155 Words Essay on Endangered Animals for school students
Some fear that turning the spotlight on small species will weaken the attraction of zoos. Zoos need to balance conservation credibility with commercial viability; to reach the aim of species conservation they need to attract visitors. The focus on charismatic mammals is considered to be appropriate because these animals are supposed to act as flagship species or ambassadors that raise public awareness and support for in situ conservation (Baker , 147; Leader-Williams et al. , 237). However, the assumption that zoos will not attract enough visitors without large mega-vertebrates is far from uncontroversial. Recent findings even suggest that small mammal displays yield a higher cost to benefit ratio, in terms of exhibit popularity per unit cost, than large mammal displays. They also suggest that imaginative displays of small-bodied species can substantially increase zoo attendance (Fa et al. , 79).

Most animal rights proponents will resist any attempts at such value balancing. They consider infringing an individual’s right to freedom for the sake of the preservation of the species as morally wrong. For Regan any type of captivity or manipulation of a sentient animal is morally unacceptable, irrespective of the possibly beneficial consequences for the protection of rare or endangered species. The rights view’s answer to the question whether zoos are morally defensible, “not surprisingly, is No, they are not” (Regan , 46).
The climate change endangers the species, so much so that the animals have become one of the icons that conservationists use to illustrate the threat posed by climate change (The Huffington Post, 2014)....

However, not only are the success rates of breeding programs disappointing, the prospects of reintroduction programs are also low, largely because ecological, social, economic and political aspects were not taken into consideration. Reintroduction is a costly business which often diverts attention from other, more cost-effective options. In captivity, animals risk losing the skills they need to survive in the wild. Lastly, the ecosystems into which they are eventually released are dynamic systems which have often undergone dramatic changes in the time span between the breeding program and the reintroduction, sometimes as a result of anthropogenic disturbances such as CO2 emissions and deforestation. A review by Beck () estimated that only 16 out of 145 reintroduction projects using captive-born animals were successful. It also showed that most animals for reintroduction do not come from zoos but from other specialized facilities. Although the situation improved after the development of the Guidelines for the Placement of Confiscated Animals (IUCN ), the performance of zoos regarding the reintroduction of captive-bred animals still fell far short of expectations. Instead of a guiding light, reintroduction proved to be a shooting star, “providing an eye-catching attraction but not long-term illumination for conservation” (Price and Fa , 173).

By the turn of the century, Noah’s Ark seemed to have become irretrievably shipwrecked as the zoo community started to realize the limitations of ex situ (zoo-based) conservation as a prelude to in situ (field-based) conservation (Lees and Wilcken ). The vision of the zoo as a Noah’s Ark has gradually given way to a new paradigm, the ‘integrated approach’. This transition becomes apparent when the first World Zoo Conservation Strategy of 1993 is compared to the new World Zoo and Aquarium Conservation Strategy of 2005. The first document explicitly describes reintroduction as the ultimate goal of ex situ conservation. The second document, on the other hand, recognizes the reintroduction of captive-bred animals as a useful instrument for the conservation of wildlife, but cautions against high expectations because of the complexities of returning these animals to the wild (Price and Fa , 156). It outlines a much broader conservationist role for zoos, including research, training, education, awareness campaigns and direct support for in situ projects. In the latest strategy, the primary mission of zoos is to integrate all these elements with their efforts to protect endangered species and conserve healthy ecosystems (Mace et al. ; Bowkett ; Lees and Wilcken ). Insofar as captive-breeding for reintroduction is considered necessary and appropriate, it should be accomplished as part of such a larger, integrated, holistic program (Hutchins , 18).

Research has shown that zoos currently hold roughly one in seven (15 %) threatened species of terrestrial vertebrates (Conde et al. ). Moreover, zoos even struggle to breed these few species because the populations are usually too small. As Sarah Long, director of the Population Management Center in Chicago, has remarked, “Noah got it all wrong. One or two or even a dozen of each species is not enough” (Kaufman ). Initially, the target of zoo breeding programs was to maintain 90 % of genetic variability of a species for a period of 200 years (Soulé et al. ). Because this time frame requires very large numbers of animals per species, it has been reduced from 200 to 100 years in the mid-1990s. But the majority of breeding programs do not have sufficient space to meet even this objective.
