Many young people all over the world love to travel and see the world. Have you heard of backpackers? They are normally young people who travel cheaply with just one bag and comfortable walking boots. They buy local food in supermarkets to save money and at the same time become friends with local people.
Some people prefer adventure tours. Brave people may try bungee(蹦极) jumping from the bridge overlooking the Victoria Falls in Africa with only a rope around their legs. Some enjoy the challenge of rock climbing in the Alps in Switzerland. Others may go ice skiing in the Rocky Mountains in the USA.
Have you ever heard of an ecotourism (生态旅游)? It means a holiday in which people come close to nature but are very careful not to destroy the nature beauty or living things in the area. How can this be possible? Let's read an interview with people who enjoyed a swimming with dolphins tour.
Interviewer what was the most exciting part of your holiday?
Sharon from South Africa I felt excited when I heard the sound of wild dolphins beside me in the water and then swimming directly under me. An image I will never forget.
Xavier from Portugal There were two dolphins below us swimming downwards. One stopped and looked back at me as if to say “What are those strange things?” Fantastic!
Interviewer Did you feel that your holiday helped local people and areas to keep their beautiful environment?
Jane from New Zealand The hotel and the whale and dolphin watching companies hire local people. They used to hunt those whales and dolphins, but now they can earn money from tourism and mustn’t kill whales and dolphins. Not many boats are used at the same time so these animals aren't disturbed. The boat companies also work to educate the local schools about the importance of protecting these wonderful animals.
Helen from England I am glad they are not killing the whales and dolphins any more, but the cars and boats use fuel(燃料) which could cause pollution and make the sea dirtier.
Well, what do you think? Thousands of people visit the Forbidden City or the Great Wall of China every year. Do you think that's a good thing, or do you feel that China's important tourist attractions can be affected? Are there any ways of sharing your treasures (珍宝) but keeping them in good condition?
