L: Oh, today's weather is awful. The wind blows so strongly and dust blows everywhere.
M: Yeah, it's terrible. But you know, it's not uncommon to have such dust storms in Beijing.
L: Why do the dust storms come so strongly this year? I've never seen such strong storms before.
M: According to the meteorologists view, the dust weather has much to do with the scarcity of rain, the dry air and exposed soil with immature plants in the area.
L: Right, right.
M: And the worsening desertification is another major reason.
L: To tell the truth, I don't like Beijing for two reasons. One is the pollution, and the other is the serious traffic jam.
M: Desertification and pollution caused by the heavy industries and car exhaust emission makes Beijing an entremely dirty city to live in.
L: In China, economic development has often been achieved at the cost of the environment.
M: But Beijing has tightened its environmental protection measures in the past few year.
L: Yes, Beijing hopes to host a "Green Olympics".
M: I hope Beijng starts to take on a new look now.
L: I hope so.
