IX. Read and dramatize the following dialogues:

A: Is the Mediterranean actually dying from pollution? B: Yes, it is, I would say. If pollution continues at its present pace I think that the northern half will be almost dead in 10 years. It would take only 15 years for the whole Mediterranean to become dead as far as marine life is concerned. A: Under the best conditions, how long would it take the

Mediterranean waters to be renewed? B: If you stop all pollution of the Mediterranean now, it would still take about 100 years for the sea to become clean.

A: Is the Mediterranean polluted everywhere? B: Not exactly, because there are several kinds of pollu­tion. Surface pollution, mainly from petroleum product, you find everywhere. Then there is the vast human and industrial pollution generated by the densely populated coasts.

A: Is anything being done about water pollution?

B: There is not much that can be done.

B: I've seen that your chimneys don't throw much dust into the air.

A: Well, we do use electric filters extensively to remove

most of the dust. B: Is there much sulphur dioxide in the smoke? A: The trouble is that some of our coal contains a lot of sulphur, and there is no effective and economic technolo­gy for removing S0₂ anywhere in the world yet. We tried several wet and dry cleaning techniques, but still too much S0₂ left. B: So you could only make your chimneys higher. A: Yes, that's the only thing to do at present. Then the

toxic gases are at least di spersed over a wider area. * » »

B: What do you do to keep the water in your rivers clean? You know that many rivers are now natural sewers rather than water sources. The companies do not care too much about keeping them clean. It costs them too much money.

A: Well, our government passed an environmental protec­tion law, and there is even a minister for this field. It takes a long time to fight pollution effectively in the face of growing industrialization, but we have been successful in some fields. Of course, it costs a lot of money.
