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!
