The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who live in areas where there is a lot of lead in the atmosphere can’t think as quickly as other children and are clumsy when they use their hands.

There are other long-term effects of pollution. If the gases in the atmosphere continue to increase , the earth’s climate may become warmer. A lot of the ice near the Poles ma melt and may cause serious floods.

Earth is losing wildlife at a faster rate than at any time in history. This is according to the new "Living Planet Report" from the World Wildlife Fund. The report says the global wildlife population shrank by 60 per cent between 1970 and 2014. The WWF warned that: "Earth is losing biodiversity at a rate seen only during mass extinctions." Researchers state that most of the decline in our animal population is because of "exploding human consumption". There are more and more humans on this planet. We are eating more, overfishing, cutting down trees for beef production, consuming more, and using more energy and natural resources. This has resulted in a massive loss of habitat for animals.The report estimates that only a quarter of the world's land has been untouched by humans. This means human activity has greatly affected animals on three-quarters of Earth's surface. Researchers tracked more than 4,000 species of mammals, birds, reptiles, fish and amphibians. They say the loss of animal life is worst in South and Central America. These regions saw an 89 per cent loss in the population of vertebrates in the past four decades. The WWF wrote: "The astonishing decline in wildlife population...is a [depressing] reminder, and perhaps the ultimate indicator, of the pressure we [put] on the planet." It warned: "We can be the generation that had its chance and failed to act; that let Earth slip away."

quickly filling up Citizens, governments, industries, scientists and business people must work
together in different ways to gradually reduce pollution.

and water, but factories give employment to a large number of people.
Thus, to end or reduce pollution immediately, people would have to stop using many things that
benefit them . Most people do not want to do that, of course. But pollution can be gradually
reduced in many ways. Scientists and engineers can work to find ways to lessen the amount of
pollution that such things as automobiles and factories cause. Governments can pass and enforce
laws that require businesses and individuals to stop or to cut down on certain polluting activities.
True ( T ) or False ( F ) :

airplanes, trains and poisonous gases emitted from factories. Also, waste is dumped anywhere even
in the city where many people are living. The second pollution is sea pollution. Many people earn
their living from fishing the sea, and the fish they catch feed many people. But the sea has become so
polluted from oil spills and factory wastes that the fish are dying. This pollution is not only killing the
fish, but also affecting those people who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more
difficult every day. We must find a good solution that makes the world a better place to live.

In this section you will find after the passage a number of questions about the passage. You must choose the one which you think fits best . Write your answers in the spaces below (1.0pt)

Paper is named for papyrus, a reed like plant used by ancient Egyptians as writing material more than 5000 years ago. The Chinese invented the paper that we use 2000 years ago.

A piece of paper is really made up of tiny fibers, unlike a piece of material. The fibers used in paper, however, are plant fibers, and there are millions of them in one sheet. In addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the paper different colors; resin may add weight and texture.

Where do these fibers come from ? The majority of paper is made from the plant fiber that comes from trees. Millions are cut down, but new trees are planted in their place. Paper may be also made from things like old rags or pieces of cloth. Wastepaper, paper that has been made and used, can be turned into recycled paper. This recycling process saves forest, energy and reduces air and water pollution.

1. According to the passage, the paper that we use was first invented by

A. the Chinese B. the Egyptians C. ancient cultures D. foresters

2. What is the main ingredient in most paper ?

A. resin B. cardboard C. plant fiber D. papyrus

3. According to the passage, the primary source of the plant fiber used in paper is

A. rags B. trees C. fabric D. wastepaper

4. According to the passage, recycling paper is

A. bad for the environment C. good for the environment

B. wasteful D. economical

5. According to the passage, recycling paper does all of the following EXCEPT

A. reduce the need for ink C. save energy

B. save forests D. reduce air pollution
