Ayaka:

Nowadays, various species are disappearing. Which species are you worried about, Daisuke?

Daisuke:

I’m worried about gorillas. Many of them have lost their homes.

Ayaka:

Why does that happen?

Daisuke:

The forests where gorillas live are rich in rare earth. Rare earth is often used for our smartphones. To get the materials, people have been cutting down the forests.

Ayaka:

That’s terrible. How about you, Nancy?

Nancy:

My concern is coral reefs. About 50% of them have died in the last 30 years.

Ayaka:

Can you tell me why?

Nancy:

Well, the major reason is that the temperature of seawater is rising. This is caused by global warming.

Ayaka:

That’s too bad. We have to find something we can do.
