Extinction Of Species Essay

Species revival does come with beneficial factors, giving reasons for why it is possible. However, with various types of research, there are causes that result in debate and hesitance to furthering development of the idea. This is very common in the debate of pursuing de-extinction for different points. First, a major question returns of “ where do we put them—what changed in their original habitat that may have contributed to their extinction in the first place?” (Text 3 Lines 25-27) There were

rulers, yet both of these seemingly unstoppable species fell to an even greater power: extinction. Now humans reside at the top, but as another extinction threatens earth’s ecosystem, humans and billions of other plants and animals may perish similarly to the many species before them. Alexander Pyron explores the degree to which humans should preserve biodiversity and endangered species in his article “We don’t need to save endangered species. Extinction is part of evolution.” Pyron writes to convince

Scientists believe, that the earth in the middle of a sixth ongoing mass extinction, which was given the name of The Holocene extinction due to our modern Holocene epoch. Discussion The Holocene epoch continues from 11 500 years ago until the nowadays and still keep going. Sixth Extinction event can be blamed for significant loss of larger mammals (woolly mammoth, cave lion, cave bear and etc.) during the end of Ice Age extinction event 9 000 to 13 000 years ago, which was caused by climate change.

Five mass extinctions have occurred throughout the history of planet Earth. It is predicted by Author Elizabeth Kolbert, that a sixth extinction may be underway. The Sixth Extinction is a book in the viewpoint of Kolbert and narrates her travels around the globe while she studies numerous wildlife species. Kolbert claims that ¨Those of us alive today not only are witnessing one of the rarest events in life's history, we are also causing it,” (Kolbert, Page 8). Throughout her work, Kolbert claims

events in climate changes are the mass extinctions that they associated with. Currently we are undergoing the sixth great mass extinction event in our planet's history. While several of these events were due to volcano activity or asteroid strikes, others were due a change in Earth's climate. It is estimated that the Earth is losing species to extinction at 1,000 to 10,000 times the natural rate (The Extinction Crisis, n.d). The primary driver for this extinction event are humans. Several factors are

the Mammoths: Ice Age Extinctions and the Rewilding of America, University of California Press, 2005, Prologue and Chapter 2 Summary The overkill hypothesis stresses the fact that people were the main technicians behind the late pleistocene extinction of fauna in Northern Eurasia and North and South America. Paul Martin of the University of Arizona and others see a subsequent and spontaneous connection between the presence of people and the vanishing of numerous species of large mammals. According

safeguading of endangered species is unnatural and poses many drawbacks and provides three reasons of support. However, the professor explains that the extinction of the species should be prevented whenever possible because it has a bad consequence to the environment and refutes each of the authors' reasons. First, the reading states that the extinction of the dinosaur did not result in lasting harm to life on earth. The professor opposes this point by saying that after the extinction of the dinosaur, a

kangaroo. They were marsupials but behaved more like wolves than marsupials (which makes them an excellent example of convergent evolution). They became extinct in Australia and New Guinea because of their incompetence against the dingoes, an invasive species brought by the aboriginal men. Nevertheless, some were left in Tasmania as the dingoes did not reach there, but died out soon after Europeans arrived there. Similar story includes the dodo’s tale which is illustrated perfectly by Richard Dawkins in

“paleontologists characterize mass extinctions as times when Earth loses more than three-quarters of its species in geologically short interval…” (Barnosky). Since the life on Earth came to existence it has gone through multiple mass extinctions, five to be exact. Throughout these extinctions, there has been the loss of millions of species that will never come back into existence. When the term mass extinction is heard the first thought that most come to mind would be the extinction of dinosaurs, and how it

megafaunal mass extinction took place. It’s still debated whether humans are to blame for this, since this megafaunal extinction happened after the arrival of humans or if climate change is entirely to blame. Fossil evidence has been of great help in finding what factors might’ve caused this extinction. This mass extinction that took place is related to the Anthropocene because if humans were the main cause, humans need to be more careful now because their actions may lead to more extinctions. The observations
