Ship tourism to Antarctica is on the rise:More than 35,000 tourists are expected to visit Antarctica this summer. In 1992－1993, 6,750 tourists visited Antarctica,according to the Antarctica Treaty. All of this tourism, however, is putting both tourists and the environment ingreat danger.

Among the tourist ships that visit the continent, the Explorer, a Canadian ship, was one of the first.Put to use in 1969, it was built to carry tourists to Antarctica. Last week, however, it became the first commercial (商业) passenger ship to sink beneath the waters. Fortunately, all of the passengers and crew members were rescued from the ship. However, the sunken ship endangered the Antarctic's fragile (脆弱的) environment. The ship was estimated to be holding 48,000 gallons of fuel.

As a natural frontier, Antarctica is in a messy legal situation. There are no obvious answers as towho is responsible for dealing with the threat that tourist

Antarctica：the Last Continent

①

Antarctica is the coldest place on Earth. It's also the driest. With annualrainfall close to zero， Antarctica is technically a desert. Covering about 14 million square kilometres around the South Pole， it is the fifth largest continent in the world. A high mountain range, the Trans-Antarctic range， runs from east to west, cutting the continent in two. There are volcanoes too, but they are not very active. Antarctica holds 90% of the world's ice, and most of its fresh water (70%) is in a frozen state， of course. 98% of the surface is covered permanently in the ice cap. On average it is two kilometres thick, but in some places it reaches adepth of five kilometres. Strong windsdriven by gravity blow from the pole to the coastline, while other winds blow round the coast. It is difficult to imagine a more inhospitable place.
