Part III Reading Comprehension

Section B

Keep Our Seas Clean A) By the year 2050 it is estimated that the world’s population could have increased to around 12 billion. Of these, some 60 percent will live within 60 km of the sea. The agricultural and industrial activities required to support this population will increase the already significant pressures on fertile coastal areas. Death and disease caused by polluted coastal waters costs the global economy US $12.8 billion a year. Plastic waste kills up to 1 million sea birds, 100,000 sea mammals and countless fish each year. B) One significant impact of human activity is marine pollution. The most visible and familiar is oil pollution caused by tanker accidents and tank washing at sea, and in addition to the gross visible short-term impacts, severe long-term problems can also result In the case of the Exxon Valdez which ran onto a shore in Alaska in 19, biological impacts from the oil spill can still be identified 15 years after the event. The Prestige which sank off the Spanish coast late in 2002, resulted in huge economic losses as it polluted more than 100 beaches in France and Spain and effectively destroyed the local fishing industry. C) Despite the scale and visibility of such impacts, the total quantities of pollutants entering the sea from the long line of catastrophic oil spills appeared small compared with those of pollutants introduced directly and indirectly from other sources, including domestic sewage, industrial discharges, leakages from waste tips, urban and industrial run-off, accidents, spillages, explosions, sea dumping operations, oil production, mining, agriculture nutrients and pesticides, waste heat sources, and radioactive discharges. Land based sources are estimated to account for around 44 percent of the pollutants entering the sea and atmospheric inputs account for an estimated 33 percent. By contrast, transport on the sea accounts for 12 percent. D) The impacts of pollution vary. Nutrient pollution from sewage discharges and agriculture can result in unsightly and possibly dangerous “blooms” of algae (藻类) in coastal waters. As these blooms die and decay they use up the oxygen in the water. This has led, in some areas, to “creeping dead zones” (CDZ), where oxygen dissolved in the water falls to levels unable to sustain marine life. Industrial pollution also contributes to these dead zones. E) Radioactive (放射性的) pollution has many causes, including the normal operation of nuclear power stations, but by far the single biggest sources of man-made radioactive elements in the sea are the nuclear fuel reprocessing plants at La Hague in France and at Sellafield in the UK Waste released from them has resulted in the widespread pollution of living marine resources over a wide area; radioactive elements traceable to reprocessing can be found in seaweeds as far away as the West Greenland Coast. F) Trace metal pollution from metal

mining, production and processing industries can damage the health of marine plants and animals and render some seafoods unfit for human consumption. The contribution of human activities can be very significant: the amount of mercury introduced to the environment by industrial activities is around four times the amount released through natural processes such as weathering and erosion (腐蚀). G) The input of man-made chemicals to the oceans potentially involves an overwhelming number of different substances. 63,000 different chemicals are thought to be in use worldwide with 3,000 accounting for 90 percent of the total production amount. Each year, anywhere up to 1,000 new synthetic chemicals may be brought onto the market. Of all these chemicals some 4,500 fall into the most serious category. These are known as persistent organic pollutants (POPs). They’re resistant to breakdown and have the potential to accumulate in the tissues of living organisms (all marine life), causing hormone disruption which can, in turn, cause reproductive problems, induce cancer, suppress the immune system and interfere with normal mental development in children. H) POPs can also be transported long distances in the atmosphere and deposited in cold regions. As a result, Inuit populations who live in the Arctic a long distance from the sources of these pollutants are among the most severely influenced people on the planet, since they rely on fat-rich marine food sources such as fish and seals. POPs are also thought to be responsible for some polar bear populations failing to reproduce normally. Scarily, seafoods consumed by people living in warm and mild regions are also affected by POPs. Oily fish tend to accumulate POPs in their bodies and these can be passed to human consumers. When oily fish are rendered down into fish meal and fish oils and subsequently used to feed other animals, then this too can act as a pathway to humans. Farmed fish and shellfish, dairy cattle, poultry and pigs are all fed fish meal in certain countries, and so meat and dairy products as well as farmed and wild fish can act as further sources of these chemicals to humans. I) The North and Baltic Seas also contain some of the world’s busiest shipping lanes. 200,000 ships cross the North Sea every year. Many goods transported by ships are hazardous (half the goods carried at sea can be described as dangerous) and loss of dangerous cargoes can result in damage to the marine environment. Chemical tank washings, discharge of oily wastes and wash waters are all significant sources of marine pollution. J) In addition there is always the risk of a major oil spill, a risk made worse by the fact that some of the tankers that routinely travel through still have only one body-frame or have other technical defects and crews who are poorly educated. In November 2002, the Prestige oil tanker went down off the coast of Spain with 70,000 tons of oil on board which polluted 2,0 km of coastline. A few days earlier it had been crossing the Baltic. K) Some sources of pollution have been brought under control by international legislation. Countries which signed the London Convention have agreed to stop the dumping of radioactive and industrial waste at sea. The OSPAR Convention regulates marine pollution in the North East Atlantic Region while countries which signed the Stockholm Convention have committed themselves to the phase out of a number of persistent organic pollutants. Within the European Community, the Water Framework Directive may be expected to bring further reductions in polluting inputs, although it will be over a very long time frame. The

