翻开人类的历史,不难发现,灾难总是和人类相伴,姑且不论战争等人祸,单是地震等天灾给人类带来的灾难便触目惊心。地壳会随时移动和裂开,引起地震、火山爆发、海啸、山崩和泥石流等,给人类带来毁灭性的灾难。飓风和洪水肆虐,会给人类带来突如其来的破坏性灾难。疫病这一恶魔,更是一刻也没有停止对人类的侵害。若是被来自宇宙空间其他天体的流星和小行星撞上,后果更是不堪设想。 Open the history of mankind, not hard to find, the disaster is always accompanied by humans, let alone regardless of war and other man-made disasters, such as earthquakes and other natural disasters alone to the catastrophe will shocking. The earth’s crust will move and crack at any time, causing earthquakes, volcanic eruptions, tsunamis, landslides and mudslides, bringing devastating catastrophes to mankind. Hurricanes and floods are rampant, bringing sudden and disastrous catastrophes to mankind. The devil of the epidemic, but also for a moment did not stop the human invasion. If it were hit by meteors and other astronauts from other celestial bodies in space, the consequences would be even more disastrous.
