最近有一则报道说,将来如果阿拉伯世界发生战争,不是为石油而战,而是争夺淡水,这并非危言耸听,淡水作为一种资源,越来越受到人们的重视。 水对人类来说,首先是人体的重要组成部分。人体内的水分占到整个体重的70％,在一般的情况下,一个健康人每天大概需要1500毫升的水,也就是说,每天要从体外摄取3斤水,才能满足生命的需要,这些水能调节人的体温,输送营养,排除废物和毒素。有人曾经做过这样的实验,没有食物的情况下,只要有水喝,就能活30天左右。相反,如果断粮又断水,那么只能活一个星期左右了。
In a recent report, it is not alarmist to say that if the war in the Arab world takes place instead of fighting for oil and fighting for fresh water in the future, freshwater, as a resource, has drawn more and more attention. For humans, water is, above all, an important part of the human body. The body of water accounts for 70% of the total body weight, in a general case, a healthy person needs about 1500 ml of water a day, that is, daily intake of 3 pounds of water from in vitro to meet the needs of life, the water Can regulate human body temperature, transport nutrients, eliminate waste and toxins. Someone once did such an experiment, without food, as long as there is water to drink, you can live about 30 days. On the contrary, if the cut off and water, then only live a week or so.
