Listen and put the pictures in the correct order.

Ms Bell is our guest today. She works to save our environment.

She is here to answer your questions about the environment.

Let's start. First question.

Hello, Ms Bell. I'm Sandra.

First of all, what should we do at home to protect the environment?

Hello, Sandra. This is a good question.

You should turn off the taps when you brush your teeth. You shouldn't waste water.

You should put your garbage into recycling bins, and you should unplug the TV when you don't watch it.

Thank you, Ms Bell.

What about the air pollution?

We damage the ozone layer when we drive our private cars all the time,

so we should walk more or use public transportation.

Also, chemicals make the air dirty and cause air pollution.

Last question, please.

Ms Bell brought some trees to school. When should we plant them?

We can plant them now. Let's go, kids.
