Mass Extinction Compare And Contrast

I think the title “The Sixth Extinction” is appropriate because 5 mass extinctions (the Big Five) have already occurred, and we are on the brink of a 6th one. I also believe the subtitle “An Unnatural History” is fitting due to the not-so natural ways that animals become extinct. Whether it be because of BP fungus, asteroids, carbon dioxide-emitting sea vents, deforestation, and other various human activity. The only other title suggestion I have would be “The Anthropocene Extinction.”

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

In this world is the first mass extinction that is being caused by another organism (us). The sixth extinction start really with the industrial revolution. To thought about the characteristics of first industrial revolution. It was being in the first step taking raw materials from the earth. Furthermore, business take materials, make products who gives many waste, powered by fossil fuel-derived energy. The industrial revolution be wasteful because it abusive and focused on labour productivity. More product per hour. All those attributes must be changed to move business to the sustainability. The three major problems businesses face are: What it takes? What it makes? And what it wastes? The Ecology of Commerce by Paul Hawken arrangements with the effects of industrialization on the environment. Hawken's takes the point of view that the environment is being ruined by the economic system. The economic system and the processes of industrialization do not imitate the natural cyclical processes, Finish the death of birth (where the waste in one step becomes the food in another step). In this kind of ecosystem, there is no waste; everything is reused. If industry had imitated this kind of system, there would be no problem with tiredness of resources and damage to the earth. However, this isn't how industrialization works; instead, the process is linear. Business processes result in a great deal of waste, which does great damage to the environment. For example, industry relies on fossil fuels like oil and carbon-based fuels. This creates a problem with carbon dioxide, which is harmful to the

The most surprising aspect of this article was that humans today are said to be the cause of the sixth extinction. This was surprising to me because I did not know our planet has been impacted so much by our existence. Also, it surprised me because I have recently heard about how we were trying to fix our planet. The sixth extinction is horrible. Also, because we do not yet know the full extinct of our actions, the ramifications of our actions have yet to harm humankind. If we keep going we may not exist in 1,000

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.

In the book The Sixth Extinction written by Elizabeth Kolbert there are a lot of examples that are going on in the world today and also examples of things that started when the first human being was around. This book talks about how we are in the sixth mass extinction, and that is caused by humans. Overall the book goes chapter by chapter and talks about the different mass extinctions there have been, and how they were caused, but also the book talks about different species that have gone extinct and the reasons why. For example the book talks about golden frogs that are located in Panama and how they were seen everywhere located in El Valle de Anton, but they suddenly started disappearing. They were disappearing because of a chytrid fungis cause by humans, when humans travel they were bring this fungis to different places, this ended up killing the frogs (Chapter 1, Kolbert). That is just one example, but throughout the book Kolbert talks about different extinctions like this and what caused them.

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

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.

The chapter then moves to Kolbert’s experience with ammonite fossils in Princeton, New Jersey. While the distinct spiral shape of ammonites is well-known and agreed upon, the exact shape and structure of the mollusk in the shell is heavily debated. Ammonites are then compared to nautiluses, living animals that heavily resemble ammonites, in terms of why one species was able to flourish, while the other was wiped out. Chapter five lays out the concept that ordinarily species go extinct at a gradual, slow pacing, unless of course there is a catastrophic event, such as human meddling or a giant asteroid, in which case the extinction process is expedited. The extinct species that Kolbert studies in this chapter is the graptolite, a long, thin, V-shaped marine animal. The extinction of grapolite is theorized to be due to a drastic change in the ocean. Kolbert additionally tells a theory that, in the future, rats will be the predominant race on Earth, overtaking even humans. This is all based on the fact that humans have too drastically changed the Earth’s composition and wherever humans go and change, rats are there to follow. Thus we are ushering in the Anthropocene, or the “age of humans,” a time period in which humans have wrecked up the planet to the point of no

A mass extinction is an event in which at least 25-75% of species in the global environment are eradicated in a short period of time. Where as a regional extinction event is when the extinction is confined to a specific zone. Five mass extinctions have occurred throughout time, two of the most well known of these are the Permian and Cretaceous extinction events.

In a summary, Kolbert explains the extinctions of a variety of different major animal species that became extinct. She also explains that if trends in the environment continue that the biggest extinction in history will occur soon. If global warming, deforestation, and glaciers continue to melt she says that more and more species will continue to become extinct. She explains how humans need to be more conservative and careful with what they’re doing to prevent extinction.

It was caused by continued growth of the ice caps and it killed 70 percent of all species. “The third extinction is the most devastating in the planet’s history – as many as 96 percent of all animal species died out during it”(Regenerative. “6 Mass Extinctions.” REGENERATIVE.com, 16 Dec. 2016,). This extinction was 225 million years ago, among the Permian era. A super volcano eradicates most of all life! Of all life currently on Earth is descended from the 4 percent of species that survived this extinction(Regenerative. “6 Mass Extinctions.” REGENERATIVE.com, 16 Dec. 2016,). The forth mass extinction was 200 million years ago in the Triassic era. It was caused by an asteroid crashing into the Mexico’s Yucatan Peninsula (Regenerative. “6 Mass Extinctions.” REGENERATIVE.com, 16 Dec. 2016,). The asteroid through dust and ash in the air and blocking the sun and killing 50 percent of all life. The fifth and final extinction was 65 million

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.

Habitat destruction, deforestation, ozone depletion, global warming, and poaching. These actions and ecological happenings are creating a world where animals are going extinct at rapid rates. Our world is on the brink of what scientists believe is the sixth mass extinction. Unlike the five previous mass extinction, the latest one killing a majority of the dinosaurs, the main causes for this current extinction are anthropogenic reasons, not natural events.

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.
