Mary Fisher: Hello, Chen Jie. I thought you were going to Thailand this morning.

Chen Jie: My flight is delayed due to the floods. Other public transportation like trains and ships has also been canceled or delayed.

Mary Fisher: That’s terrible. It seems there have been more floods these years than before.

Chen Jie: Yes. And also the typhoons, wildfire and smog.

Mary Fisher: These natural disasters have caused great damage to our life.

Chen Jie: That’s certainly true. And some of them are caused by human activities.

Mary Fisher: Yes. We’ve burned too much coal and oil and badly polluted the environment.

Chen Jie: Well, it’s lucky that people have decided to make a change.

Mary Fisher: Yes. It’s what we should do right now. And the most important thing is how we can have more people join us.

Chen Jie: I agree with you. If more people work together, it’ll be possible for us to protect our earth and make it a safe and lovely place to live.
