VII. Read the passage and choose the best option for each question.
One of the most urgent environmental problems in the world today is the shortage of
clean water. Having clean drinking water is basic human right. But acid rain,
industrial pollution and garbage have made many sources of water undrinkable.
Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal
in Russia is one of the largest lakes in the world. It contains a rich variety of animals
and plants, including 1,300 rare species that do not exist anywhere else in the world.
But they are being destroyed by the massive volumes of industrial effluent which
pours into the lake everyday. Even when law existed, the government did not have
the power to enforce them. Most industries simply ignore the regulations. The
Mediterranean Sea occupies 1% of the world's water surface. But it is the dumping
ground for 50% of all marine pollution. Almost 16 countries regularly throw
industrial wastes a few miles off shore.
Water is free to everyone. A few years ago people thought that the supply of clean
water in the world was limitless. Today, many water supplies have been ruined by
pollution and sewage. Clean water is now scarce, and we are at last beginning to
respect this precious source. We should do something now.