additional benefit of the new EU REACH (Registration Evaluation and Authorisation of Chemicals) initiative, which aims to regulate the production and use of dangerous chemicals at source, remains to be seen.

Working to Improve the Conditions of Everglades National Park A) When many people think of Florida, images of sandy coastlines or theme park rides come to mind. But about an hour south of Miami lies a natural wilderness different

from anywhere else in the United States. Everglades National Park is the largest subtropical wilderness in the country. The park is home to several rare and endangered species. It is also the third largest national park in the lower forty-eight states, after Death Valley and Yellowstone. More than one million people visit the Everglades each year. B) The Everglades is considered one of the great biological wonders of the world. The expansive wetlands stretch across more than six hundred thousand hectares (公顷). It is a place where plants and animals from the Caribbean Sea share an ecosystem with native North American species. Unlike most other national parks, Everglades National Park was created to protect an ecosystem from damage. The Everglades is home to thirty-six species that are considered threatened or protected. They include the Florida panther, the American crocodile and the West Indian manatee. In addition, more than three hundred fifty bird species and three hundred species of fresh and saltwater fish live within the park. The Everglades is also home to forty species of mammals (哺乳动物) and fifty reptile (爬行动物) species. C) Exotic plants can also be found in the Everglades. They include what is said to be the largest growth of mangrove trees in the western half of the world. Gumbo-limbo trees, known for their peeling red skin, strangler figs and royal palms are also among the area’s plant life. The Everglades is also home to the country’s largest living mahogany tree. Sawgrass grows in some areas of the park. Be careful—it is very sharp, with teeth just like a saw. It can grow up to four meters tall. With about one and one-half meters of rainfall each year, plants and trees never stop growing in the Everglades. D) The dry, winter season is the favorite of most visitors, when insects like mosquitoes are less of a problem. The rainy season lasts from June to November. There are many ways to explore the Everglades. Visitors could see American crocodiles while hiking the Anhinga Trail. The Everglades is the only place on Earth where fresh water crocodiles and saltwater crocodiles live in the same area. Visitors using canoes or airboats are likely to see large groups of wading birds like the wood stork or great blue heron. It is even possible to see flamingos in the Everglades. This spring, Everglades National Park launched a visitation program to what was once a highly restricted military base. Park officials are working to recover a missile base used in the 1960s. The base played a Part In the nuclear tensions between the United States and the Soviet Union. E) The government built the Florida base shortly after the discovery of Soviet missiles about three hundred kilometers away, on the island of Cuba. Tensions were high during the Cuban missile crisis. But missiles stored at the American base were never fired. The base was closed and all missile equipment was removed in the 1970s. Today only the buildings remain. This year, the historic area had many visitors, including former American service members who remember the missile crisis. The park hopes to offer more trips next spring, to help support the history for those who lived through it and for future generations. F) Experts say changes to the Everglades are threatening several different kinds of wildlife. They say the threats are a result of actions the United States government began more than fifty years ago, and settlers began even earlier. The National Park Service says early colonial settlers and land developers thought the Everglades had little value. The settlers had plans to remove water from the area and in the 1880s

