There has long been an argument against maintaining zoos in which animals are kept away from their natural habitat, and there is strong evidence to suggest that technology has developed to a point where such institutions are no longer needed, as will now be argued.
Traditionally, the principal argument voiced by those who wish to retain zoos was that it allowed children and adults to see animals which they more than likely would not have had a chance to do if this had required visiting the creature's natural environment. Yet there are now online videos and websites where these animals can be seen in high definition, therefore no longer needing to go to enclosures to see the animals. This is clearly evident by the declining number of visitors in recent years.
In addition, there are many cases in which animals held in captivity are not well cared for and are used solely to exploit them for profit. In some rare cases, the animals can suffer from neglect or malnutrition, and rather than being kept healthy are simply replaced when they are no longer of any value. Granted, there are situations in which endangered species are protected and their numbers allowed to rebuild by housing them in the security of a zoo. However, in most cases the same effect is better achieved by using more open plan wildlife parks rather than traditional caged enclosures.
In sum, the factors which first led to the creation of zoos have been reduced by the ability of technology, so unless there is some advantage for the species itself, then the use of zoos should no longer be supported.
