Let's examine what affects zoos have on humans and non-human animals:

Despite their professed concern for animals, zoos remain more "collections" of interesting "items" than actual havens or simulated habitats. Zoos teach people that it is acceptable to keep animals in captivity, bored, cramped, lonely, and far from their natural homes.

Animals in zoos are treated like stamp collections. The more animals the better, especially if they are large animals from foreign places that the public would be willing to pay money to see. It doesn’t matter if a zoo have only one of a species on its own, or if the space is much too small for the animal. The "specimens" are arranged in cages to make it easy to observe them at close range and at all times. They are captured from the wild, and many die during capture and transport.

The power and dignity of these animals are often stripped from them and instead of being at one with an environment for which they have evolved, they sit in a wasteland. They are often no more than caricatures of their wild counterparts.

Caged animals are deprived of their normal society, their families and mates. They have little opportunity to run, soar in the sky, swing through the trees, or roam over large distances. Most importantly, they usually have nothing to do, and don't need to use their intelligence and skills to solve daily problems of survival. they go mad from boredom. Nothing much changes in a zoo enclosure.

Space in zoos rarely, if ever, matches the animals' natural range, and more commonly is reduced instead to virtually nothing. Animals which would naturally roam for tens of miles a day tread the same few paces daily. Some of the fastest animals on earth live in pens so small that they could not gather pace to a trot, let alone full speed.
Giraffes, which drift gracefully above the trees in Africa, in the zoo, become awkward looking freaks in a sideshow.
Some zoo enclosures mean that the inmates cannot even enjoy their most basic behavioral repertoire including exercise, social interaction and bathing.
Birds are virtually stripped of their most precious gift - flight, often able to do little more than flutter their wings. Birds of prey do not soar, but perch and vegetate. Consequently, captive birds like vultures and pelicans are prone to bone disease. For fifteen hours a day, many animals may be shut away in their night quarters with even less room to move. However, it is not just a matter of space, but also the quality of the environment.

Chimpanzees are our closest relatives in the animal kingdom, their intelligence is universally accepted, but they exchange the infinite possibilities of the forest for little more than playground climbing frames, which would not keep a human child occupied for hours, let alone years.
Creatures of the night cannot spend a day away from prying eyes. Reptiles may climb or scratch at their glass tanks because they don't understand why they can't get out.

Birds' wings may be clipped so they cannot fly, aquatic animals often have little water, and the many animals that naturally live in large herds or family groups are often kept alone or, at most, in pairs. Natural hunting and mating behaviors are virtually eliminated by regulated feeding and breeding regimens. The animals are closely confined, lack privacy, solitary and shy animals are often in enclosures with viewing from all sides, have little opportunity for mental stimulation or physical exercise, resulting in abnormal and self-destructive behavior, called Zoochosis.

Deep instincts that have evolved over thousands of years can't find any outlet. The result is boredom and stress. Animals may become apathetic and just sit in one place. They may show signs of mental disturbance through abnormal behaviours.
Such obsessive and repetitive behaviours (known as stereotypic behaviour), including self-mutilation, are common amongst other zoo animals as a result of frustration and boredom. Such pointless repetitive movements have also been noted in mentally ill people.
With nothing to do, these zoo animals go out of their minds.

The most common abnormal behaviour was repeated movement: rocking from side to side, pacing up and down or round and round, waving or circling the head, over and over again. Many species showed such behaviour in captivity. The physical, mental, and social aspects of the life of a wild elephant are so complex. Wild elephants frequently bathe in mud and water. This maintains the skin and is a pleasurable experience enjoyed by whole families of elephants. Elephants also dust themselves with dry earth, which it is believed protects the elephants from the sun and insect bites. For elephants in captivity, particularly in circuses, these behaviours are not possible. Elephants are also deprived of basics such as mud wallows and dusting facilities. An elephant whose herd and social structure are so important, imprisoned alone. Elephants spend 22 percent of their time engaging in abnormal behaviors, such as repeated head bobbing or biting cage bars.

Polar bears often suffer severe mentally disturbance. They spend about third of their time pacing a sign of distress bears pulling out their own fur to the point that the belly and hind legs are bald. The death rate of cubs in captivity is twice as high as in the wild.
Caged big cats will often pace the same path again and again, their plodding step not faltering, crushing vegetation to leave a neat track showing the course they will walk for the rest of their lives. Great apes and elephants will rock, sway or shift repeatedly from side to side. Other disturbed behaviour, particularly amongst giraffes, may include licking the walls and chewing the bars of their pens. Jaguars chew the end of their tail, which has become completely bald. Primates may over groom themselves or each other and this can lead to self-mutilation. Disturbed maternal behaviour may also involve over grooming but also the rejection or killing of young. Abnormal behaviour in reptiles may manifest itself as climbing or scratching at their glass tanks because they don't understand why they can't get out. Other reptiles may become completely sedentary, seemingly sleeping their lives away behind a rock. The animal may be trying to wait out the environment in which he/she is trapped, but the wait never ends.
Gorilla smearing faeces on walls and eat them. Gorillas and a chimpanzees vomiting and eating their vomit.

This repetitive, apparently senseless behaviour indicates neurosis or even insanity. It is caused by boredom, loneliness, frustration, stress and psychological and habitat deprivation.
It is humans who pay for this. They pay to other humans who cause this. And it is humans that profit on the account of the nonhumans sanity. So who really is the insane?

Zoo babies are great crowd-pleasers, but what happens when babies grow up?
Zoos often sell or kill animals that no longer attract visitors. Deer, tigers, lions, and other animals that breed often are sometimes sold to "game" farms where hunters pay for the "privilege" of killing them; some are killed for their meat and/or hides. Other "surplus" animals may be sold to smaller, more poorly run zoos or to laboratories for experiments.

Zoos also claim to be educational. But what can they teach us when they can't see how wrong it is to cage and pen wild animals? Animals, which have become depressed or show unnatural stereotypic behaviour are only 'educational' in showing how man can drive an animal mad by keeping it in unnatural prison-like conditions.

Ultimately zoos and safari parks are simply entertainment. Some even present animals performing little more than circus tricks to keep the visitors amused. People who go to zoos go simply to amuse themselves, and not to actually learn something about the wonderful creatures who share this planet with us.

Zoos claim that they afford people the opportunity to see something that many will never see in the wild. This is true. The zoo world is one where the primates hide their faces, the predators never hunt and mothers eat their young rather than let them survive. Elephant will rock and swing for hours. Bears, dogs and cats pace; monkeys stare; rhinos circle.
Anthropoid apes will eat faeces and gorillas their own vomit. The zoo people are right, you won't see these "things" in the wild.

Zoos emphasise the domination of humans over other species. This confinement suggests that humans can do as they wish with other animals. Zoos teach us a false sense of our place in the natural order. The means of confinement mark a difference between humans and animals. They are there for our pleasure, to be used for our purposes.
Innocents-in prison all their life. Lonely, solitary beasts shuffle around concrete enclosures, their eyes sad and empty.

Conventional campaigns will only wider the cages not liberate the animals.

We are their only hope.
