Zoos go by several different official names

Zoos go by several different official names. They can be called “animal parks”,”menageries” or “zoological gardens”. Despite the different names, each offers visitors the chance to view animals that are confined in an enclosure. While zoos may be fun and games for the children and the thousands of visitors that come and go everyday, is it really the best thing for the animals?
Menageries are an unsuitable environment for wild animals and should, therefore, be banned.Firstly, zoo animals are kept in a very restricted areas in comparison to their vast natural habitat.Secondly, breeding programmes are far less successful than zoos claim. Thirdly, zoo animals are exposed to many diseases and other dangers.
Animals in captivity are usually kept in very cramped enclosures (for example , Polar bears are given about ten metres of walking space whereas in their Artic home they roam for many hundreds of kilometres) with no privacy and have very few opportunities to excersise or keep their minds active, just for the sake of keeping human visitors entertained and that can affect them in many ways. Zoochosis (a condition in which animals act strangely and even hurt themselves out of boredom and frustration), stress, depression and abnormal behaviour are what most animals in zoos suffer from in their enclosures. Although zoos try to recreate the animals natural habitat by painting walls and decorating the enclosure to resemble the habitat, nothing can come close to what it actually is in the wild.
Zoos do not help animals in any way. Supporters of zoos argue that they help save endangered species, but in fact they are not very good at this.When wild animals from Africa, are brought to zoos located in India or Europe, they have to struggle to adapt to the different climates and ecosystems.
Captive breeding programmes which is the process of breeding animals outside of their natural environment in cramped conditions are what most zoos operate in order for the population of endangered animals to rise. However these programmes such as the panda-breeding programme have been very costly and unsuccessful. Also zoo life does not prepare animals taken in from the wild for the challenges of living in the wild, that is the reason why animals born into captivity, taken into captivity at a very young age or have been in captivity for a long period of time are never released back into the wild (they are instead relocated into another zoo or true sanctuaries). An example of an unsuccessful release of zoo animals are when two rare lynxes where set free in Colorado, unfortunately died from starvation eventhough the area was full of hares which are a lynx’s natural prey. This happened because the lynxes had lost the ability to hunt and fend for themselves due to the fact they had been locked up in a cage for the majority of their lives.
While zoo animals may be safe from hunters, they are still exposed to numerous dangers such as diseases and chemicals. Disease often spread between species that would never live toghether naturally. For example, many Asian elephants have died in US zoos after catching herpes from African elephants. Furthermore, zoo animals are often exposed to chemicals, solvents and other toxic substances which can be life threatening. Finally, it is common for visitors to tease and provoke caged animals.