developers began digging drain canals. At the time, they did not understand the complexity of the Everglades’ ecosystem. As a result, they were not prepared for all the work and caused environmental problems. The ecosystem, however, was able to survive. G) Even larger efforts to drain the wetlands continued between 1905 and 1910. Large areas were changed to farmland. This led to increased development, with more people moving to the Everglades and also more visitors. More changes came in 1948, when Congress approved the Central and South Florida Project. As part of the plan, the Army Corps of Engineers built roads, canals and water-control systems throughout South Florida The aim of the project was to provide water and flood protection for developed areas and agriculture. Workers built a huge system of waterways and pumping stations to control the overflow of Lake Okeechobee, north of the Everglades. Today, fifty percent of south Florida’s early wetland areas no longer exist. Populations of wading birds have been reduced by ninety percent. Whole populations of animals are in danger of disappearing. The endangered creatures include the manatee, the Miami blackhead snake, the wood stork and the Florida panther. H) In recent years, environmental experts have learned about the damage to the Everglades. They say the natural balance of plants and animals has been destroyed. Recently, the Obama administration promised three hundred sixty million dollars to pay for Everglades restoration this year. The administration is also asking that Congress approve an additional two hundred seventy-eight million dollars for next year. The money will help to support projects approved by the government nine years ago. The projects include improving wetlands in the Picayune Strand in Southwest Florida and repairs to Lake Okeechobee’s dam. Until now, the state of Florida has spent the most money on the project. I) Another threat biologists have been battling for years in the Everglades is the area’s population of Burmese pythons (large snakes). Officials believe there are as many as one hundred fifty thousand of these large snakes in the Everglades. But the snakes are a foreign species, native to Southeast Asia Owners of pythons left their unwanted snakes in the Everglades years ago. Biologists say adult pythons are able to eat small deer and bobcats. When pythons are found in the Everglades, they are often killed. Scientists are now experimenting with other ways to remove the snakes, including trapping methods and offering payments to hunters. The future of the Everglades is not clear. However, efforts to protect the area are continuing so that people from all over the world may continue visiting this biological treasure.

Which Attributes of a Food Product are Most Important to Consumers A) The Australian state of Victoria is investing in a program to identify new opportunities for its food and agriculture industries. As part of this initiative the government conducted extensive research to identify which attributes of a food product are most important to consumers. As income levels rise and education levels improve, consumers around the world are becoming interested in more than just the price and quality of the food they eat. Indeed, some consumers are now willing to pay extra money for food with a special nutritional or health benefit. In addition, some consumers are also choosing food based on how it was produced, including the environmental and ethical impact of production. Victoria’s Department of Primary Industries designed and researched a report that analyzes preferences for food products with “trust” attributes, specifically food safety, clean food, green food, animal welfare and ethical food production. The report also determines the relative importance of the five nominated “trust” attributes and evaluates their importance in

