What Causes Mammals To Be Extinct - 1098 Words

Every year thousands of mammals are killed due to natural causes and human activity. They can be affected by climate change, deforestation, hunting, and littering. Usually leaving them endangered and in most cases extinct. In the world, there are many factors that cause mammals to become extinct. Climate change is a common factor in what causes mammals to become endangered and later extinct. Climate change mostly caused extinction for two out of every three large mammals in the world. Some mammals that went into extinction because of global warming were: Mammoths, Arabian gazelle, Bulldog rat Central rock rat, Columbian hutia, Corozal rat, Corsican shrew, Cuban spider monkey, Curacao sloth, Dark flying fox, Darling Downs hopping mouse, Darwin’s Galapagos mouse, Dinosaurs†¦ etc. Over the years climate change has increasingly been at fault for the massive loss of mammals dying off. Huge loses of mammals are occurring all over the world, or becoming endangered. It starts whe n the little mammals can’t adapt to the rapid changing of the weather then it slowly starts to affects the larger mammals. â€Å"Climate change affects the little guy first and then, through them, the bigger guys. Today we see humans taking out the bigger animals and climate change affecting the smaller animals. So we can expect to see some pretty dramatic changes in the ecosystem† (Barnosky 3). Some might argue that the planet is changing at such a fast pace, that the mammals don’t even have time to adjust toShow MoreRelatedEssay The Extinction of The Dinosaurs1721 Words   |  7 Pagesoff because early mammals consumed all their food and resources, along with feeding on the Dinosaur’s eggs (Norell, Dingus, and Gaffney). They say as mammals continued to evolve, they drove the dinosaurs into extinction (â€Å"What Killed the Dinosaurs†). â€Å"Not only did mammals likely compete with dinosaurs for resources, many species survived the end-Cretaceo us extinction and subsequently came to dominate Earth.† (â€Å"What Killed the Dinosaurs?†). This is primarily because the early mammals were a lot smallerRead MoreThe Extinction of The Dinosaurs1262 Words   |  6 Pagesdifferent theories exist as to why the dinosaurs went extinct. We know for sure most dinosaurs died out around 65 million years ago. The majority of scientists agree on a number of theories as to what brought the end of the dinosaurs. The most popular theory is that an asteroid ended the reign of the dinosaurs. Another theory, massive climate change in the pre-historic atmosphere, caused all the dinosaurs to die. Some scientists believe that mammals out competed dinosaurs for food and other resourcesRead MoreThe Extinction of Pleistocene Mammals Essay1337 Words   |  6 PagesDuring the late Pleistocene, a mystery occurred in which large mammals went extinct in North America while they survived in other parts of the world. Scientists studying the late Pleistocene extinction provided a plethora of explanations, including overkill by humans, extraterrestrial events, and climate changes (Faith and Surovell, 2009). However, there was no unified explanation that they all agreed upon. Taking note of this, J. Tyler Faith and Todd A. Surovell conducted tests to discover whetherRead MoreDinosaur727 Words   |  3 PagesDinosaur Dinosaurs: Extinct or Natural Causes As geologic time goes, all the dinosaurs living on earth suddenly disappeared. How did these dominated and gigantic creatures really die? Was it a slow extinction through natural causes, or did it happen suddenly? These questions give rise to many different beliefs on how the dinosaurs disappeared over sixty-five million years ago. Something happened sixty-five million years ago, at the end of the Cretaceous period that was so devastatingRead MoreHuman Race And Human Population1443 Words   |  6 Pageshabitat of species. The human race has changed so significantly and with the so called development of the human race, it has come at enormous cost to the many other species and especially the larger mammals that also try to inhabit the planet in the least invasive manner. So the question needs to be asked: â€Å"what would the world be like now if we had never existed in the first place?† Well obviously there would not be any buildings or roads or planes flying through the sky or boats sailing across the manyRead MoreTaking a Look at the Tertiary Period720 Words   |  3 Pagesearth started to cool.

Poaching can be defined as the illegal hunting of animals on land that is not the hunters own. Poaching does not only happen in unprotected lands such as the wilderness, but it has also happened in protected lands such as zoos. Animals may soon become extinct because of the high rate of killing the poachers are doing. If animals do become extinct, life would be very different. An example of how lifeRead MoreThe First Ever Demonstration Of Artificial Embryo Twinning1497 Words   |  6 PagesThe first-ever demonstration of artificial embryo twinning was accomplished on a sea urchin by Hans Adolf Eduard Driesch in 1885 (Oppenheimer, 2016), yet the most significant cloning example was attained in 1996, where ‘Dolly the sheep’, the first mammal clone was created by somatic cell nuclear transfer by Ian Wilmut and Keith Campbell (University of Utah, 2016). In 2002, the Council of Australian Governments agreed to ban human cloning and other unacceptable practices and regulate research involvingRead MoreThe Appearance Of Homo Sapiens And The Disappearance Of Various Species Of Large Mammals1514 Words   |  7 Pagesâ€Å"The appearance of Homo sapiens and the disappearance of various species of large mammals† –these words, I believe, demonstrate the theme of Paul S. Martin’s famed hypothesis. Martin’s theory, also known as the Overkill hypothesis, considers that humans were the sole contributors to the Late Quaternary extinction of megafauna that happened in the last 50,000 years in various continents, mainly in the Americas and Australia. According to Martin, as humans started colonizing new areas of the worldRead MoreEndangered Animals Are E ndangered Species1411 Words   |  6 PagesNot many people know about endangered animals or what makes them endangered. Animals have been endangered and going extinct for over 635 million years. Although extinction is a natural phenomenon, it occurs at a natural â€Å"background† rate of about one to five species per year. Scientists estimate that we’re now losing species at 1,000 to 10,000 times the background rate, with dozens going extinct every day. As many as 30 to 50 percent of all species could possibly be heading toward extinction by mid-century
