    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…

    大自然还是人类,会将成为地球的毁灭者呢?

    每一天,各种媒体形式都提醒着我们,人类不断从大自然那里接到起床来电,通知我们,我们正在慢慢地破坏着我们心爱地球的气候。但如果大自然的的警告不是一个起床来电,如果它是一个送给人类说晚安时缓慢的亲吻,这又会是怎样呢?

    事实上,过去大约五十年里,全球气温已经稳步上升。最暖和的十七年已经在过去二十年出现了。全球平均温度每十年上升大约0.15摄氏度,这不能说明什么,但是根据这一标准,它在接下来的五十年内,将会大规模地上升到0.75摄氏度。并且如果极地的冰帽已经正在溶化,地球到了2059年会成什么样,也就心照不宣了。

    大自然会根除人类吗?事实是会的。自从有了生命,地球目睹了很多物种的出现和消失,恐龙大概是它们当中最能让人记住的物种。

    南方古猿人、克罗马尼翁人、尼安得特尔人是三种灭绝物种的名字。那些物种的每一类,如果有时间让它们进化的话,它们已经完成进化了。有关为什么他们不能幸存的理论,我们都只能肯定的是,在过去不太遥远的时代,他们受不了小行星或彗星的影响。所以那些物种发生了什么事?大自然认为用一种更聪明的物种取代它们更为合适,这种说法公平吗?如果公平的话,这是否意味着大自然对克罗马侬人已经感到厌倦呢?是否意味着足够就满足了?是否意味着我们是下一个消失的物种并且注定被更高级的形式取代呢?如果你还在思考下一个克罗马侬人物种形式会从何而来,那么这是一个仍然没有明确答案的问题。

    地球是一个不断变化的星球。自从有地球有生命以来,在全球地形和全球温度发生了大量的变化;冰河时代最令人难忘,它见证了长毛象的灭绝。

    我们必须扪心自问:大自然给我们储备了什么?

    海洋面会急剧上涨吗?我们的星球会变成一个水中世界吗?臭氧层会被严重损耗以致于我们的地球被太阳烤干吗?超级风暴会破坏我们的土地,并且会在全球范围内带来饥荒吗?将来的一些火山活动会摧毁核设备并且会向大气层释放致命辐射吗?会的,这个剧本骇人听闻,想像一下,我们有可能成为使自己倒台的导火线。

    人类的未来看起来很萧瑟。台钟在滴答滴答地响……