relation to non-trust attributes, such as price and quality. B) “Consumers are becoming increasingly insightful when making purchasing decisions, and Victoria’s a-bility to demonstrate the trustworthiness of food products will be vital to maintain consumer confidence in priority export markets,” the report says. Between February and June 2004, the DPI interviewed 280 food industry shareholders, including retailers, wholesalers, foodservice managers, importers, distributors, and representatives of government, industry bodies and non-government organizations, in 21 of Victoria’s major food markets, including France, Japan, the UK and the US. C) The research found, perhaps unsurprisingly, that price, quality and food safety were the most important factors for consumers, with each factor ranked as the most important by 18-22% of respondents. In fourth place, 8% of respondents felt taste flavor was the most important attribute of a food product for consumers, while 6% thought freshness was most important, and 3% thought the appearance packaging was most important. Health nutrition, brand image, and clean chemical free were each considered most important by just 1-2% of interviewees. D) Of the five specified “trust” factors—food safety, clean food, green food, animal welfare and ethical food production—food safety was ranked as being of high or very high importance to their organization by 95% of respondents. It is not just consumers that food safety is important to, as one Japanese wholesaler observed “It has taken a long time to build our reputation for reliability with our customers and just one accident would cause us to lose everything, especially if consumers are harmed.” E) Clean food was ranked second in importance among the specified trust factors, with 90% of respondents rating clean food as being of high or very high importance to their organization. However, just 63% of respondents said clean food was of high or very high importance to consumers. The survey also found that there was regional variation in the definition of clean food—some respondents thought it should include Halal production methods, while others thought clean food should also be free of genetically modified organisms (GMOs). F) Ethics was ranked fairly high in importance to organizations, but was considered less important to consumers. While 82% of respondents rated ethics as being of high or very high importance to their organization, just 31% considered ethics to be of high or very high importance to consumers. Another finding was that ethics included many of the other trust factors, as a German government representative pointed out “This issue covers a little of everything. It depends on the producer and on the way people, animals and the environment are treated. It depends on personal values.” The researchers found that the importance of ethics varied according to what aspect was mentioned. The proving of claims made on product labels was considered to be of higher importance than issues such as workers’ rights, corporate responsibility and local sourcing, because it is an issue that has impact on the consumer directly. G) Green food was ranked relatively low in importance, with just 50% of respondents rating it as being of high or very high importance to their organization, and just 19% rating it as being of high or very high importance to consumers. Many respondents cited low consumer awareness and lack of consumer interest, and some said they believed consumers were unwilling to pay a higher price for green food products, reflecting the overall finding that higher

importance is attached to factors that has impact directly on consumers. H) “Consumers claim to want the choice, but the category has been disappointing, leading to oversup-ply and price pressures for high cost producers. Price always seems to focus the Dutch minds,” said one global retailer based in the Netherlands. There was also some variation in opinions about what exactly constitutes green food, with several respondents seeing it as synonymous with organic production. Of issues associated with green food, organic production was seen as the most important to consumers, while impact on the environment, ecosystem health, bio-diversity and environmental management practices were rated relatively low in importance. I) Animal welfare was another low-rated trust factor, with 43% of respondents rating it as being of high or very high importance to organizations, and just 15% considering it to be of high or very high importance to consumers. Again, respondents pointed to low consumer awareness, lack of consumer interest and an unwillingness to pay an extra cost for “animal friendly” products. Many respondents also said there was a gap between what consumers say and what they do when it comes to purchasing behavior related to animal welfare issues. “This is a complex issue—it is of low importance to consumers in terms of translation into action, but high in terms of a discussion topic. A gap exists between theory and practice,” said a representative of a non-government organization in India. J) However, the importance of animal welfare could be raised if there was a direct impact that can be seen on the consumer, for example where handling or feeding administrations affect product quality or food safety, as an airline catering supplier in Singapore illustrated “Animal welfare is important only in that it contributes to the quality of the product. The way the animal is treated and fed is crucial to the quality of the end product.” K) Overall, respondents identified that consumers are more concerned about factors that affect them directly, such as food safety. Although consumers are considered to be generally less concerned about issues such as animal welfare and environmental management practices, these issues are not insignificant as they assume much greater importance when they have the potential to affect food quality or when public concern is heightened by specific interest groups or media reports. According to Bob Cameron, Victoria’s minister for agriculture, the government’s aim in carrying out such research was to develop new approaches to improve Victoria’s access to international markets. It will be interesting to see how this information is used, and how it influences future product development.
