The exact reason for the Pleistocene extinction is still not known‚ this data implies that top-down forces and humans are the reason the extinction happened. This data is important because during the Anthropocene humans continue to put animals at risk for another extinction. The authors used data from the Pleistocene and recent data to show that high rates of predation and humans could have lead to the extinction. Both carnivores and humans caused the extinction‚ because both were competing for prey

Animal extinction Animal extinction has been dramatically occurring and this is the biggest issue in the planet. The governments and scientists try to figure out the better ways to prevent and preserve the disappearance of animals. Human attitudes‚ degradation of nature and climate change are the causes that lead to animal extinction. I think that if these causes are still occurring without protection and preservation‚ the environment will become in less healthy state by 2050. The world human population

Extinction Extinction is the termination of evolutionary lineage. The most common extinction event is the loss of a species. There are many reasons why a species might die out. Human intervention (either directly or indirectly) has become the leading cause of species extinction (possibly for the last fifteen thousand years). Species and Populations An important distinction must be made between true extinction and extirpation. Extirpation is the loss of a population‚ or loss of a species

According to “Why Bee Extinction Would Mean the End of Humanity” written by Ishan Daftardar‚ Not only would humans be affected but animals a well. Cattles depend on alfalfa and lupins‚ both of which depend on insect pollination. No bees‚ means no milk or meat. The extinction of bees would also affect our fuel and clothing. Canola‚ responsible for fuel and cooking oil‚ needs bee pollination. We need

A number of different theories have been assessed throughout the course of this research to attempt to reach a conclusion as to the reason behind the extinction of the Tyrannosaurus Rex. Although all arguments are credible‚ and supportive with educated information and data‚ the most conclusive theory of all is The Alvarez Asteroid Impact theory. Alvarez‚ a researcher at the University of California‚ discovered a pencil thin layer of Iridium around the rocks in Gubbio‚ Italy. (New Scientist‚

Chace Jensen Dr. Butler ENGL 1103 16 January 2012 A Small Extinction‚ A Big Problem Albert Einstein once said‚ “If the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees‚ no more pollination‚ no more plants‚ no more animals‚ no more man” (“Einstein Once Said…”). After careful thought on this matter‚ this can be a scary concept to process. Millions of years have passed with the honey bee gracing the earth‚ and in fact‚ the honeybee is

APES Humans’ Affect on Extinction If extinction is a natural part of the world‚ why should we worry about it? Speciation results in new species filling the ecological niche of extinct species. Why should we care if we speed up this process? Biologists say there are four main reasons to care about extinctions. First‚ the world’s species are a vital part of the earth’s life support system. A second reason is that species usually contribute to economic services. The third reason is that it takes

Reintroduction of Wolves to Yellowstone Reintroduction is defined as the act or attempt to bring back a species to its known niche after being threatened to near extinction (Howard and Somers 2009). This was the case for the gray wolf population in Yellowstone National Park‚ as well as throughout most of the U.S. The gray wolves at one point occupied the U.S. in large numbers‚ but when settlers came to America‚ a conflict between the wolves and the settlers became apparent. The conflict was that
