Koalas crises
Have you ever seen koalas except zoo? Mostly, people can see koalas in Australia. In “History of Koalas,” from the website “Australian Koala Foundation,” says, “ Koalas or koala-like animals probably first evolved on the Australian continent during the period when Australia began to drift slowly northward, gradually separating from the Antarctic land mass some 45 million years ago. Fossil remains of koala-like animals have been found dating back to 25 million years ago ”(1994, para.1). In Australia, there are many species but they are also endangered species. Koalas also one of the endangered species in Australia. These days, people focus on environment on the earth so they try to save endangered species from any factors of death. In addition, koalas are actually very easy to feel stress. For example, when you hug koalas, they feel stress. Moreover, when they got too much stress, they would get deadly disease. Those stressors are very familiar with human activities. At first time, veterinarians who are interested in koala examined the causes why so many koalas died in recently. At that time, people thought the cause of koalas died was Chlamydia, which is one of the worst diseases. However, after examined the cause, researchers found the truth of koalas died. Actually, the causes of koalas died were not only Chlamydia but also bad effects of stressor. In addition, koalas are suffered from the destruction of their habitats, diseases, drought, forest fire, car crash, and attacks from pets. The International Union for Conservation of Nature has finally decided what koala is the endangered species since 2000. In addition, the government in Queensland in Australia decided what koala is one of the endangered animals in 2003. Obviously, the reason why they are becoming one of the endangered species are because of human beings. As you notice, people, government, and their law must protect koalas from many accidents.
The first major reason of decreasing koalas is destruction of koalas' habitats. There are a lot of farms, houses, and factories in Australia. In addition, these are trying to expand more or build more even though koalas do not have any forests to live in anymore. In “Interesting facts about koalas ” the author states, “Each koala’s ‘home’ is made up of several trees called HOME TREES. They visit these same trees regularly. The area covered by these trees is called the koala’s HOME RANGE. Each koala has its own home range, which overlaps those of other koalas but except for breeding purposes, they do normally not visit another koala’s home trees. The size of each home range depends upon a range of factors including the quality of the habitat and the sex, age and social position in the population of the koala”(1994, para.6). Thus, decreasing forests for koalas living in, many koalas may live together in same forests because of decreasing their habitats. It occurs many fighting for their territory, and lacking food and trees for sleeping. In addition, if the forest that many koalas live in were to catch on fire, these koalas would lose their place to live. The most serious matter is those problems make koalas feel too much stress. Too much stress makes koalas be easy to get disease, get sick and die.
The second reason to according koalas die is a sort of lacking education about koalas. Koalas are suffered from car crash and pets' attacks. In “Threats to the Koala ” the author says, “When habitat is cleared for roads, and housing estates, cars and dogs become a serious threat to koalas. Over 4000 koalas are killed each year by cars and dogs” (1994, para.4). Actually, koalas are one of the noctual animals so, they move actively at nighttime. Therefore, car drivers need to drive carefully and slowly at nighttime. In addition, the pet's owners should know koalas’ behaviors. In “Dogs, cats and owners’ rights.” The author states, “ Dogs have all day to play, and tend to do most of their exercise when you take them for a walk. At night, when koalas and other nocturnal wildlife are most active, your dog is better off close by your side. By restraining dogs at night, many attacks can be avoided” (1994, para.16). The author of “Dogs, cats and owners’ rights.” also says, “Most dogs feel threatened by the sight of a koala in their yard and will naturally attack to protect their territory” (1994, para.14). Most of people do not know what koalas are nocturnal animal, so it occurs those accidents. To protect koalas, people should get knowledge for koalas. Moreover, the government also should let people notice koalas' behaviors.
Third, people have to let koalas avoid any diseases. People cut trees and destroy koalas’ habitats. Moreover, they build factories, farms, and houses where they destroyed koalas’ habitats. Besides, they pollute around those areas with scraps, polluted water, or dirty things. Those things are causing of koalas’ disease. As you know, koalas have a deadly disease, which is Chlamydia. In “Threats to the Koala” the author states, “There are 4 common koala diseases caused by the chlamydia organism: conjunctivitis which can cause blindness, pneumonia, urinary tract infections and reproductive tract infections, which can cause female infertility. The symptoms of chlamydia manifest as sore eyes, chest infections, and "wet bottom" or "dirty tail.” Chlamydia is harmless in populations with unlimited resources, but manifests in times of stress, which happens when habitat is reduced. In disease-free populations which have been moved to areas where they were not native or where there is not enough habitat to support them (such as on some islands off Victoria and Kangaroo Island in South Australia), problems with overpopulation have arisen because of this unnatural situation” (1994, para.4). The causes that koalas get disease are not only pollution but stress is also cause of getting disease. At first, people have to make effort to take koalas away from any stressors. For example, people should try to live separate from wild animals’ living areas. Moreover, people should better to plant trees to expand koalas’ habitats. It would solve the fighting of koalas’ territory.
Last, the government of Australia should put a strong law to protect koalas. Some part of Australia enforced the law to protect the endangered species. However, other part of Australia don't enforce yet. In addition, those laws to protect koalas are not enough effective. For example, there is a law to protect only koalas. However, that law doesn't protect the koalas habitats. Thus, people could make roads into the forests, and live in the forests very easily. Those problems occur the car crash, and pets' attacks. However, according to the author of“TheAUSTRALIANKOALAFOUNDATION”(2004), “The National Koala Act is a law that theAustralian Koala Foundation would like to see enacted to provide greater protection to thespecies. This new law would aim to protectkoalas and their habitat by: focusing on the protection of koala habitat, not just koalas; provide incentives and participation bylandowners to protect koala habitat; make a significant contribution to a nationalkoala recovery program, and set a precedent for other species - specificlegislation”(p. 5). If those law would spread out whole part of Australia, the endangered species might be well protected. Therefore, the government should put a strong law for protecting koalas immediately.
In conclusion, most of reasons that koalas died are because of human activites. And those activites are effecting koalas to get too much stress. Thus, those stress occur koalas to get deadly diseases and die. First of all, people need to make effort to take koalas away from stress. The most important things are not only taking care of endngered species also making good relationship between human beings and endngered species such as considerating species and releasing from fear of human activites. Therefore, for koalas, people shoud make effort to save them all the time.
