Just a few scientists in research stations share the icy landscape with penguins and other animals which can cope with the low temperatures. Tourism began in Antarctica in

55、 the 1950s and it's still a small scale. About 37,000 tourists are expected there this season, but many won't even leave the boat. The BBC's Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour

56、guide admitted that all visitors leave footprints and they all go to the same place, the accessible coastline, which is also where the penguins and seals go to breed.
