A Brief Note On Animal Extinction And Its Effect On Society Essay

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.

Extinction: A Radical History is a book published by writer, professor and activist Ashley Dawson. It was published on the 22nd of April 2016. Dawson talks about multiple broad subjects in his book like how Capitalism is the main source of mass extinction. By doing so, he takes into account the lengthy history of the Homo Sapiens species, their activities and their discoveries and how us, humans, have affected today’s biodiversity, and probably the future of our planet Earth. He also offers solutions but are they realistically possible? Today, we no longer face natural risks like asteroids and comets. As Dawson states we now face anthropogenic risks like climate change and biodiversity loss which leads to a change in the earth’s ecosystem.

One cause why some animals are going extinct is because of hunting. The animal(s) kills other animals and people then kill that animal(s). According to U.S Department of Agriculture it mentions that, “In 2010 wolves killed 570 adult cows and 1,990 calves (baby cows) in Idaho. Montana had 440 adult cows die and 852 calves. Finally, then Wyoming with 74 adult cows and 511 calved dead from wolves.” There are more wolves in Idaho then Wyoming and Montana which also means that more

There are several hypotheses that are used to explain the causes of mass extinctions. Climate change, the warming or cooling of global environments over a short period of time, can lead to other occurrences. Shifts in climate can cause extinction by

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.

There have been many scientific studies conducted to prove and disprove the many theories. However, scientific evidence indicates that both gradual climate changes and sudden catastrophic events have caused past extinctions. The question now is if the sixth extinction will be the result of a sudden catastrophe or a more gradual event caused by humans. The effects that humans are having on the earth is often the subject of debate among scientists and ecologists. Data exists that proves human innovation and expansion has contributed to decreased air and water quality as well as global

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.

The study focused on the impact of the change in human behaviors on the extinction of animal species. It was found that change in human behavior to activities such as domestication of wild animal species, hunting, and encroachment of their natural habitats were some of the ways humans are impacting on animal species. The study was concluded that restrictions need to be enacted to ensure that domestication and hunting of wild animal species do not disturb the structure on the natural ecosystem and the root causes of natural habitat encroachment such as growth in human population need to be checked to prevent further encroachment.

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

There is little question around the world many more animals are being driven to extinction

Several man-made threats have accelerated extinction rates across the globe, such as global warming, pollution, and introduced species. Current extinction rates

Since the beginning of life itself, some species have lived and prospered while other species have gone extinct never to be seen again by mankind. Because of this, some would claim that extinction is natural and not significantly problematic to the world that we live in. Others, however, understand that due to climate change, habitat loss, and poaching, more and more species are becoming endangered which leads to a chain reaction that can be devastating to ecosystems. Species such as the Chinook salmon, gorillas, tropical sharks, and polar bears are all directly affected by climate change, species such as northern spotted owls, Sumatran tigers, and lemurs are greatly harmed due to habitat loss, and species such as the sea turtle, Javan rhinoceros, African elephant, and the Red-Fronted Macaw are all affected by poaching driving them all closer and closer to becoming extinct.

Not to mention “...both groups emphasized that climate change would play an increasing role in species decline…” (Gilman). Climate change is still a controversial topic to some, but many scientists have proven that it’s true. In fact, Neil Degrasse Tyson has given evidence to prove its truth and already informed the world that it’s too late to fix people’s mistakes (Neil). The extinction of species has been caused in certain instances by climate change, which is only getting worse. People have continuously altered the environment to the point of harming other species. The human race’s tendency to destroy an environment greatly impacts the plants and animals residing there. To be more specific, “Human destruction of animal and plant habitat...appear to be having a major impact on extinction rates” (Wilson). Environmental degradation and habitat destruction are both key players in the extinction of many world species. The impact people have had on the environment is much bigger than most anticipate, as they both destroy and intervene with the environment.

The global warming has a significant effect on the animal extinction. We all know that, global warming is what controls the heating and cooling of the earth. The seasonal change in the temperature plays a crucial role on the animal extinction in various ways. As the temperature changes or as the global warming takes place, the animals migrate from one place to another where they feel more comfortable and where they can easily adapt to the environment simply because not all the animals are able to resist certain temperatures. However, when they migrate to a new place, it also requires adapting to the new environment and condition. And when some animals fail adapt to the new environment for not having enough food or not being able to interact

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.
