The number of wild animals on Earth has halved in the past 40 years . Creatures across the land, rivers, and the seas are destroyed as humans killed them for food in unsuitable numbers, while polluting or destroying their habitats.
Hunting is a common activity all around the world, and if performed properly, can have many benefits to us and the rest of the planet. The art of hunting has been around since the beginning of time. Living off of the land used to be a necessity across the world, until the mass production of food came along. In America, people do not usually need to hunt to survive. However, the population of animal species needs to be controlled. Too many of one type of animal can cause a drastic change to any ecosystem. Food supplies decline quickly, leaving many animals without food. Hunting can help keep the population of a group of animals at a good number, making the lives of the other
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.
"Sport" hunting is a violent form of recreation that has left countless animals maimed, and orphaned animals vulnerable to starvation, exposure, and predation. This activity disrupts natural animal population dynamics and has contributed to the extinction of animal species all over the world, including the Tasmanian tiger and the great auk.(1,2)
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
Can you imagine being left to suffer for countless hours after being wounded by an unknown person? As you lie on the cold ground, feeling your life slowly fade away, wondering what you did to deserve this. And then to end it all, a gunshot to the head. Unfortunately, this is how many animals suffer due to big game, trophy hunting. I am an avid proponent that big game hunting is a merciless tactic that needs to be eradicated from society, because it’s evident it burdens the animal to endure suffering, and by slaying these exotic creatures, it increases the population’s prospect to go extinct.
Hunting was originally a resourceful activity and a necessity for survival. It was crucial to use the animal for food, clothes, and tools. With the exception of cultures who still depend on this method, there are many developed areas where this is not longer required. From the lack of needing to hunt animals for resources, sport hunting has emerged. This is the recreational act of killing animals to use as trophies. The problem with sport hunting is that it is an unnecessary and unreasonable activity that presents several dangers. In order to understand why, one must examine the effects it has on animals, humans, and the ecosystem. It is clear that sport hunting should have stricter regulations.
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
This mass extinction, with a rate possibly higher than it’s ever been in the last 65 million years, has been caused humankind ourselves! By cutting down forests and burning fossil fuels, humans are changing the world and not in a good way. The author also mentions how our moving species around contributes to the mass extinction because the new species may become invasive and, in the long run, cause the native species of a particular area to become extinct, such occurrences have already been documented happening in Hawaii. However, not all is bad, as the article also mentions how people are doing what they can, for example the government passing bills or citizens donating to the World Wildlife Fund and other organizations, to help the
Bill Freedmen, author of “Endangered Species—Human Causes Of Extinction and Endangerment” notes, “scientists approximate that present extinction rates are 1,000 to 10,000 times higher than the average natural extinction rate.” These distressing numbers should be acted upon to save the endangered species and avoid the catastrophic change to this planet if these species were to become extinct. In order to produce change, people need to recognize that habitat loss, climate change, and poaching are all factors in why our animal species are going extinct.
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.
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.
