如果氧氣在地球上消失 5 分鐘,到底會發生甚麼事?
![According to the people over at Unbelievable Facts, this is what would happen to our planet if we lost oxygen for only 5 seconds.
And Chris Hadfield, if you're out there and you'd like to dispute these facts, please do and let us know just how off base we are.](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-01.jpg)
1. 每個在沙灘上的人都會瞬間曬傷。

就算不是在沙灘上、是在戶外的人也是啦!
因為空氣中的氧分子能保護肌膚抵抗紫外線。

2. 白天的天空會是黑色的。
![if-the-Earth-lost-oxygen-for-5-seconds-16](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-16.jpg)
因為能反射光線的粒子變少了,這代表會有一片黑暗、幾乎全黑的天空。
![if-the-Earth-lost-oxygen-for-5-seconds-17](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-17.jpg)
3. 所有未經處理的金屬彼此會瞬間點焊在一起。
![if-the-Earth-lost-oxygen-for-5-seconds-18](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-18.jpg)
因為唯一能防止金屬焊接在一起的物質就是它們表面的一層氧化物。
![if-the-Earth-lost-oxygen-for-5-seconds-19](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-19.jpg)
4. 地殼會瞬間崩解。
![if-the-Earth-lost-oxygen-for-5-seconds-20](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-20.jpg)
因為氧氣占了地殼的 45%。
![if-the-Earth-lost-oxygen-for-5-seconds-21](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-21.jpg)
5. 所有人/生物的內耳都會爆掉…
![if-the-Earth-lost-oxygen-for-5-seconds-1](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-1.jpg)
因為我們會失去大約 21% 的大氣壓力。

6. 所有用水泥建造的建築物都會變成塵土。
![if-the-Earth-lost-oxygen-for-5-seconds-3](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-3.jpg)
氧氣是水泥中重要的黏著劑。

7. 我們的海洋會蒸發,並飄到外太空。
![if-the-Earth-lost-oxygen-for-5-seconds-6](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-6.jpg)
水是由 1/3 的氧所組成,少了它,剩下的氫會轉為氣體狀態,並會使體積膨脹。
![if-the-Earth-lost-oxygen-for-5-seconds-5](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-5.jpg)
8. 沒有了氧氣,氫就能自由飄到對流層上部,最終到達外太空。
![if-the-Earth-lost-oxygen-for-5-seconds-7](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-7.jpg)
相反地,那如果地球上的氧氣加倍了呢?
![NOW, what if we had double the amount of oxygen??](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-8.jpg)
1. 紙飛機會飛得更遠。
![if-the-Earth-lost-oxygen-for-5-seconds-9](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-9.jpg)
2. 我們會變得更快樂、更有靈敏。
![if-the-Earth-lost-oxygen-for-5-seconds-0](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-02.jpg)
3. 多餘的氧氣會增進我們的認知、警覺與體能表現。
![if-the-Earth-lost-oxygen-for-5-seconds-1](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-110.jpg)
4. 車子會更省油。
![if-the-Earth-lost-oxygen-for-5-seconds-10](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-10.jpg)
5. 但…會出現巨大昆蟲。
![if-the-Earth-lost-oxygen-for-5-seconds-12](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-12.jpg)
昆蟲的身體大小取決於大氣中氧氣的比例。
![if-the-Earth-lost-oxygen-for-5-seconds-13](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-13.jpg)
一切都是適中最好,對吧?
![if-the-Earth-lost-oxygen-for-5-seconds-14](http://teepr.com/wp-content/uploads/2015/08/if-the-earth-lost-oxygen-for-5-seconds-14.jpg)
