to indicate the correct answer to each of the questions

One of the most urgent environmental problems in the world today is the shortage

of clean water. Having clean drinking water is a basic human right. However, 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. Yet, they are being destroyed by the massive volumes of industrial effluent which

pour into the lake every day. Even though laws have been made, the governments do 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 sixteen countries regularly throw

industrial wastes a few miles offshore.

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

it. What should we do to save this precious source?
