Causes Of Pet Extinction Biology Essay

Abstract: This essay discusses about the sources of animal extinction. Family pets are sidestepped even as we tend to concentrate more on something that happens to our brethren. However, we also forget that what happen to our kinds, the human beings, it influences the pets and plants more, as they don't have the ability to think and change the surroundings as skilfully as we do. Habitat destruction, uncontrolled hunting and trading growing of diseases, and dramatically changing climates are among the prominent causes of creature extinction. We are exposed to what pets or animals are endangered, we are exposed to how we can conserve them, but we have yet to come in contact with what can cause the extinctions, that may rotate the ball for even more research about how to prevent them. This would be useful, as prevention is always much better than cure.

Animals are part of our ecosystem, not only they contribute to the ecosystem and help balance the ecosystem, there is also many uses in our daily lives, as the foundation of nutrition, researches, house animals and trading. But scheduled to human's greediness, selfishness and also broaden in populations, brought on the population of the animals to decrease up to the point they are in danger and eventually disappear from the surface of Earth like Dodo parrot and Tasmanian Tiger. Yet, this matter is overlooked or sidestepped as we service more of what affect us directly, whenever we should know that eventually, within the mammal types, these phenomena will also eventually us. Habitat fragmentation, damage or reduction, unsustainable hunting and animals trade, global warming and disease are the factors that lead to pet animal extinction.

Based on AZE's computation, endangered varieties under their observation contain amphibians (408), birds (217), mammals (131), and reptiles (15). This could be referred to Shape 1.


Habitat Fragmentation

One of the main factor of canine extinction is habitat fragmentation, reduction or in another phrase habitat loss. Research have been completed by Bancroft and Turchin in season 2003, using a series of experiment with grain beetles, Oryzaephilus surinamensis demonstrated that "6% out of 247 populations proceeded to go extinction" when they carried out the test on the partnership between "habitat fragmentation and lowering food plethora" and the result shown these grain beetles went to extinction credited to low food items. This result gives a advice that" habitat quality is more important than the habitat size itself". Not merely are that, another review that was completed by Warren, another researcher, who does research on 13 types of protists in 1996 by applying three levels of habitat devastation of microcosm. As the effect, the populace of the surviving species greatly declined because of the increasing in habitat damage. As we realize, Tropical Rainforest consisted of many precious trees and shrubs which used as the materials in commercial purpose. Not only for professional uses, but also as the habitat for variety of species. Due to the huge demand by various gatherings, more trees needed to be cut down to satisfy the demand of the people. As the result, that inhabitant's populace begin to decrease as there's insufficient destination to live and hunt. If this is extended, the animal's species goes extinct.

Unsustainable Hunting and Wildlife Trade

Another factor that plays a part in animal extinction is unsustainable hunting and wildlife trade. This happened in many countries around the world. Many pets or animals were hunted to extinction when the aboriginal Europeans, Us citizens and Australians developed the "effective hunting technology". One particular pets or animals were hunted to extinction by this is actually the Dodo birds. Certain bird like the Eskimo curlew gone extinct when these were "relentlessly hunted by the marketplace gunners throughout their migration". Some pets or animals were captured for pet trade such as orang utan. These pets are considered spectacular and were sold to the people that are interested in this kind of wildlife canine and were eager to cover it. "In one of the most outrageous conditions of simultaneous medicine and wildlife smuggling which occurred at Miami International airport in 1993, 312 boa constrictors that appeared from Colombia were found holding inside them 39 kilos of cocaine. All the snakes eventually passed on" Shows that wildlife not only kept as pet also for drug trading purpose. Canine such as leopards, jaguar and Guadalupe hair seal were highly favoured for his or her beautiful furs was hunted to get their pelts and the same goes to tigers where poacher killed them for their areas of the body which are used in "traditional drugs and aphrodisiacs". Not only tiger was hunted for this purpose, but rhinoceros and elephants too, were hunted for their tusks. Each one of these items were sold for high price in dark-colored market. "Commercial whaling for his or her meat and oils" experienced threatened the the majority of the Baleen whale and many toothed whales varieties in the world. Whale's meats is popular amonst the Japanese and it's really one of their favourite food, thus in order to meet up with the needs in Japan, each year whales was hunted during whaling season. Primates tend to be captured for research purpose especially in well developed country. They are simply trade to the biomedical lab with certain price which biomedical lab will use them as research in finding cure for several disease. An example of primates that often used in this field is chimpanzees. Even though they are not yet extinct, however they are classified as the endangered species because they are not only used in research but also become the aim for of the bushmeat hunter.

