The Sixth Extinction Essay, Research Paper

So, what is the Sixth Extinction? When is it coming and what is its cause? It is go oning now, and we, the human race are its cause explains Richard Leakey. This phenomenon Leakey argues, is easy comparable with the large five biological crisis & # 8217 ; of geological history, except this one is non being caused by planetary temperature alteration, arrested development of sea degree, or star-shaped impact. It is being caused by one of Earth & # 8217 ; s dwellers. Harmonizing to Leakey, humanity is poised to go the greatest ruinous agent since the elephantine asteroid, which collided with Earth some 65 million old ages ago, pass overing out half the worlds species in a geological blink of an eye. & # 8216 ; The Sixth Extinction & # 8217 ; , written by Richard Leakey, finally highlights humanity & # 8217 ; s mishandling of the natural universe.

Leakey & # 8217 ; s purpose for his book is merely to do people cognizant of the existent state of affairs this planet and its ecosystems are confronting, as a direct consequence of adult male. The statistics that have been compiled for & # 8216 ; The Sixth Extinction & # 8217 ; are dismaying. This is apparent sing: 50 per centum of the Earth & # 8217 ; s species will hold vanished inside the following 100 old ages ; world is utilizing about half of the energy available to prolong life on the planet, and this figure will turn as population leaps in the following 50 old ages from 6 billion to about 10 billion.

Now, with the usage of satellite imagination of much of the universe & # 8217 ; s surface, uncertainties have been laid to rest about whether such dismaying statistics are of existent concern. The reply is beyond a sensible uncertainty that at the current rate of devastation, tropical woods for illustration, will be reduced to 10 per centum of their original screen in the following 50 old ages. The ultimate deduction to all this, as Leakey attests is that the universe is confronting a kind of catastrophe, a clang with many effects. Leakey successfully establishes that consideration must be made that if the farther devastation of life and life & # 8217 ; s support systems is continued, in the terminal, world may really good be one of the species to endure.

Politically talking, many deductions and concerns can be addressed in context of the environmental issues raised by Leakey. These include, but are non limited to: weighing the positions of & # 8216 ; anti-alarmists & # 8217 ; with those who express legitimate concerns ; turn toing issues of over-population, seeing as this such issue is frequently regarded as a cardinal factor taking to environmental jobs, and ; turn toing the construct of redistribution of wealth, which like over population has been to some grade viewed as critical to explicating global-scale solutions. While & # 8216 ; The Sixth Extinction & # 8217 ; serves an amazing intent of educating its readers on adult male & # 8217 ; s mishandling of the natural universe, and the effects of our actions and inactivities, there is nevertheless, no prescription given for any of the quandary aforementioned. Unfortunately, most, if non all the issues presented by Leakey are left unsolved.

For the most portion, & # 8216 ; The Sixth Extinction & # 8217 ; revolves around biological, palaeontological, and ecological constructs and theories, yet Leakey does suggest towards the acknowledgment of some political and economic deductions. Richard Leakey maintains that in the following half century, the universe population will duplicate to over 10 billion. If all these people were to bask the current criterion of life prevalent in the universe today, planetary economic activity would hold to lift at least tenfold. When one considers the effects of this world, one can non assist but inquire at what cost would this economic world be attained?

Possibly the most combative facet of & # 8216 ; the Sixth Extinction & # 8217 ; is itself the digest of dismaying statistics, specifically Leakey & # 8217 ; s claim

that between 17,000 and 100,000 species go extinct every twelvemonth. Many sceptics have argued that due to there non being any certainty on such figures, such conservationist ’scare-tactics’ should non be taken excessively earnestly. Cleverly, Leakey derives an analogy to foreground the existent state of affairs and the prevailing ignorance in the logic of many sceptics. Leakey describes a state of affairs where an asteroid is spotted on a hit class with the Earth. Many people, he argues, would be rightly concerned because such impacts are thought to hold unleashed mass extinctions in the yesteryear. Skeptics on the other manus, would reason that there is no cause for dismay since such theories on mass extinctions as a consequence of star-shaped impacts are pure guess and guessing, and either manner, the asteroid might lose. The point is clear, if there were any agencies of debaring that asteroid, the cost of non making so would be ruinous. In footings of the plausibleness of a 6th extinction, what would the costs be if ignored? Leakey makes a instance for the extinction of world.

Since population is a world-wide concern, the lesson of the narrative is, obviously, concern for the hereafter has to be played out in all states of the universe, non simply in the poorer, developing states as many would believe. If such warnings are ignored, over population will do primary productiveness to fall, as infinite for such productions become non-existent. Leakey makes this combative point through: & # 8220 ; The universe & # 8217 ; s biological diverseness would plump, including the productiveness on which human endurance depends. ( Leakey, 239 )

There are many who merely ignore what is basically this & # 8216 ; Judgment Day & # 8217 ; warning & # 8211 ; the 6th extinction, reasoning that, & # 8220 ; We now have it in our custodies the engineering to feed, clothe, and provide energy to an ever-growing population for the following 7 billion years. & # 8221 ; ( Leakey, 239 ) Ignorantly, the premise is made that the same production forms could widen indefinitely into the hereafter, and that there is no bound to what worlds can pull out from the natural universe.

As a political, economic and societal concern, through the continued devastation of the biodiversity in the aftermath of economic development and prosperity, the universe may really good be pushed over a threshold beyond which it might be able to prolong, foremost, itself, and in the terminal world. Possibly the most distressing deduction established through Leakey & # 8217 ; s work is that if unrestrained, mankind might non merely be the agent of the 6th extinction but besides hazards being one of its victims. ( Leakey, 249 )

As antecedently mentioned, & # 8216 ; The Sixth Extinction & # 8217 ; fails to set up any recommendations that might relieve any of the aforesaid environmental concerns. Yet possibly, another more of import aim is accomplished, viz. the map to educate. Possibly, instruction itself is the first measure to the solution. This is in visible radiation of the fact that as scientific discipline and engineering progresss increase our comfort ( at least a choice few in the universe ) , such amenitiess end up blinding us to the world of the planetary environment. In other words, many ne’er get to see the relationship between inputs and end products of our interactions with the natural universe.

The greatest challenge confronting humanity in the following century is acknowledging the complexnesss of the natural universe including our mutuality with in. In amount, Leakey made the point that while the day-to-day film editing of tropical woods and invasion on wild home grounds is a less dramatic procedure than an star-shaped impact, the terminal consequence is the same. In prosecuting our ain aims, we operate as though the natural universe can defy our actions without presuming any injury. As Leakey would reason, we do so at our hazard.
