Phobias can be acquired through classical conditioning by pairing a neutral stimulus with something that causes grave pain (NIU‚ 2003). Phobia reactions can be ongoing unless the individual is exposed to the extinction process. According to NIU (2003)‚ during the extinction process‚ an individual must face the fear without the presence of the unconditioned stimulus. For example‚ in the experiment conducted by Watson and Rayner‚ Little Albert formed a phobia of white rats and other furry

Endangered species are those considered to be at risk of extinction‚ meaning that there are so few left of their kind that they could disappear from the planet altogether. Endangered species are threatened by factors such as habitat loss‚ hunting‚ disease and climate change‚ and usually‚ endangered species‚ have a declining population or a very limited range. The current rate of extinction is thought to be far greater than the expected natural rate‚ with many species going extinct before they have

Humans’ Moral Obligation to Preserve Endangered Species Many species that exists today are becoming endangered to extinction. In the past era where humans did not exist‚ extinction occurred due to natural causes. On this present time however‚ extinction of species are threatened by humans’ existence. Humans are the only moral agent; in which‚ it has the intellectual capacity that animals and plants do not have. Thus‚ humans are powerful and dominate over any species. Many practices that humans

‘overkill’ theory persuades readers of the responsibility of prehistoric human civilizations in the mass extinctions of megafauna during the late Quaternary period. Nevertheless‚ inaccurate comparisons of continental and island species along side impractical and idealistic evaluations of human predation renders Martin’s theory into the realm of ambiguity. In specific‚ Martin alludes to the extinction of flightless birds and land snails caused by the spread of humanity to islands of the remote Pacific

down a lion became easily available to anybody who wishes to have one. But along with these advancements in weaponry came the realization of what had happened. Many species had been hunted to the point of extinction; there was no bringing them back. So‚ laws began appearing to prevent the extinction of other endangered species. Unfortunately‚ these laws had little effect. Furthermore‚ man is not the only predator within the animal kingdom. As a result‚ enclosures were built with the intent of protecting

In my opinion passing the Endangered Species Act of 1973 (ESA) was necessary to protect the extinction of wildlife. Scientists have proven that one extinction can cause a disruption in the food chain‚ which has a domino effect on other extinctions. These extinctions can cause harm to humans. In all the environment is related to humans‚ if we like it or not. My belief is that implementation this act has not only helped with the preservation of wildlife and ecosystems‚ but also has benefits on humans

For millions of years‚ extinction among animals was а natural process. In fact‚ it was part of the process of evolution. In recent years‚ however‚ the extinction of some species has been the result of human activities. Had it not been for these‚ many more animals would have survived. Some species have either been made extinct‚ or become

and animals may be very close to extinction. North America experienced a big loss of megafauna at the end of the Pleistocene era (about 13 000 years ago). This started a program known as “Pleistocene re-wilding”. Re-wilding involves the reintroduction of extant species into areas where they became extinct in the past. This program aims to restore the evolutionary and ecological potential that North America lost all those ago‚ and in the process‚ prevent the extinction of the megafauna in Africa and
