(1)地理上,中国自然灾害多,地震,洪水
     洪水高发由于中国雨热同季,优点是利于粮食生产,再植物生长最迅速的高温夏
季有充足雨水,缺点是发大水淹死人

(2)粮食产量高的后果是人口迅速膨胀

(3)人口迅速膨胀的后果是人开始侵占河床
    在美国,低洼地区完全闲置,
    在中国,这些地方必须用来种地盖房子,这就挤压了河床宽度,进一步恶化洪水灾害

(4)由于中国自然灾害频发,促成中国产生紧密的社会结构。来应对自然灾害。比如
洪水治理,就需要大范围协调。需求牵引。
西方战争的需求产生了现代科学技术发展。中国自然灾害治理的需求产生了复杂的政治
治理体系。


(5)多难兴邦。没有倒霉事,人类就不需要动脑子解决问题。如果中国没有自然灾害
,中国就不会产生复杂的政治结构。如果几百万年前猴子生存的森林不被破坏,猴子就
不会被迫下地生活。非洲正是因为自然条件优越,气候宜人,所以尼格没有进化压力。

Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
