Elizabeth Kolbert's The Sixth Extinction

coral survival, growth and reproduction leaving corals bright white. Furthermore, climate change alters the carbon dioxide concertation within the ocean causing variation of pH level through which ocean become more acidic. This event is referred to as ocean acidification. When this occurs, the corals are unable to absorb calcium carbonate needed for skeletal maintenance (Freiwald, et al., 2004). In addition, human population dynamics have increased through the 21th

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 chapter three of The Sixth Extinction, Elizabeth Kolbert describes how the Great Auk went extinct. The Great Auk is considered “the original penguin.” Sadly, they became extinct in the 1800s. They were found in North Atlantic; were it is cold. The Great Auks were killed by poachers. The poachers killed them for food, feathers, and even used them to keep their fires stoked to keep them warm. “You take a kettle with you into which you put a Penguin or two, you kindle a fire under it, and this fire is absolutely made of the unfortunate Penguins themselves.” So the questions are: “How do animals, such as corals, survive in an ever-changing environment?” and “How do humans play a role in increasing or causing

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.

Chapter Seven details ocean acidification and the extinction of coral reefs, which is entirely possible by the end of the

In chapter 11 of The Sixth Extinction, Elizabeth Kolbert finds herself at the Cincinnati Zoo where she is told by Dr. Terri Roth that the Sumatran rhinos are going extinct. This also explains Dr. Roth’s numerous attempts to inseminate Suci, a Sumatran rhinoceros, artificially, but ultimately fails. Kolbert proceeds to talk about the history of the Sumatran rhinoceros, which were very common in the Himalayas, Borneo, and Sumatra. Apparently, a small number of rhinos were sent to American zoos in hopes of reproducing in captivity. Unfortunately, the animals’ diet consisted dry hay, when—contrary to popular belief--green leaves are a staple in the rhinos’ nutrition.

On a day to day basis most people take for granite the lives we get to live, along with putting to much value on the extra things such as materialistic items. Also, the majority of humans are too invested in their personal lives or with themselves that they do not look at the big picture of how what we are doing now will effect us later. As humans are routines in our lives can bring us harm, and within time a we may become the sixth extinction. I believe we threaten human existence as a species and it can eventually lead to destroying our own comfortable lives we have created for ourselves.

The Sixth Extinction is a chapter found in a book titled, “The Sixth Extinction An Unnatural History by Elizabeth Kolbert”. This chapter addresses extinction or the termination of a group. The story takes place in The Panamanian town of El Valle de Anton. The story focuses on the toxic species called the golden frog. For some unknown reason(s), the golden frogs began to disappear.

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

The non-fiction book that I decided to read was, “The Sixth Extinction: An Unnatural History” by Elizabeth Kolbert. What led me to picking this book was that it seemed the most interesting out of all of the non-fiction book selections. Since I already knew most of the reasons why animals went extinct, this book didn’t have an impact me. But when I previously learned about animals extinction, I was impacted because it let me know what happened to dead species species. Examples of this could include learning about the dinosaurs when I was younger or learning about climate change and hunting when I was in middle school.

In recent decades our reefs have been decreasing at an extremely alarming rate. Climate change and ocean acidification play a big role in the alteration of the oceans’ chemistry and the deterioration of reefs. Debates are ongoing whether or not CO2 levels are a direct leading cause to global warming and climate change. Those who oppose

The world we live in is so vast and exciting. Seventy percent of our world is liquid water we call the ocean. In the ocean there are many creatures that each are unique in their own way. However, it is possible that in our lifetime, many marine organisms will become endangered or possibly extinct. The loss of these mejestic marine creatures will be caused mainly because of human advancements in which fossil fuels are used to produce energy. Biodiversity is greatly affected by this increase in acidity. As the ocean acidifies, multiple social and economic issues arise. As humans, we rely on the ocean for almost everything. Much of our food, clothing, cleaning products and cosmetics come from the ocean. With the loss of

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.

Ocean acidification, OA, and ocean warming, OW, have a significant impact on the species that live and thrive in saltwater ecosystems. Coral reefs that are exposed to ocean acidification and increased seawater temperature will show decreased rates of calcification. Therefore, if pH decreases and seawater temperature increases, then calcification rates of coral reefs will decline. Understanding coral reef resilience, the capacity to maintain and recover to coral-dominated states, is important for understanding ways we can try to save the corals, prevent further bleaching and decreased calcification, due to elevated temperatures and CO2 levels.
