A load of rubbish

Line

In the UK, people are finally starting to listen to the message about recycling. British families now recycle about 22% of their waste. Only for five years ago, the figure was 10%. That’s good news for the environment- but there’s a lot more than to do. Some other European countries, like Germany and Holland, already recycle about 60% of their waste and that’s the goal for the UK.

Households in England which produce 25 million tons of waste a year. More than half of this is garden waste, paper, cardboard and kitchen waste – with which people could recycle. They could also recycle plastic, wood, glass and aluminum cans. In fact, if everybody in the UK was recycled all of their drink cans, there would be 14 million fewer rubbish bins of waste each year.

Recycling isn’t the only way to reduce the amount of rubbish what we throw away. More than 40% of the waste in our bins is packaging from shopping. If we changed the way to we shop, we could easily reduce the amount of waste. For example, street markets and small shops often use less packaging than supermarkets. And being of course, if we grow our own vegetables, there wouldn’t be any packaging at all.

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 where 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.

A. acid rain B. industrial pollution. C. safe water shortage. D. population explosion .

III. Read the following passage carefully and choose the best answer to each question. Identify your answer by writing the corresponding letter A, B, C or D on your answer sheet.

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 where 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.
