The Sixth Extinction Essay

Comparing and contrasting the mass extinction and the current extinction. Scientist say that we are causing the 6th extinction. An extinction is when all of a certain animal or plant is gone and nothing left of it. In this essay I will be comparing and contrasting these 2 extinctions. Contrasting the mass extinction and the current extinction. The first big thing is that we are causing the 6th one because all the other ones before it was caused by natural causes and this one is manmade like on the

which could possibly have life. The Keplar-186 is the closest planet to Earth that could have life, but the planet is 500 light years away and has a red dwarf star as its sun. Whereas the article “‘Without Doubt,’ a Sixth Mass Extinction Event is Here” explains of how another mass extinction is likely to occur. The article further explains how if present conditions continue then it will take millions of years to recover life. Although, not all researchers are focusing on ecological or exobiological

with problems like the big problem itself. THE BIODIVERSITY PROBLEM Over the last half billion years on Earth, there has been five mass extinctions which succeeded in wiping out ninety-five percent of the planets species. Some experts believe that we are on the verge of the sixth mass extinction. For example, journalist Elizabeth Kolbert, author of The Sixth Extinction, believes that humans are “living in a time of very,

Chris Thomas, a biologist from the University of York, once said that there is a “high likelihood that climate change on its own could generate a level of extinction on par with, or exceeding, the slightly ‘lesser’ extinction events” (qtd in Kolbert 168). Thomas’ knowledge on extinctions may bring insight to the long lasting effects climate change may bring in the future. Climate change is referred to the changes in the climate on a global level, which mainly started with the burning of fossil

Species Extinction and Conservation The problem the world faces other than global warming or poverty is species extinction of animals and plants all around the world. Most everyone either knows about or has some small idea that we there is a problem but it can be a complicated subject to talk about. (Tepper 2010) People have normal worries like global warming, pollution by factories and things like genocide in other countries.(Tepper 2010) The problem people should be thinking about and worry about

seem to be globally threatening, yet the constant waste of certain species of animals and the destruction of an animal's natural habitat will lead to the endangerment and eventually the extinction of the species. Furthermore, many people are unaware that the world is currently in the midst of the largest mass extinction in history. The human population's use of domesticated and wild animals is both horrific and dangerously frivolous. For example, one might examine the usage of vivisection, or animal

global warming and the extinction of 70% of marine life. These two examples are not the only times Earth has experienced mass extinction. An extinction may be viewed as a natural part of evolution that occurs when a large proportion of a particular species completely dies off and ceases to exist. Extinctions are considered to be mass extinctions if the number of species becoming extinct is significantly larger than the normal, natural rate of extinction. These mass extinctions disrupt the entire global

We are currently in the midst of our sixth mass extinction. A bold statement, yes, but a true one nevertheless. There have been five previous mass extinctions, each having been triggered by an cataclysmic event, resulting in at least seventy-five percent of species going extinct. Though, this time around, the blame is being pointed elsewhere. Towards us. Are humans responsibly for the sixth mass extinction? Many seem to think so, including Harvard Biologist, E. O. Wilson, who has estimated around

megafaunal mass extinction took place. It’s still debated whether humans are to blame for this, since this megafaunal extinction happened after the arrival of humans or if climate change is entirely to blame. Fossil evidence has been of great help in finding what factors might’ve caused this extinction. This mass extinction that took place is related to the Anthropocene because if humans were the main cause, humans need to be more careful now because their actions may lead to more extinctions. The observations
