The Role Of Anthropocene And Its Effects On The World

There have been five major extinctions during the 4.6 billion years of Earth’s history. The Ordovician, the late Devonian, the Permian, the Triassic-Jurassic, and then the K.T. Cretaceous-Tertiary, the one that killed all of the dinosaurs. Currently, we are living in the new epoch, called the Anthropocene, the age of man. Anthropocene is known as the time of humans, which is characterized by the impact of humans as a fossil record for the future. While the extinction that happened 65 million years ago, causing the dinosaurs to go extinct, occurred naturally when an asteroid struck, the sixth extinction event we are experiencing now is directly identifiable as caused by human activity, such as habitat destruction and over-fishing. Of the past five mass extinction events, although by different causes, they have one factor in common, a massive increase in carbon dioxide levels. More than half of Earth s terrestrial surface has been altered due to human activity, resulting in dras tic deforestation, erosion and loss of topsoil, biodiversity loss, and extinction (Marine Bio, 2016). Global warming is the biggest problem that Earth is facing at this moment. Some causes and effects of global warming are deforestation, ocean acidification, burning of fossil fuels, and greenhouse gas emissions. Through the burning of fossil fuels, we are reversing geological history. During the Gulf oil spill, almost 5 million barrels of oil were spilled, but this is nothing compared to dailyShow MoreRelatedThe International Union Of Geological Sciences1259 Words   |  6 Pagesthe term â€Å"Anthropocene† and have declared that our planet has entered an entirely new epoch. The Anthropocene is regarded as the present time in which our everyday actions have impacted the planet in potentially irreversible manners in terms of environment and climate. Evidence shows that humans have induced exponential changes in biochemicals that have polluted the oceans killing off several animal and plants species while altering the composition of the atmosphere. The Anthropocene is a majorRead MoreThe Drowned World, Comedy, And Elegy1704 Words   |  7 Pagesdrastic effects go hand in hand when it comes to evaluating aspects of the Anthropocene. Literary forms such as tragedy, comedy, and elegy play an influential role in the discussion of these subjects, shaping the way they are interpreted and comprehended. In J.G. Ballard’s The Drowned World, the use of these literary forms frame the ideas of how climate change affects a future Earth and what that means for humanity. Furthermore, this work manifests different emerging trends of the Anthropocene suchRead MoreThe Effects Of Humans On The Global Ecosystem Essay1131 Words   |  5 Pageson how to save the animals in danger. If they are saved, then they would no longer be the animals that were before. Humans have had a large global impact on the Earth and â€Å"the effects of humans on the global environment have escalated (Crutzen). This can be called the Anthropocene to some scientists. The Anthropocene is â€Å"a new geological epoch in which human activity, more than any other forces, steers change on the planet (Mooallem 3). There is also â€Å"evidence of widespread human impact onRead MoreThe Nature Of Sustainability : A Human Nature Hybridity Essay1820 Words   |  8 Pageshealth of the environment. While humans have accepted this view of environmentalism for living in the Holocene epoch, political environmentalist Paul Wapner proposes a renewed definition of environmentalism that has emerged in the Anthropocene epoch. Wapner sees the Anthropocene as an epoch of human geological influence, where humans have inflicted a signature on the earth leaving it â€Å"independent of human experience† (2). That is to say, humans have embedded themselves into the earth systems, resultingRead MoreEnvironmentalism Is Not A New Concept Essay1809 Words   |  8 Pagesimprove the health of the environment.
