Recommended: Effects of species extinction
Most Americans have been to a zoo or aquarium at some point in their lives. They spend the whole day outside with their friends and family looking at all the animals from all over the world. For most people, zoos are the only way they will ever be able to see these amazing animals in person. However one animal that lives in zoos across the country may not be there in a couple years.
The number of African and Asian elephants in North American zoos is declining as a result of many medical issues. A new disease has recently been discovered that is now hindering elephant’s ability to survive even further. This is a major problem because according to Science Magazine, as of 1997, there are only an estimated 291 Asian elephants and 193 African elephants left in North American zoos. Since this survey was conducted, this number has severely declined. It is now estimated that for every elephant that is born in a zoo another three die.
In the wild, female elephants are constantly pregnant or nursing. This is natural for them because their instincts tell them that they need to keep their number up in the wild or else they will be preyed on to extinction. In zoos it is much harder to accomplish this. Since there are so few elephants in North American zoos, it is hard to form breeding pairs without inbreeding. The Association of Zoos and Aquariums or AZA is an organization which is in charge of and supervises all of the zoos and aquariums in North America. Even if the elephants are just distant cousins, the Association of Zoos and Aquariums will not allow them to breed together. This is to prevent diseases and other problems from emerging. Zoos also cannot bring in new blood to breed with their elephants because new elephants are no longer ...

...imit animal suffering, but also to ensure that the human candidate has minimal risk in acquiring a zoonotic infection. Of particular concern is the possible transfer of porcine endogenous retroviruses (PERV) from swine to humans. PERV is found in the genome of all swine. It is inactive in swine but according to Wilson, there are two types capable of infecting human cells (“Viral Safety Studies”). Admittedly, in 1999, researchers found that none of the human and non-human primate test subjects that received swine tissue (or organs in some non-human primate cases) acquired PERV infection (Sharma 28). Nevertheless, PERV cannot be ruled out as a potential infectious agent since it is part of the genus gammaretrovirus, which according to the OP-ED piece “A Case of Chronic Denial”, includes several virus species that have cross-species infection implications (Johnson).
Throughout every human’s life in the United States, there will portably come a time when they take a trip to an aquarium or zoo. Do not get me wrong; it is incredible to see all those beautiful creatures up close and personal, but most people do not realize what actually is going on. Typically, when the day is spent at the zoo or aquarium, the day usually follows a schedule like this: You spend the day roaming the grounds, moving from habitat to habitat, break for lunch, and then once you’ve seen everything you want to see you return home and are free to do whatever you want to do. The harsh reality of these places is that while it is cool to spend the day there, you would never want to spend your entire life there. The animals are taken from
The physical adaptions adopted by the earliest elephants have led to the evolution of what is now recognised as the modern elephant species. The Phosphatherium, Moeritherium, Phiomia and Primelephas form the evolutionary line of the modern elephant, adapting larger physical structures, such as the skull, bones, limbs, figure and ears. Unfortunately the continuation of the elephant specie is threatened. Humans pose a great threat to the endangered elephant specie and risk the continuation and co-existence of the elephant. The evolution and continual reproduction of the elephant illustrates a significant element in society.
Zoo’s still remain as important part of any community and to the hearts of young children every year. It is estimated that more people annually visit zoos than enter all U.S. national Parks and that approximately and that 35% of people who attend zoos are adults.
The common name is the African Elephant, the scientific name is Loxodonta Africana, the phylum is Vertebrata, the class is Mammalia, the order is Proboscidea, and the family is Elephantidae. The Closest Relatives to the African Elephant are: the Asian Elephant, mammoths, primitive proboscidean (mastodons), sea cows, and hyraxes. Scientists believe that the African Elephant evolved from one of its closest relatives, the Sea Cow. The geographical location and range of the African elephant covers all of central and southern Africa. In Ethiopia there are isolated populations that exist around Lake Chad in Mali and Mauritania. Also in Kenya, Rhodesia, Tanzania, Zambia, Uganda, Zaire, and in National parks located in South Africa, as well as several other countries. African Elephants, originally, were found in all of the Sub-Saharan African habitats except desert steppes. Elephants still occupy diverse habitats such as: temperate grassland, tropical savanna and grass lands, temperate forest and rainforest, tropical rainforest, tropical scrub forest, and tropical deciduous forest despite their drastic decline in numbers. However, their migratory patterns and habitat use have changed, due to the fact that they are restricted to protected areas. The elephant can exist in many types of environments but it prefers places that have many trees and bushes, which the elephant needs both for food and shade. They also like warm areas that have plenty of rainfall.
