Mass Reflection

The reading by Paul S. Martin, Twilight of the Mammoths: Ice Age Extinctions and the Rewilding of America, explores the idea that extinction is a phenomenon that could be explained by human arrival. Humankind has an impact on animal extinction. He says: “based on the concept that animal populations could have sustained some additional predation, but not as much as took place after human arrival, this explanation has come to be known as overkill “(Martin, 48). In this passage Martin is explaining that humans are predators and upon their arrival many animals died. Martin also goes on to say that meteor strikes and climatic

While implementing Primary Health Care models, identical to those in metropolitan areas, in a rural setting is not practical, I feel there is an obvious need to improve primary health care in remote areas. This is due to the significant health gap between Indigenous and non-Indigenous Australians, in rural and remote areas

There have been five major mass extinction on earth triggered by a distinguishable event, but in The Sixth Extinction: An Unnatural History, Elizabeth Kolbert writes of the narrative of the sixth extinction caused directly by human impact. The book identifies the effects of human activity on how, over humans history on earth, the natural world has been affected. Every environmental impact stems into three basic groups of global problems to nature: Pollution, Habitat loss and Invasive Species. Kolbert explains that each impact can be traced back to one source, human industrial development. With each impact various types of life in the natural world are affected. Deforestation, urbanization, and sea level rise contribute to habitat loss worldwide. When humans began to travel they also brought invasive species and disease along with them; as boats only became bigger more and more invasive species travel. This reverse engineering of the planet species, brings new species that don’t have any natural predators, thus having an easier time driving native species out to endangerment or extinction. The different outcomes that come from human pollution is separated throughout the book, but the idea remains constant; with the development of human culture, pollution has drastically impacted a vast extent of species habitats and their environment.

American journalist Elizabeth Kolbert authored The Sixth Extinction: An Unnatural History in 2014. This is a non-fictional account of what Kolbert had named "the sixth extinction": an extinction event caused by humans similar to ones that destroyed earlier forms of life, like the dinosaurs and megafauna.

List examples of human activities that are suggested to be key triggers for the sixth mass extinction.

The scientific community applauds Elizabeth Kolbert for her recently published The Sixth Extinction: An Unnatural History, as it exceeds scientific and literary standards. Elizabeth Kolbert, born in 1961, is a American journalist and author and has won more than ten awards since 2005. In fact, The Sixth Extinction: An Unnatural History recently won her the Pulitzer prize for general nonfiction writing. For a scientific overview of her book, it discusses quite exactly what the title states. There have been five mass extinctions throughout the history of this earth, and the sixth is currently happening and being driven by humans. Kolbert discusses several different species that have become extinct or are on the brink of extinction. She includes history of mankind discovering the concept of extinction as they gradually began to wrap their brains around the idea in the early eighteen hundreds. Lastly, Kolbert masterfully describes her own experiences face to face. She

There have been many scientific studies conducted to prove and disprove the many theories. However, scientific evidence indicates that both gradual climate changes and sudden catastrophic events have caused past extinctions. The question now is if the sixth extinction will be the result of a sudden catastrophe or a more gradual event caused by humans. The effects that humans are having on the earth is often the subject of debate among scientists and ecologists. Data exists that proves human innovation and expansion has contributed to decreased air and water quality as well as global

This semester I learned a lot about writing in English 151. It has been a roller coaster ride with these essays for me this semester. I learned step by step how to write a good essay and how to have your readers be engaged in what you’re trying to tell them. Each essay I did has taught me something valuable I can take to the next level of English. I feel as if as the semester went by I did not take my writing that seriously and that reflected in my grades I received in each essay. It made me a better student and writer and it will reflect next semester. In this essay, I will reflect on what I learned throughout this semester that you should apply in your writing when you begin English 151.

The sixth mass extinction is on the way and could be as massive as the extinction that wiped out the dinosaurs (Kolbert, 2014). Before learning more about the sixth mass extinction, you’ll have to first understand what biodiversity is and what will happen when you tamper with it. According to Anup Shah, author of Why is Biodiversity Important? Who Cares, biodiversity means the variety of life on Earth or in an ecosystem. Every species plays an important role in the ecosystem or in the world, no matter how big or small. A way to incorporate this into easier terms is the food chain or food web. Without a certain species in the cycle, you’ll be losing another species and so forth (Shah, 2014).

