If you went to Seychelles, you would expecta) To shop for elegant and expensive merchandise at discount pricesb) To get a great tan from spending your time at the beachc) To be completely comfortable and cared for while seeing the sightsd) To tramp through muddy spots and get sweaty and dusty17. The government of Seychelles values which of these most highly?a) Attracting tourists with lots of money to spendb) Providing jobs and income for the peoplec) Protecting the natural beauty of the islandsd) Remaining crime-free and safe for visitors.18. Among the activities that generate income for the islands from tourism are all of these excepta) Hiring a carb) Taking a package tourc) Visiting other islandsd) Eating in a restaurant19. Based on the passage you could state thata) Seychelles was able to avoid mistakes when planning for touristsb) Conservation is less important now than beforec) Seychelles wants more tour groups to visitd) Green tourism is still too damaging to natural beauties.Nobody visited the Seychelles much until 1971 when Male airport was opened and the world could flood in. Now more than half the country’s foreign exchange earnings come from tourism. This is an industry which could, if not manage properly, destroy the environment. Coming fairly late into the tourism business means that the painful lessons of the older world have been well studied in the Seychelles. The beauty and unspoilt nature of the islands are carefully protected. No Seychelles hotel is allowed to rise above the surrounding palm trees and none may get rid of waste into the sea. Patrols clean the beaches daily and the sea is constantly monitored for signs of pollution which, when detected, are quickly deal with. After a brief period of package holidays and mass tourism, the current policy is to attract the ‘ quality visitor’.Because the amount of visitors must be limited to protect the environment, the quality of the tourist matters a great deal. Lindsay Chong Seng, a highly committed conservationist in the Ministry of Tourist, considers the economics extremely important: you have to earn as much as you can from each tourist if numbers are to be kept down. ‘A perfect tourist is active , hires a car, flies to other islands , takes boat trips, eats out, goes diving spends money. We don’t just want to be a beach resort. When you get mass tourists without a lot of spending money, all you find is that the shops do no business and the local bus service is overcrowded. This has been the fate of all too many tourist resorts in the Mediterranean, with disastrous consequences.’Quality visitors are also those who come mainly to appreciate and enjoy the Seychelles’ natural beauty. This can sometimes mean discomfort. Atterville Ceydras, the nature warden on one of the islands, says that tourists have got to accept nature. ‘If it rains, that’s nature, that’s good. If the wind blows seaweed up on the beaches, that’s nature. They say they come to see nature, they’ve got to put up with it.’Not all do so. The international travel business has over the last twenty years, made the mistake of letting the Seychelles be sold in Europe as a ‘holiday paradise’ and, in so doing, they miss the point.Tourists are now going who should probably not bother- like ladies in elegant shoes who will not follow muddy walkways through wetland nature reserves; or the man in the glass-bottomed boat who, looking at the fish city beneath him, could only ask if the fish could be eaten or not. Many others, more inclined for adventure and safari and the wonders of the world do not go. There are plenty of other more exotic , more exciting destinations. Probably some rich, green-minded Westerners avoid Seychelles because of a guilty feeling that tourism spoils such places. But in this case tourism need not, and poverty surely would.
