Nick: Your home village is so beautiful. There are so many trees, flowers and birds.
Mi: Yes, that's why I like coming back here on holiday.
Nick: Mi, what's that factory? It looks new.
Mi: I don't know. There wasn't a factory here last year.
Nick: Mi, look at the lake! Its water is almost black.
Mi: Let's go closer. ... I can't believe my eyes. The fish are dead!
Nick: I think the waste from the factory has polluted the lake. The fish have died because of the polluted water.
Mi: That's right. If the factory continues dumping poison into the lake, all the fish and other aquatic animals will die.
Nick: Ahchoo!
Mi: Bless you! What's the matter?
Nick: Thanks. Ahchoo! I think there's air pollution here as well. If the air wasn't dirty, I wouldn't sneeze so much. Ahchoo!
Mi: I've come up with an idea about our environmental project! How about giving a presentation about water and air pollution?
Nick: That's a good idea. Let's take some pictures of the factory and the lake to illustrate our presentation. Ahchoo!
