Extinction Of Species Essay

history of earth, several mass extinction events have occurred, thus changing life on earth forever. Elizabeth Kolbert, in her novel The Sixth Extinction, defines mass extinctions as "...events that eliminate a significant proportion of the world's biota in a geologically insignificant amount of time" (Kolbert 16). Five major mass extinctions have transpired that significantly changed biodiversity. Kolbert argues that Earth currently faces a Sixth mass extinction, one caused by humans. Ever since

The History of Earth's Mass Extinctions The four billion year history of earth has witnessed five mass extinctions, and some scientists believe that we are on the verge of the sixth.1[1] If we are in the midst of the next mass extinction, we are in the very early stages of an evolving, and escalating process. The most recent, or fifth mass of the extinctions occurred 65 million years ago at the boundary between the Cretaceous and Tertiary periods. Images of an asteroid colliding with the

Some say that scientist should continue with de-extinction however I believe they should not. I think they should not because people are using them for the wrong reasons, they could bring some nasty disease to us, they could take over the world, it would be worse than a waste, it would be playing God, and because it would make the world more full than it already is. In my opinion we should not go through with the de-extinction because in the article 5 Reasons to Bring Back Extinct Animals (And 5

For or Against De-extinction How cool would it be to have extinct species back on earth. Scientists should stop continuing de-extinction because there are unforeseen consequences like scientists would half to make enough extinct species for at least one healthy sized population, half to stop mammoths from raiding crop lands, and it could become an invasive species that could have more for unseen consequences. Scientists should stop continuing to do de-extinction because scientists would have to

a display of many minerals species, also known as gems. They are arranged into specific categories across the exhibit. The categories are silicates, oxides, organic gems, elementals, and phosphates. These categories are based on general traits of the gems.The second exhibit, The Evolving Planets was about the first species and how the world’s changes affected them before species of today existed. The Evolving Planet exhibit is grouped by six different mass extinctions that occurred before there was

Scientists believe, that the earth in the middle of a sixth ongoing mass extinction, which was given the name of The Holocene extinction due to our modern Holocene epoch. Discussion The Holocene epoch continues from 11 500 years ago until the nowadays and still keep going. Sixth Extinction event can be blamed for significant loss of larger mammals (woolly mammoth, cave lion, cave bear and etc.) during the end of Ice Age extinction event 9 000 to 13 000 years ago, which was caused by climate change.

Five mass extinctions have occurred throughout the history of planet Earth. It is predicted by Author Elizabeth Kolbert, that a sixth extinction may be underway. The Sixth Extinction is a book in the viewpoint of Kolbert and narrates her travels around the globe while she studies numerous wildlife species. Kolbert claims that ¨Those of us alive today not only are witnessing one of the rarest events in life's history, we are also causing it,” (Kolbert, Page 8). Throughout her work, Kolbert claims

Species revival does come with beneficial factors, giving reasons for why it is possible. However, with various types of research, there are causes that result in debate and hesitance to furthering development of the idea. This is very common in the debate of pursuing de-extinction for different points. First, a major question returns of “ where do we put them—what changed in their original habitat that may have contributed to their extinction in the first place?” (Text 3 Lines 25-27) There were

events in climate changes are the mass extinctions that they associated with. Currently we are undergoing the sixth great mass extinction event in our planet's history. While several of these events were due to volcano activity or asteroid strikes, others were due a change in Earth's climate. It is estimated that the Earth is losing species to extinction at 1,000 to 10,000 times the natural rate (The Extinction Crisis, n.d). The primary driver for this extinction event are humans. Several factors are

rulers, yet both of these seemingly unstoppable species fell to an even greater power: extinction. Now humans reside at the top, but as another extinction threatens earth’s ecosystem, humans and billions of other plants and animals may perish similarly to the many species before them. Alexander Pyron explores the degree to which humans should preserve biodiversity and endangered species in his article “We don’t need to save endangered species. Extinction is part of evolution.” Pyron writes to convince