There is but one other virus similar to the Ebola, which is a Filovirus, and that is Marburg. Ebola has a 90% death rate, whereas, Marburg is not as deadly. Their long and ropelike shape rather than roundness, as is most other viruses, characterize Filoviruses.
According to ancient Egyptian records from around 1250 B.C., animals like birds, lions, and giraffes have been kept in captivity. According to the American Zoo and Aquarium Association (AZA), a nonprofit organization that is committed to help zoos and aquariums in conservation, there are over 10,000 zoos, aquariums, and reserves worldwide. The Department of Agriculture has about 2,400 licensed zoos and aquariums in the United States alone. Of these 2,400 zoos and aquariums, only 212 are associated with the American Zoo and Aquarium Association. The American Zoo and Aquarium Association (AZA) requires that these zoos and aquariums have high quality animal care (Fravel). There is a very controversial debate on whether zoos, aquariums, and reserves

At present time Elephants have small ears to help them radiate the African heat. Elephants are in much need of water, they enjoy showering themselves by sucking water with their trunks and spraying it all over themselves because sometimes the heat can become really overwhelming, then they roll around dust to create a protective coat on their skin. Elephants today also use their trunks to eat their food. Another use their trunk for plucking leaves, but sometimes when they have to tear branches they hurt their trunk creating damage to the foliage. African Elephants eat around four hundred fifty kilograms (450) of vegetation per day. Their diet is grasses, fruit, and bark. The male African Elephant weighs around four thousand seven hundred kg to six thousand kilograms (4,700- 6,000). The female elephant weighs around two thousand a hundred sixty kg to three thousand two hundred thirty kg (2, 060- 3,030). Their scientific classification is Animalia, Chordata, Mammalia, Proboscidea, Elephantidae. The African elephant is one the largest mammals around this time, and it is an endangered species thanks to us humans for hunting
everywhere, in piano keys, jewelry, religious objects and more, but this demand caused a massive decline in the populations of African elephants. Elephants have been around for an uncountable number of years, and within the last decade poachers have killed 60% of the African Elephant population according to World Elephant Day, an organization hoping to preserve the elephant population and habitat, also state if no action is committed then the extinction of the elephant could come in the upcoming decade.
While living in the zoo the elephants are forced to live in artificial social units of two or three. In some cases they are kept alone. The elephants in captivity are deprived of the basic necessity of family and socialization. Any type of bond the animals might create is often broken, as zoos routinely shuffle elephants between facilities and other zoo’s. The effects of inadequate exercise on elephants are often deadly. Elephants are forced to live on hard
Some people may argue that zoos protect animals and species under this polluted world, however, do animals in zoos really need our “help”? Yes, but surely not that many. According to Captive Animals Protection Society (CAPS), 79% of animals in United Kingdom zoos and over 70% of elephants in European zoos are wild-caught. It seems that zoos need them rather than they need zoos.
In conclusion zoos in America are making attempts to accommodate elephants better, the local Sedgwick county zoo is planning to increase to size of the elephants enclosure. All zoos with elephants should either move them to large sanctuaries or release them back into the wild or even increase the enclosure, but no enclosure will be big enough. The cost to increase the size of orca pools would be too costly. Orcas need to be released back into the wild; the risks of keeping them captive outweigh everything else. Instead of using valuable resources on keeping elephants and orcas captive they should be focused on using the resources on protecting the wild ones and their environments.
There are two popular type of elephant African and Asian. Asian elephants are usually captured from the wild while most Asian under 25 years old ware usually captive born which means they're used to the zoo environment .(Cohn np). Zoos want to keep the endangered animal because most people are still not used to a zoo without them. Zoos should show that they are willing to do anything to keep the endangered animals they should consider creating their own sanctuaries for them. More land space in southern states away from cities, but still accessible to visitors. "Robert Wiese, formerly with the Fort Worth Zoo and now director of collections at the San Diego Zoo says, most elephants do not walk 50 miles a day" (Cohn np), sanctuary mainly offer
