如果氧气在地球上消失 5 分钟,到底会发生甚么事?
![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. 每个在沙滩上的人都会瞬间晒伤。

就算不是在沙滩上、是在户外的人也是啦!
因为空气中的氧分子能保护肌肤抵抗紫外线。

2. 白天的天空会是黑色的。

因为能反射光线的粒子变少了,这代表会有一片黑暗、几乎全黑的天空。
![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. 所有未经处理的金属彼此会瞬间点焊在一起。
![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)
因为唯一能防止金属焊接在一起的物质就是它们表面的一层氧化物。
![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. 地壳会瞬间崩解。
![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)
因为氧气占了地壳的 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/生物的内耳都会爆掉…
![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)
因为我们会失去大约 21% 的大气压力。

6. 所有用水泥建造的建筑物都会变成尘土。
![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)
氧气是水泥中重要的黏着剂。

7. 我们的海洋会蒸发,并飘到外太空。
![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 的氧所组成,少了它,剩下的氢会转为气体状态,并会使体积膨胀。
![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. 没有了氧气,氢就能自由飘到对流层上部,最终到达外太空。
![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,那如果地球上的氧气加倍了呢?
![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. 纸飞机会飞得更远。
![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. 我们会变得更快乐、更有灵敏。
![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. 多余的氧气会增进我们的认知、警觉与体能表现。
![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. 车子会更省油。
![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…会出现巨大昆虫。
![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)
昆虫的身体大小取决于大气中氧气的比例。
![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)
一切都是适中最好,对吧?
![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)
