Comprehension Based Questions with Answers
1. Human populations have always been in flux for the simple reason that every day some people die while others are born. Throughout most of human existence, the number of births was slightly higher than the number of deaths; consequently, world populations grew at a very slow rate. A few hundred years ago, however, the situation began to change, especially in the industrialized world. With advances in nutrition, sanitation, and health, people live longer and more of them reach reproductive age. Thus, for the first time in our species existence, the balance between the number of death and births has been significantly disturbed. Consequently, during the last three centuries or so, the global human population has been rapidly going up. Every year, in fact, the world’s population grows by more than 80 million people. It is, for instance, sobering to recall that for every eleven human beings alive now, only one was alive in the year 1950.

2. On first sight, it may appear that, when it comes to something as valuable as a human being, the more we have, the better off we are. In some ways, this is true. All things being equal, more people are likely to generate more inventions, more technological breakthroughs, and more corporate profits. But. taken as a whole, most ecologists are convinced that the world is already overpopulated. Human populations cannot continue to grow indefinitely for the simple reason that the world itself is finite. More people will need own more food than they need now, and therefore, the process of deforestation will continue so that, eventually. wild trees will vanish. As the population goes up, so docs pollution of rivers, lakes, air, drinking water and soil. With more people, both town and country become more crowded. The quality of life, and the value we place on human life, will continue to erode. When the population is stable, increases in such things as food production, number of physicians, or hospitals are often tantamount to improved quality of life, but such increases often fail to keep pace with population growth. Higher population density is also likely to exacerbate crime, ethnic conflicts, and warfare.
Questions:

3. The American government, to take another example, estimates that some 60,000 Americans die each year from respiratory diseases which are in turn caused by human-made pollution. Fourteen Americans die each day of asthtna aggravated by air pollution three times the incidence of just twenty years ago. Needless to say, the situation in cities like Los Angeles, Kathmandu, Mexico, and Shanghai is even worse. In all these cases, the situation could be considerably improved by controlling pollution and population. Moreover, the world, as we have seen, faces such frightening problems as desertification, depletion of nonrenewable resources (e.g. petrol, natural gas, helium), acid rain, loss of wild species, ozone layer depletion, and the greenhouse effect. A United Nations 1993 document puts it this way: “Population size and rates of growth are key elements in environmental change. At any level of development, increased populations increase energy use. resource consumption and environmental stress”. So, the more people the world has, more severe these problems are likely to become.
Questions:
- How many Americans die each year from respiratory diseases?
- What is the position of Kathmandu regarding population?
- What is the frightening problem before the world?
- What are the key elements in. environment change?

4. Thus a large and rapidly growing population make decisive contributions to all environmental problems. In the long run, efforts to save the biosphere depend impart on our species ability to roll back its numbers. Yet, there is a bright side to this otherwise grim tale. History and common sense tell us that we can control population growth. The German and Swedish population, for example, defy world trends and are actually declining. In such overpopulated countries like China, Thailand, and Egypt the rate of population growth has solved down remarkable, thanks to concerted government action. How do these countries manage to reverse, or slow down, population growth? Many factors account for these remarkable declines: modernization, literacy, media campaigns, readily available family planning and contraceptives. equal economic, educational, and legal opportunities for Women. Human beings thus know how to control their numbers. What they have been lacking so far as the resolve to make use of this knowledge.

5. Let us move to another long term problem: the state of the world’s trees. Owing to rapid population growth, poverty, and other factors, many third world people are forced to move into harvest, clear, burn, or, cultivate tropical forest. Thus, population pressures – along with new technologies and the affluent lifestyle of some people exacerbate the problem of deforestation. A country like Nepal has just so much arable land. So, as the population grows, more and more people are forced to convert forests into farmlands. They must also cut down more and more trees for fuel. The people of rich countries are also guilty. To satisfy Westerners’ insatiable demands for hamburgers, more and more tropical rain forests in countries like Brazil are cleared and converted to pastures. Some rich people also buy mahogany furniture, newspaper, and other paper products in vast quantities.lt are frightening to recall, for instance, how many trees must be felled to just produce the Sunday edition of the New York Times! Many forests are also damaged by pollution, tourism, construction of houses and factories, and similar practices. Moreover, the productivity and general health of the world’s forests are threatened by such things as the greenhouse effect, ozone layer depletion, airborne pollution, and acid rain.
Questions:
- Why are people forced to move into the harvest?
- Why does deforestation take place?
- What is frightening to recall?
- What is threatening for human beings?
- Find the word in the passage which mean “land for grazing of cattle.”
Answers:

must be felled to just produce the Sunday edition of the ‘New York Times’. - The productivity and general health of the world’s forest is threatened by such things as the Green House Effect, Ozone Layer depletion, airborne pollution and acid rain.
- Pastures.
6. The deforestation crisis is not new. Many earlier civilizations including those on Middle East, New Mexico, and Easter Island, precipitated their own decline through over-population and deforestation. The difference is that we are destroying our forests faster, and on a larger scale, than ever before. Earlier in this century, forests covered around 40% of the earth’s total land area. By this century’s end, that figure will stand at about 25%. The destruction of the forest, in turn, contributes to such things as the greenhouse effect, irreversible loss of many thousands of species of plants and animals, landslides, soil erosion, siltation of rivers and dams, droughts, and weather extremes. For instance, as the trees of Nepal are cut down, its topsoil is gradually being lost and its rains are likelier to cause devastating floods in India and Bangladesh. The eventual consequences of massive and ongoing deforestation are uncertain, but they are likely to damage the quality of life on earth, reduce the number of life forms that share the planet with us, and hamper the ability of the biosphere to sustain life. Humanity can continue to fell trees, cross its fingers, and hope for the best. Or it can take hold of its future and reverse the process of deforestation.
Questions:
- What happened to earlier civilization?
- What does the destruction of forest contribute?
- What is the cause of flood in India and in Bangladesh?
- What may be the eventual consequences of deforestation?
- Find the word from the passage which means “hinder”.
Answers:
- Many earlier civilizations, including those of middle East Mexico, and Easter Island precipitated their own decline. This was only due to overpopulation and deforestation.
- The destruction of the forest, in turn, contributes to such things as the greenhouse effect, irreversible loss of many thousands of species of plants and animals, landslides soil erosion, siltation of rivers and dams, droughts and weather extremes.
- As the trees of Nepal are cut down, its topsoil is gradually being lost and its rains are likelier to cause devastating floods in India and Bangladesh.
