Extinction Of Animal Extinction

A great majority of the extinctions that have occurred throughout history can have the causes traced back to human activity. People realized that extensive and

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.

Summarize: The result of one species extinction could potentially be fatal to the environment. In the animal kingdom, there is a food chain. Keystone animals, are the key ingredient to the food chain. When that keystone animals goes extinct, it sets off a chain reaction on the other animal’s food source. This causes one species to flourish and another to dwindle. The environment needs a healthy checks and balance system to keep each animal population under control (Stuart, 1990 ). Humans can cause the keystone animal to become extinct and therefore, responsible for rise and decline of other species, ultimately, throwing the food chain off balance.

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.

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.

When the first species arrived, there have been many species that have become extinct due to natural disasters, natural selection, or even just the dominance of species fighting for survival. When the Industrial Revolution started in human society, we have been the blame for many extinctions such as the Dodo which was hunted to extinction by sailors and invasive species brought over by the sailors (OneKind). Some of the threats to species due to humans are habitat loss, pollution in the atmosphere, and overpopulation. This could mean another extinct species creating another bullet point on the list of extinction.

Unlike mass extinctions before this, “Unlike past mass extinctions, caused by events like asteroid strikes, volcanic eruptions, and natural climate shifts, the current crisis is almost entirely caused by us — humans.” The earth is currently experiencing its sixth mass extinction caused by human behaviour and this can be seen by assessing modern extinction rates due to human activity, human overpopulation and man-made climate

The current declining of biodiversity is comparable to the massive extinction of many animals over 65 million years ago.

Over 1,000 species die off every year, because of us. We are wiping out species over 1,000 faster than nature can create new ones. There are over 1,000,000 species worldwide. If we keep up the rate of killing over 1,000 species a year by the year 102,017 all species excluding humans will be extinct. It may seem like a long time until you think about all of the animals on a worldwide spread, gone forever. Some that are already extinct are the well know dodo bird, passenger pigeon, and the sea mink. All due to poaching.

Species are at risk from human activities and other things, one primary cause of human extinction is that humans are overpopulated on planet Earth. . From the land destroying, and people overfishing in oceans and lakes have driven half of the world's marine and land species to extinction. For humans

There are many forces that can lead to extinction, not just the current phase of humans killing off the animals.

A clear analysis shows that extinction has occurred so much, that they do not only list the animals, they have to list a broader and more general title, meaning extinction is so worst that writing the names of the animals' name will be too much, and writing the whole broad title will include thousands of animals under one title. With 41% amphibian, 26% of mammal species and 13% of birds. It is extremely alarming. And the extinction only includes the species that has been found and labeled by us, there are much more species that have not been discovered if any of those species goes extinct we would have never known they existed in the first place. The fact that the sixth extinction is compared to the mass extinction of wipe out that happened

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.

Mass extinction is defined as a moment in time where a widespread event wipes out the majority of living plants and animals. There have been five extinctions and no matter what, it’s just bound to happen. I have always believed that extinctions are really a normal part of evolution. However, after watching this documentary, extinctions are happening at a faster rate than usual. We, humans, are the very ones that are contributing to it. Doing everyday things that we don’t even think about would affect the world. Technology is so advanced today that we are able to fix things and save species. But then again, how do you save species when there is at least over 8 million species on earth? How do you decide which one to save? Where do you even begin?

There are many species that are on the verge of extinction. Earth's animals are on the brink of a sixth mass extinction, where massive amounts of plants and animals die off. The main reason why animals are becoming endangered or are on the verge of endangerment is because of human beings. Humans are causing the extinctions by deforestation, poaching, and contributing to pollution.