The widely debated sixth extinction event, the Holocene extinction, is a man-made “weapon” of mass destruction that has caused over 1000 extinct species in the past 500 years (Brannen). A mixture of deforestation, climate change, and other human-impacted effects has made species die off 10 to 100 times faster than the usual background species extinction (Brannen). Well known creatures such as the Dodo Bird, Passenger Pidgeon, Tasmanian Wolf, and Golden Toad have all died due to the lack of care humans have shown for the natural world. Smithsonian paleontologist Doug Erwin, however, still maintains that the Holocene extinction is fake. Though humans have accelerated the extinction of some species and negatively impacted the environment, the actual amount of recent extinctions is almost insignificant. Compared to over half of all species dying off, a few thousand lost animals make nearly no mark in the fossil record (Brannen). Most animals and plants are not, or do not die in ways, suitable for fossilization. This makes the fossil record extremely incomplete. Some scientists estimate that the fossil record shows less than one percent of species that have actually lived. This means that only a truly massive extinction could cause a noticeable change in the record, so the Holocene extinction is most likely not occurring. Still, Erwin cautions us to watch our impact on the Earth and make sure

These also consisted of a pair of die-offs, apparently involving massive glaciation and a resulting fall in sea levels. The cause of this glaciation remains a mystery, but one idea was that land plants actually caused it, pulling so much carbon dioxide out of the atmosphere that global cooling resulted, McGhee explained. Curiously, even though the end-Ordovician led to a huge loss of life, in a way it actually had very little impact on the persistence of lineages. Although the four other Big Five extinction events led to huge changes in which

This extinction event has been dubbed the “Sixth Extinction” by many catastrophists (scientists who study mass extinction events) and is considered to have the disastrous potential to wipe out the majority or all of life on Earth: including humans. One of the reasons why Kolbert was able to effectively convey this message to her readers is because her book exposes her readers to several environmental problems that are relatively unknown to the general public, by using several first-hand accounts of her visits to several fragile and diverse ecosystems across the world, where the effects of climate change and other environmental issues can be visibly observed to be taking a significant toll on local biodiversity.

Throughout the longevity of our Earth’s biota, there are recorded times in which the majority of the pre-living fauna and flora were seemingly decimated. According to our fossil record, these bouts of decimation have totaled to five individual instances throughout the existence of life on Earth. Many scientists agree in saying that, humans as species are the main cause for current sixth mass extinction. Some opponents to this theory claim that label of our worldwide ecological state as a ‘sixth mass extinction’, is just an “emotional charge that makes the problem seem cosmic and overwhelming” (Brand). This however is not a legitimate statement when taking into account the sheer magnitude of human involvement and activities that has added

Over 98% of all organisms that have lived on Earth are now extinct. A mass extinction event occurs when a large number of species die out within a small time frame (relative to the age of Earth). Mass extinctions are intensively studied for both cause and effect, as there is usually room for debate regarding catalysts that precede the extinction and the massive influx of new biological species that follows. There have been five major mass extinctions, dubbed the “Big Five,” that have wiped out at least 50% of the species living at those times. The most well known mass extinction of the Big Five, with the decimation of every species of non-avian dinosaur, is the Cretaceous-Paleogene

Since before the industrial evolutions humans have been pumping green house gasses—carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons— into the atmosphere however, it wasn’t until recently that the amounts being produced are shoving the Earth into a sixth extinction. While the causes of this upcoming extinction are constantly debated on it has earned itself the name Holocene extinction. This name is derived from the theory that humans are the main contributors to this extinction. To investigate the cause Elizabeth Kolbert, and American journalist and professor at Williams College, took the world on a wild and saddening journey on the human contribution to this looming extinction in her novel, The Sixth Extinction; An Unnatural History. Not only does Kolbert’s book explain how humans have contributed to global warming and its effects on life on land but also ocean acidification and how life under the sea has changed over the years.
