Conservation conflicts arise when natural resource shortages develop in the face of steadily increasing demands from a growing human population. Controversy frequently surrounds how a resource should be used , or allocated , and for whom. For example , a river may supply water for agricultural irrigation, habitat for fish , and water-generated electricity for a factory. Farmers , fishers , and industry leaders vie for unrestricted access to this river , but such freedom could destroy the resource , and conservation methods are necessary to protect the river for future use . Conflicts worsen when a natural resource crosses political boundaries . For example , the headwaters , or source , of a major river may be located in a different country rather than the country though which the river flows . There is no guarantee that the river source will be protected to accommodate resource needs downstream . In addition , the way in which one natural resource is managed has a direct effect upon other natural resources . Cutting down a forest near a river , for instance , increases erosion , the wearing-away of such as fish and important aquatic plants that require clean , clear freshwater for survival.

When do conflicts decline ?

A. When eroded soil and silt cloud affect many organisms

B. When natural resource shortages increase in the features of gradually increasing demands from human population.

C. When freedom could destroy the resource.

D. When a natural resource crosses political organisms.

Read the passage and mark the letter A, B, C or D to answer the following questions.

Environmentalists often fear that tourists will trample all over sensitive natural resource areas, but tourism may bring the needed and only economic incentives to help drive conservation, said Bynum Boley. Ecotourism and natural resource conservation already have a mutually beneficial relationship that is ideal for creating a sustainable partnership.

"Ecotourism destinations benefit in the form of enhanced tourism competitiveness from the protection of quality natural resources," he said. "Meanwhile, the conservation of these natural resources is increasingly valued since these pristine natural resources are the foundation of the ecotourism industry and the driver of all economic benefits associated with ecotourism."

Tourism is a $7.6 trillion global industry, provides 277 million jobs and is a primary income source for 20 of the world's 48 least-developed countries. It also subsidizes environmental protection and helps protect, conserve and value cultural resources that might otherwise be undervalued by the host community, Boley said. In the newpaper, Boley and co-author Gary Green said that despite past tension between the tourism industry and environmentalists, the two should team up as allies to fight off increasing conversion of land away from its natural state, Ecotourists not only provide a boost to the economy in such places, they can also motivate landowners into keeping the environment in its natural state instead of converting it into something unsustainable. They could also influence the public perception of conservation, Boley explained, which does not often favor environmental protection.

“The public has become increasing less prone to respond to environmental messages,” he said. “Economic messages are needed in order to attract the public's interest.” Too often, Boley and Green said, unique natural resource areas are converted into urban, suburban and agricultural developments without considering their ecotourism potential. In addition to the lost ecotourism revenue, there are a host of negative environmental consequences such as biodiversity loss, water and food shortages and the land being unable to mitigate the effects of climate change. These areas are not valued for their unique attributes or the valuable natural resources they provide, Green said, “so we lose them.” Tourists have historically been seen as having a negative impact on the environment. Critics complain that they violate fragile and threatened natural environments while contributing to greenhouse gases from the increased number of flights to these exotic and often remote locales. While these criticisms are justified, Boley and Green said responsible programs promote education of ecological conservation and environmental sustainability, fostering a greater understanding and appreciation of these exotic areas.

What is the best title for the passage?

A. How to save the environmental resources

B. Ecotourism - benefits and drawbacks

C. The consequences of ecotourism

D. The development of ecotourism

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Early peoples had no need of engineering works to supply their water. Hunters and nomads camped near natural sources of fresh water, and populations were so sparse that pollution of the water supply was not a serious problem. After community life developed and agricultural villages became urban centres, the problem of supplying water became important for inhabitants of a city, as well as for irrigation of the farms surrounding the city. Irrigation works were known in prehistoric times, and before 2000 BC the rulers of Babylonia and Egypt constructed systems of dams and canals to impound the flood waters of the Euphrates and Nile rivers, controlling floods and providing irrigation water throughout the dry season. Such irrigation canals also supplied water for domestic purposes. The first people to consider the sanitation of their water supply were the ancient Romans, who constructed a vast system of aqueducts to bring the clean waters of the Apennine Mountains into the city and built basins and filters along these mains to ensure the clarity of the water. The construction of such extensive water-supply systems declined when the Roman Empire disintegrated, and for several centuries local springs and wells formed the main source of domestic and industrial water.

The invention of the force pump in England in the middle of the 16th century greatly extended the possibilities of development of water-supply systems. In London, the first pumping waterworks was completed in 1562; it pumped river water to a reservoir about 37 m above the level of the River Thames and from the reservoir the water was distributed by gravity, through lead pipes, to buildings in the vicinity.

Increased per-capita demand has coincided with water shortages in many countries. Southeast England, for example, receives only 14 per cent of Britain's rainfall, has 30 per cent of its population, and has experienced declining winter rainfall since the 1980s.

In recent years a great deal of interest has been shown in the conversion of seawater to fresh water to provide drinking water for very dry areas, such as the Middle East. Several different processes, including distillation, electrodialysis, reverse osmosis, and direct-freeze evaporation, have been developed for this purpose. Some of these processes have been used in large facilities in the United States. Although these processes are successful, the cost of treating seawater is much higher than that for treating fresh water

Which of the following is NOT mentioned as a process of convertinging seawater to freshwater?

A. Water evaporation

B. Purification method

C. Steaming and cooling

D. Dissolving chemicals
