapt helped a certain species of Dart Frog survives, when its habitat was destroyed by natural disaster. To prevent and preserve wild animals, from being captured by poachers for their skins, ivory and supposed medicinal purposes, zoos seem to be a safe
