Jason and Susan are talking about some environmental problems they have seen.
One problem is that the air is badly polluted. We used to see the stars clearly, but now we hardly ever see blue skies anymore. One reason is that there are more cars on the road these days. It’s also because factories that burn coal pollute the air with a lot of black smoke.
The other problem is that there is too much rubbish and waste in the streets. It’s because people are throwing away things every day. And people are also littering in public places like parks.
These are serious problems for our environment.

problems?

or subway instead of driving.
Susan: Yeah, or ride a bike. These are other advantages of bike
riding. It’s good for health and it doesn’t cost anything!
Interviewer: Great ideas! What about waste pollution?

shopping can help. I started doing that a year ago.

Because they may cause inconvenience.
2. How can we be really serious about saving the earth?
To be really serious about saving the earth, we need to know the
consequences of our actions, or lack of action, and be prepared to
put the greater good before our personal needs.
Imagine that you are an ambassador of environmental protection in your community. Please give a speech on an environmental problem and its causes and solutions to call on people to take action.
Task
Sample
Dear neighbors,
Our neighborhood produces a lot of rubbish every day, such as leftover food, waste food and plastic bottles, but not many people sort out the rubbish.
One reason is that some of us haven’t developed a good habit of rubbish sorting. It’s also because some people haven’t realized how serious the problem is.
To solve the problem, it is necessary for everyone to learn about the rules of how to sort out the rubbish and and put the rules into practice. What’s more, we can volunteer to guide and monitor our neighbors on how to do it properly.
Together our actions can make a difference. Let’s take action now.
Homework
Make a survey on behaviors that are not environmental-friendly in your school and give your advice on such behaviors.
No act of kindness, no matter how small, is ever wasted.
勿以善小而不为。
