Mass Extinction And Its Impact On The World

We are slowly killing our planet and our co-habitants at such a high rate that some say we are responsible for the sixth mass extinction. In the book The Sixth Extinction: An Unnatural History author Elizabeth Kolbert an American journalist and professor at Williams College travels to different parts of the world to search for evidence that the sixth extinction is in fact happening now. In The Sixth Extinction Kolbert demonstrates the many ways in which humans are speeding up the loss of so many species. The question is, is it possible to stop or even slow down the loss of other species due to human actions? When we think about extinction we tend to think of cataclysmic events such as the meteor that struck Mexico’s Yucatan peninsula 65 million years ago.

In The Sixth Extinction: An Unnatural History, Elizabeth Kolbert discusses past mass-extinction events and argues that we are currently in the midst of another—this time caused by anthropogenic activity. Each chapter focuses on a different species and analyzes how they serve as evidence of this extinction. Kolbert explores both extinct and living species in an effort to show how the past provides an indication of what may occur in the future if humans continue to conduct “business as usual”. In doing this she also describes how science changes over time: as we discover new scientific evidence, old ideas become obsolete. Kolbert ends the book by saying that while humans are responsible for the destruction of biodiversity, they also have the ability to facilitate positive change.

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

By following the understanding of extinctions up to the present day, Kolbert addresses that extinctions are not strictly catastrophic or uniformitarian. Rather, by citing the major and minor extinctions such as the disappearance of the great auk the End-Cretaceous extinction Kolbert proves that extinctions have a wide variety of causes. Finally, with the grim depiction past and present day extinctions, Kolbert moves on to discuss the title topic: The Sixth Extinction. The term Anthropocene refers to the height of human alteration of the planet earth, which is thought to have begun during the Industrial Revolution. As humans dramatically alter the earth and its ecosystems, it is predicted that humans will eventually cause the sixth extinction if the current environmental trends continue. A combination of accelerated climate change, overhunting, deforestation, and natural ecosystem patterns have begun wiping out entire species at alarming rates. Truly, Kolbert emphasizes that all of humanity’s understanding of extinction is pointing to a devastating mass-extinction which could eventually affect the same beings which catalyzed

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

Summary: In a first person journey that brings her readers around the world, Elizabeth Kolbert researches and explains the effects of human domination on the planet and its resources. Using historical findings of previous extinctions in comparison to earth’s present state she attempts to provide cause and warning for mankind’s seemingly apocalyptic future. Her book, “The Sixth Extinction: an Unnatural History” delves deep into the idea that humanity is currently in the midst of the sixth period of extinction since the beginning of all life. Determined to warn the world of its destructive path, she examines the effects the human race has had (and will continue to have) on other species such as frogs, coral reefs, plants, water creatures, and many mammals while giving a brief yet thorough history lesson of the past five major extinctions that occurred prior to the appearance of Homo sapiens.

Nearly two million years ago, the first of our genus migrated through Africa under the species name of Homo erectus, a new organism that walked on two legs, with sloping foreheads and protruding jaws. Later evolving in the Homo sapiens, and then modern Homo sapiens sapiens, the human we know today quickly came into the world’s view as the top of the food chain and the predators of the period. Since their evolution in the Cenozoic era, the population of our species has grown quite literally exponentially, spreading into Europe, Asia, and the Americas. In the year 2017, our population has reached a whopping 7.5 billion - a sign of near reproductive and selective perfection. Impressive without a doubt, but the environmental impact of a predator

Extinction: A Radical History is a book published by writer, professor and activist Ashley Dawson. It was published on the 22nd of April 2016. Dawson talks about multiple broad subjects in his book like how Capitalism is the main source of mass extinction. By doing so, he takes into account the lengthy history of the Homo Sapiens species, their activities and their discoveries and how us, humans, have affected today’s biodiversity, and probably the future of our planet Earth. He also offers solutions but are they realistically possible? Today, we no longer face natural risks like asteroids and comets. As Dawson states we now face anthropogenic risks like climate change and biodiversity loss which leads to a change in the earth’s ecosystem.

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 that numerous species are decreasing in population due to harmful human activities, which could lead to a global disaster.

I was think that is true because this is what happens when you think you have a lot of something and than its gone and than you have none of that stuff left and people don’t think about after they are always think about now and now that its happening people are starting to make changes but its going to take a while because people have routines and its going to feel different because people are so used to doing things that they are not aware that its doing something to

Stephen Gould’s essay “Sex, Drugs, Disasters, and the Extinction of the Dinosaurs” completely agrees with Joseph Williams and Gregory Colomb’s essay “Argument, Critical Thinking, and Rationality.” Gould’s essay deals with three theories for the extinction of the dinosaurs, two of which he argues are entirely invalid because they are not in accordance with the basic rules of argument laid out by Williams and Colomb in their essay. Gould also states that the third theory of dinosaur extinction, natural disaster, follows all the rules that Williams and Colomb espouse, and thus is a sound argument. Gould, Williams, and Colomb all state that the world has a problem with irrational arguments being shoved down people’s throats, and call for a

There have been 5 mass extinctions in Earth’s existence. The names of these are (from most recent to least recent): Cretaceous–Paleogene, Triassic–Jurassic, Permian–Triassic, Late Devonian, and Ordovician–Silurian. The most well known mass extinction, Cretaceous-Paleogene, was theorized to have occurred through a massive comet or asteroid impact. A cold winter created by the impacting object forbid any plants and plankton to carry out photosynthesis. During this time, about three quarters of all life went extinct. This happened approximately 66 million years ago. Most life forms went extinct, with some ectothermic species and tetrapods weighing less than 25 pounds. Although everything seemed to look hopeless, adaptive radiation caused evolution

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.

There have been five well known extinctions on this earth. The one most well known is the mass extinction that ended the dinosaurs. Mass extinction is often described as the elimination of a large number of species in a short period of time. Despite what many think, the elimination of species is almost commonplace at this point. The Earth is currently in the middle of a sixth mass extinction, and it’s been caused by the human race.

The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About
