about when humans may go extinct. In the past, there has been five other mass extinctions. About 450 years ago was the first mass extinction called the late Ordovician, followed by the Devonian, Permian, Triassic and the Cretaceous extinction. All of these extinctions were caused by similar changes. The question is: Are humans in a sixth extinction? The answer is yes, humans are in a sixth extinction because of the extinction of multiple animals, humans, global warming. In the last

Earth has been the host to five mass extinctions (AccessScience Editors, 2014). Mass extinctions are defined as a global event during which at least fifty percent of all species die out in a geological period of time that is too short to allow adaptation (Mass Extinction, n.d.). It is important to note that species are always going extinct, just at a much slower rate than that of a mass extinction. This slow but constant extinction is known as background extinction, and is a normal part of the Earth’s

Imagine what our lives be like if the majority of species disappeared tomorrow. Five major animal extinctions have happened on Earth. These five major mass extinctions caused at least twenty to forty percent of species on Earth to go to extinct (Endangered Species). Signs now show a sixth extinction, mass extinction of animals, is happening. There are some important factors that contribute to mass extinction; they are habitat destruction, pollution, and population. The world is losing about 975 animal

significant biological debates of this generation regards the possibility of a forthcoming, human-induced mass extinction event and what it’s effects would be upon the evolution rate of species. In the search for understanding this possibility and its effects, scientists must look to the past where it is widely accepted that there have been 5 previous periods of mass extinction. The term ‘mass extinction event’ is defined as any period when abnormally large numbers of species die out simultaneously or within

of species, each interwoven within the fabric of life itself. The effects of man on the environment have a negative reaction to all other species. Studies of earth’s history show mass extinction events. Scientist project we are living within such an event. The world is heading toward imminent mass species extinction. A healthy earth may not be possible due to the irreversible effect brought on my man. Endangered plants and animals face the risk of becoming extinct, disappearing completely from

In Elizabeth Kolbert’s book, The Sixth Extinction: An Unnatural History, she details her travels around the world which she has taken to learn more about the rapidly declining populations of several species. With each chapter centered on a different species, Kolbert illustrates the picture of a sixth mass extinction, one anthropogenically caused, a feature that distinguishes this extinction from the five previous ones. Certain species all across the world witness their populations dwindling to abismal

going through what he calls a mass extinction, what that means a whole roll of a species dies out. In her book she goes over the five extinction, and what occurred in the past and the 6th that is currently going on, and how our existences is becoming the issues of these species to go extinct. Elizabeth Kolbert finds mass extinction to be very fascinating but explains that everyone should be very aware and alarmed. She uses scientific research to show these extinctions but as well her personal viewpoints

The Sixth Extinction: An Unnatural History details the continued loss of biodiversity that has occurred since the rise of mankind. Elizabeth Kolbert claims that we are now in the midst of a sixth mass extinction, and that, if precautionary measures are not taken, the loss of biodiversity would be catastrophic. Chapter one begins by describing the golden frogs in the town of El Valle de Antón, and how they were beginning to disappear. The frogs disappeared due to a fungus called Batrachochytrium dendrobatidis

Urbanization is another leading factor to the sixth mass extinction. Brian Czech, in an article titled Urbanization, habitat loss, and extinction in nineteenth-century America, Holley 2 states, “Urbanization endangers species by replacing habitat directly and by depleting resources needed to support urban economies.” People are taking away these animal’s homes and replacing them with resources that only benefit humans and the economy. These animals are forced to survive without the resources and

greatest mass extinction of species since the extinction of the dinosaurs 65 million years ago. In the last two centuries alone the Earth has witnessed world-wide accelerated rates of animal extinction and endangerment, which has taken place alongside industrial progress and rapid human population growth (“Animal Extinction”). So just what is an endangered animal and why should we care? A broad definition is an endangered animal is a species that is threatened with extinction. The extinction of a