Global Warming

The third factor would be global warming. NATURE and its dwelling be based upon the seasons for their routines and timings. Mating season, migration, everything because of the weather. With global warming, the timing of seasons is changing. Some are much longer than expected, some are shorter than hoped. This bungled the natural clock of pets or animals that already are familiar with instinct-based timing and activities. While it seems nothing to us humans, it is consequential towards animals and plants.

Migration accelerates. ( will increase later)

Dehydration, combined with the speedily vanquishing habitats, triggers certain types to vanish. (will broaden later)

Stuart Pimm, an expert in extinctions and biodiversity at Duke College or university in Durham, NEW YORK stated that species surviving in the ecological sites tend to be more vulnerable, as they don't really have much choices of places to migrate to when the temperate changes. It is interesting to note that not as expected, the family pets living at the polar (North Pole and South Pole) is not as prone as the family pets residing in other climates, although poles have experienced seen differences. That's as a result of scarce physical places the endangered types can run to is smaller than them.

Dangerously, not only pets in endangered locations that are facing the fatalities. Relating to biologist Terry Root, of Stanford University's Center for Environmental Research and Coverage, many types are striving to hold on to their current locations.


There are two groups of diseases: natural incident, which is produced since a long time and unpreventable, and the other one would be human-induced or mutated. Both would give dire outcomes on the types affected, especially in public.

Among the exemplory case of human-induced diseases are ramifications of insecticides. Insecticides are seen as a low-level dangerous compound, as they tend to prevent high plants reduction. However, it also pressured pests and infections to develop. Once evolve, we'd need a higher dose of insecticides. In the long run, the consequences of insecticides in plants will have an effect on the pets or animals that eat them too.

Besides that, there are effects that happen not to the animal directly, but towards another era. A hen may lay eggs with thinner and fragile eggshells. This, while appear trivial, could actually result in a higher threat of survival. Over time, extinction would not be far in the foreseeable future of the kinds. This really does happen. One insecticide, DDT, induced the eagle and peregrine to create eggs with delicate eggshells, creating the eggs to break when the mom sit on them. How can they be incubated without the mom warming the eggs? How do the mom incubate the eggs without seated in it, yet when it rests, they will break? These are one of the complexities that we don't understand or didn't placed into the equation when we create the insecticide.

Too much security would also be harmful. When a species is covered from hazards and diseases up to paranoid level, it causes them to have lower and lower immunity with their offspring. This causes those to be vulnerable and unable to sustain injury and total fatalities if they ever get any attacks.

Lastly under the factor of diseases, will be the effects of genetic evolution. Although it was not the total annihilation of types, it continues to be, in a sense, the cause of species extinction, happening because of the chances of success with the increased or reduced potential. Perhaps a smaller or strong body is better adapting during this time period of the time, whereas velocity and agility is more vital during the past. This theory applies to the birds, where during prehistoric times; birds have wider scales of bone fragments while they have smaller lighter body now. Habitat, food consumption, and brain metabolism, all add towards genetic advancement, triggers the extinction of the more mature type of kinds in exchange for an improved, new kinds.


Thus, it is supported that the evidently seen triggers are habitat reduction, unsustainable hunting and trading of wildlife, global warming, and finally, infectious diseases. Two of it where we contributed a great deal in so that it is much worse, and two of the last mentioned in which we have considered part albeit indirectly.

Although just a little out-dated, this research still maintain a lot of truth. It really is hard to invest in more of the kind of research, once we humans will be more interested in studying further of things that brings more material benefits rather than invisible threats. Were keener on studying on the psychology of prospects, convenient products, and less intake of resources. These studies are conducted with good intentions, but obsession of any narrow subject makes us adding a blind eyeball over other activities that matter too, specifically, other creatures co-existing with us. A number of the recommendations here were spoken on 2006. Now, it's 2011. In the period of 5 years, how much have we lose, can you imagine?
