                                                                                                  Aral
                                                                                                   Sea
                         1  READ the excerpt from a lecture about the Aral Sea. Notice the
                   CD2-02
                            words in bold.                                                              Uzbekistan
                                          Asia’s Aral Sea


                       Professor: . . . Now, as we’ve just seen in the first slide, the
                       Aral Sea is in central Asia on the border between Kazakhstan
                       and Uzbekistan. It used to be one of the biggest inland seas
                                                                              1
                       in the world, but most of its water has disappeared. The sea
                                  2
                       has shrunk  to 10 percent of its original size.
                          Some people say that the water level has gone down because
                       of climate change. However, we know that in the second half of the
                       twentieth century, agricultural projects used up the water in the
                       Aral Sea. The Aral Sea used to be home to 24 species of fish. Now,
                       people keep cows and camels on the land next to old fishing ships.

                       Student 1: Have the governments of Kazakhstan and Uzbekistan
                       ever tried to save the sea?

                                                                              3
                       Professor: Yes, they have. In Kazakhstan, they built a dam  to
                       help save the northern part of the Aral Sea, and the water level
                       has risen again. A lot of fish are living there again, and birds have
                       returned, too.

                       Student 2: What about the southern part in Uzbekistan? Has the
                       situation there improved?

                       Professor: No, I’m afraid it hasn’t. Unfortunately, most of the
                       southern Aral Sea has probably disappeared forever.
