Answer 1

Natural Disasters - 自然灾害
A natural disaster is the consequence of a natural hazard,such as floods,droughts,mud-rock flows,seismic sea waves,earthquakes,windstorms and the stretching of new deserts which affects human activities.
But do not always blame,it mainly is caused by human being.Because human have cut down too many trees in the forests,dump rubbish into the landfill and invented nuclear bomb.These have badly polluted the environment.
It is very late when we people realize the climates have become abnormal,rainwater rushes down hillsides angrily,and the underground energy goes up to revenge itself on us.The disasters have killed millions upon millions of people,destroyed countless homes,and wiped out numerous pieces of fertile land.
Now more and more people become aware that those disasters have much to do with what we have done to the earth because the earth is our only home-planet.It is urgent for us to stop damaging it,and to do our best to protect it and make it a lovely place suitable to live in,for we have nowhere to go and survive except where we are now.
