Can you think of other natural disasters?

Natural Disasters 自然灾害 In the past hundred years, there have been frequent natural disasters, such as floods, droughts, mud-rock flows, tsunamis, earthquakes, hurricanes and sandstorms. The disasters have killed millions upon millions of people, destroyed countless homes, and wiped out numerous pieces of fertile (富饶的) land.

Now more and more people become aware that those disasters have much to do with what we have done to the earth. We have cut down too many trees in the forests, we have badly polluted the environment, we have shocked our own home-planet time and again with extremely powerful explosions of nuclear bombs.

As a result, climates have become abnormal, rainwater rushes down hillsides angrily, and the underground energy goes up to revenge on us. 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.

Discussion

What can we do to protect the environment?

· Throw waste in rubbish bins. Recycle as much as possible. · Use less wood. Plant more trees. Try to make desert areas become green land. · Treat the waste water before pouring it into rivers. Clean the water in the rivers/lakes.

Save water in our daily life. Make smoke harmless before it goes into the air. Limit the number of vehicles. Develop clean energy. …

Let’s enjoy!
