In the end of 2019， an unprecedented virus sneaked into the human world， and messed up peoples life in merely a few months. Confronting with such a disaster， people started to realize that although the modern technology had brought human dominance to a new high， people were still helpless when facing the tiny virus. In fact， natural hazards bear more power than people can image. Battling against locust plague， earthquake， tsunami， tornado， and many other natural disasters， human beings wrote their history of development.

2019年底，一種從未見過的病毒悄悄潛入人類世界，短短數(shù)月間，給中華大地帶來災(zāi)難性的影響。很多人方才發(fā)現(xiàn)，即便人類科技已經(jīng)發(fā)展到幾乎可以上天入地，卻依然對這小小的病毒束手無策。事實上，不只是病毒，蝗災(zāi)、地震、海嘯、龍卷風……自然界的威力遠比我們想象的要大。人類的發(fā)展史，在很大程度上來說，就是一部與大自然相對抗、相平衡的歷史。
