Extinction

they cannot resist it from happens which is extinction of their own kinds. This issue is what most human just ignore about and they tend not to deal with it. History of Earth shows that there are five major extinction events and the fifth extinction is the one that killed every dinosaur on the Earth surface as a result of an asteroid. Earth is now in the eve of sixth extinction as humanity has become the asteroid that would drive species to extinction even quickly than they should be. Marine…

(2001), and Barnosky et al. (2011) talked about the impact of mass extinction on the biological history of earth. Benton (1995) talked about how mass extinction drives diversification in the biological community, Erwin (2001) discussed on how species recovery occurs after mass extinction and Barnosky et al. (2011) talked about the possibility of future mass extinction based on the comparison between the present and past extinction data. According to Benton (1995), the massive…

65,000,000 years ago, an entire species was killed off. There are so many different theories of how the dinosaurs dissapeared. There are many different ways to explain the extinction which took place 65 million years ago. One of the main reasons was the possibility of a sudden change in the climate or atmosphere. For instance, a nearby supernova explosion could heat up the upper atmosphere, disturbing the ozone layer. Disturbing the ozone layer could produce large ice clouds which would cool…

The Massest of Mass Extinctions With all the post-apocalyptic themed movies coming out of Hollywood, most people are probably familiar with the concept of a mass extinction. In those kind of movies the cause is often a manmade problem, such as nuclear war. However, in the earth’s distant past, we were not around to destroy ourselves. So what happened? 250 million years ago the Permian period came to an end in a mass extinction causing 95% of species living in the ocean to die (Cort, 2006). To…

to Extinction Dinosaurs have captured the whole world’s attention and curiosity. How did they come to be extinct? What factors led to this downfall? Are they completely extinct? All these questions additional to several others have aroused among many scientists. Although the extinction of the dinosaurs was the smallest one it seems to be the most discussed (Meyer, 2016, personal communication). So what was the cause of the end of these grand creatures? In the article “The ‘Great Extinction’…

detrimental to the environment and the people in it because it’s a waste of time and money, it’s dangerous to pre-existing beings, and it’s not environmentally possible to achieve. The idea of bringing extinct species back to life is a poor idea. De-extinction is a waste of time and money because you have to put millions down to start the process and you might not succeed reproducing the animal for a long time. In text 4 it states “Spending millions of dollars trying to de-extinct a few…

Wild animals have been endangered since the loss of the dinosaurs millions of years ago. When there are no more animals of a particular species alive, that specie is called extinction. Moreover, animal such as Florida manatees, leopard, tigers, rhino, whales, and other animal's life are threatened on a daily basis. In the past millions of years' natural cause has had provoked a numerous species disappear from the planet, but lately human hunting activities and the black market are the most…

Sixth Extinction is a book all about the fact that the earth as we know it has proceeded through 5 “waves” of mass extinctions, and is currently in the middle of yet another wave of mass extinction (the sixth). These “unnatural” occurrences have displayed shocking changes to the variety of species on the globe, hence the title: “The Sixth Extinction, An Unnatural History.” 2. What gave people the idea that organisms may have gone extinct because of catastrophes? The term extinction…

we share them with, but what would happen if human beings stopped caring for their planet and completely disregarded any other living creature outside of the human race? Expert biologist, Jeff Corwin, discusses this idea in his article “The Sixth Extinction,” published by the Los Angeles Times. He argues in his article that while there have been preventative programs put into place, human beings are actively destroying our planet and slowly killing off hundreds of species with every…

Aleechia Gill 09/29/16 RFJ 5 Mass extinctions are a number of events in which a large percentage of the species on the planet go extinct and have a great impact on today’s living things. There have been at least five mass extinctions recorded in the history of the Earth thus far. The earth lost more than 75 percent of its species. It is being debated that we are currently in the sixth mass extinction. Graptolites, it began with the filtered-fed animals and colony builders, which disappeared…
