    Will Mother Nature or Mankind be the destroyer of planet Earth?

    Every day we are reminded in all media forms that mankind is receiving a wakeup call from Mother Nature informing us that we are slowly destroying the climate of our beloved Earth. But what if Mother Nature's warning isn't a wakeup call, what if it's a slow kiss goodnight for mankind?

    It's a fact that the global temperature has steadily risen during the past 50 years or so, the 17 warmest years have occurred over the last 20 years. The average global rise in temperature is around 0.15 C per decade, which doesn't sound much but, according to this scale it'll have risen by a massive 0. 75 C within the next 50 years. And if the polar ice caps are already melting, it doesn't leave much to the imagination of what the Earth will look like by 2059!

    Would Mother Nature really exterminate mankind? The truth is - yes. Earth has witnessed many species rise and fall since it's creation, the dinosaurs are probably the most remembered amongst them.

    Australopithecus, Cro-Magnon, Neanderthal are to name but three extinct species. Each of those species could have evolved if they had been given the time to do so. Theories abound why they didn't survive, yet we all know for certain they didn't succumb to an asteroid or comet impact in the not too distant past. So what did happen to those species? Could it be fair to suggest that nature saw fit to replace them with a more intelligent species? If so, could this mean that Mother Nature is getting tired of us Homo Sapiens and has decided enough is enough, and we are the next species to disappear and duly be replaced by a higher form? And if you're left wondering where the next form of Homo Sapiens will come from, well that's a question that still defies a definitive answer.

    Earth is a planet which is in a state of flux. Since the creation of the Earth there have been many substantial changes in global terrain and global temperature; the Ice Age is the most memorable and the one which saw the demise of the woolly mammoth.

    The question we must ask ourselves is this: What has Mother Nature got in store for us?

    Will the oceans rise dramatically and our planet become a water world? Will the ozone layer be depleted so much that our Earth is scorched dry by the sun? Will superstorms ravage our lands and bring famine on a global scale? Could it be possible that some future volcanic action would devastate nuclear facilities and release deadly radiation into the atmosphere? Yes, it's a frightening scenario to think that we could be the cause of our own downfall.

    The future for mankind is looking extremely bleak. The clock is ticking…

    大自然還是人類,會(huì)將成為地球的毀滅者呢?

    每一天,各種媒體形式都提醒著我們,人類不斷從大自然那里接到起床來(lái)電,通知我們,我們正在慢慢地破壞著我們心愛(ài)地球的氣候。但如果大自然的的警告不是一個(gè)起床來(lái)電,如果它是一個(gè)送給人類說(shuō)晚安時(shí)緩慢的親吻,這又會(huì)是怎樣呢?

    事實(shí)上,過(guò)去大約五十年里,全球氣溫已經(jīng)穩(wěn)步上升。最暖和的十七年已經(jīng)在過(guò)去二十年出現(xiàn)了。全球平均溫度每十年上升大約0.15攝氏度,這不能說(shuō)明什么,但是根據(jù)這一標(biāo)準(zhǔn),它在接下來(lái)的五十年內(nèi),將會(huì)大規(guī)模地上升到0.75攝氏度。并且如果極地的冰帽已經(jīng)正在溶化,地球到了2059年會(huì)成什么樣,也就心照不宣了。

    大自然會(huì)根除人類嗎?事實(shí)是會(huì)的。自從有了生命,地球目睹了很多物種的出現(xiàn)和消失,恐龍大概是它們當(dāng)中最能讓人記住的物種。

    南方古猿人、克羅馬尼翁人、尼安得特爾人是三種滅絕物種的名字。那些物種的每一類,如果有時(shí)間讓它們進(jìn)化的話,它們已經(jīng)完成進(jìn)化了。有關(guān)為什么他們不能幸存的理論,我們都只能肯定的是,在過(guò)去不太遙遠(yuǎn)的時(shí)代,他們受不了小行星或彗星的影響。所以那些物種發(fā)生了什么事?大自然認(rèn)為用一種更聰明的物種取代它們更為合適,這種說(shuō)法公平嗎?如果公平的話,這是否意味著大自然對(duì)克羅馬儂人已經(jīng)感到厭倦呢?是否意味著足夠就滿足了?是否意味著我們是下一個(gè)消失的物種并且注定被更高級(jí)的形式取代呢?如果你還在思考下一個(gè)克羅馬儂人物種形式會(huì)從何而來(lái),那么這是一個(gè)仍然沒(méi)有明確答案的問(wèn)題。

    地球是一個(gè)不斷變化的星球。自從有地球有生命以來(lái),在全球地形和全球溫度發(fā)生了大量的變化;冰河時(shí)代最令人難忘,它見(jiàn)證了長(zhǎng)毛象的滅絕。

    我們必須捫心自問(wèn):大自然給我們儲(chǔ)備了什么?

    海洋面會(huì)急劇上漲嗎?我們的星球會(huì)變成一個(gè)水中世界嗎?臭氧層會(huì)被嚴(yán)重?fù)p耗以致于我們的地球被太陽(yáng)烤干嗎?超級(jí)風(fēng)暴會(huì)破壞我們的土地,并且會(huì)在全球范圍內(nèi)帶來(lái)饑荒嗎?將來(lái)的一些火山活動(dòng)會(huì)摧毀核設(shè)備并且會(huì)向大氣層釋放致命輻射嗎?會(huì)的,這個(gè)劇本駭人聽(tīng)聞,想像一下,我們有可能成為使自己倒臺(tái)的導(dǎo)火線。

    人類的未來(lái)看起來(lái)很蕭瑟。臺(tái)鐘在滴答滴答地響……
