Script:

Ava:What are you doing, Matt?

Matt:Hi, Ava. Having planned a summer holiday in Hawaii, I’m learning a few basic Hawaiian phrases.

Ava:I don't think this is the ideal time to visit Hawaii.

Matt:Why not?

Ava:Having suffered from over-tourism, the locals are asking tourists to stop visiting the island. Thousands of new arrivals every day are creating traffic jams, overcrowding and resource depletion; and the local people have to cope with their consequences every day.

Matt:Actually, I have heard of the problem but I try to be responsible whenever I travel. I'm aware of the impact on the environment and the local community. Therefore, I usually shop locally to help the community's economy. When possible, I always book eco-tours.

Ava:Not every tourist shares your sense of responsibility. Some use natural heritage sites as a backdrop for their pictures and display disrespectful behaviour towards other countries' cultural heritage. In some cases, tourists even destroyed natural and cultural landmarks.

Matt:Some tourists can misbehave; however, I think tourism, in general, can be beneficial. It was the financial gain from tourism that contributed to many projects that preserved and protected heritage values. Having received more job opportunities, local people also benefit from the popularity of tourism.

What does Matt usually do when he travels? A. He buys some stuff from local people. B. He fulfils his responsibility before departing. C. He books the cheapest tour.
