M: Hello, I’m Rob. Welcome to today’s program. With me in the studio is Linda. Hello, Linda.
   W: Hello, Rob.
   M: And in this program we’re talking about tourism, but in a very special place: Antarctica. It is considered the last great wilderness on Earth.
   W: Yes, in Antarctica there are only research stations with scientists and a few tourists.
   M: Not so few — about 37, 000 tourists are expected there this season. Many don’t go ashore but there’s no denying that it disturbs the environment.
   W: That many?
   M: Yes. We’re asking if it is fair for tourists to go to such a sensitive environment. Linda, do you know a lot about the South Pole?
   W: I’ve been reading that the ice caps, those thick layers of ice permanently covering a vast area of land in the Arctic and Antarctic, are melting due to global warming...
   M: Yes.
   W: You know what, Rob? I would like to visit Antarctica before it melts too much. I want to see the penguins. They are very amusing animals!
   M: They are, yes. Well, I love travelling but I wonder how that very sensitive environment in Antarctica is going to be preserved. We’re all too aware that this is not our habitat. Like a scuba diver under the sea we’re alien visitors in the penguins’ world, which makes us wonder: should we be there at all? Are we just by setting foot on this extraordinary continent polluting the last great wilderness on Earth? All visitors leave a footprint, and we all go to the same places, the accessible coastline, which is also where the penguins and seals go to breed. Nonetheless, some believe carefully controlled tourism is not just okay but useful. Without a native population of its own, Antarctica needs advocates. And tourism creates a global constituency of people who are ready to support and indeed fund its preservation. Not everyone is convinced that the benefits outweigh the risks, but most are pragmatic.
   W: Some people might not agree because if there are some companies making profit, it might be difficult to prevent an increase in tourism to Antarctica. And what control do they have over the tourists?
   M: They’re given a mandatory briefing before gathering for a "vacuum party". They bio-secure themselves, hovering their clothes and kit and disinfecting their boots to ensure they introduce no alien species to Antarctica. There’s no eating or smoking on land, and they’re instructed to take nothing away, except photographs, and leave nothing behind. Not even a bit of yellow snow. So, don’t drink too much at breakfast.
   W: But what do you think about visiting Antarctica, Rob? Are you keen on paying the penguins a visit?
   M: Absolutely, I would love to go there. What about you, Linda?
   W: Yeah. I’d like to go because as I said, it’s all about the penguins.
   M: Well, that’s it for today. Goodbye!
   W: Bye!
