‘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

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
