nature reserve. The aim of the treaty is to prevent the com
cial and mlilitary use of the continent.
Para 4.
Then in 1895, a Norwegian called Carstens Bdchgievink
became the first man to set foot on the Antarctic mainland. The
race to the pole had begun. It was fianlly reached on 11th
December, 1911 by the ...
Since then another 32 countries have signed the treaty.
Over the next 15 years a number of unsuccessful journeys to the
pole were made by explorers such as Emest Shackleton and
Robert Scott.
Para 1
... 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 a depth of five kilometre. Strong winds driven by

If the ice melted, the sea level would rise by about 60 metres.
Some have come from the Moon and Mars.
Para 2
Yet Antarctica is full of wildlife, which has adapted to its
extreme conditions. There are different types of penguins,
flying birds, seals, and whales. But the long Antarctic
winter night, which lasts for 182 days (the longest period,
of continous darkness on earth), as well as the extreme
cold and lack of rainfall, means that few types of plants
can survive there.
Most animals survive thanks to their fat, which protects them from the
cold.
Task 3 Practice 1:
Each year thousands of tourists visit the polar regions of the Arctic and
Antarctica. __1. __ But the increasing number of people travelling to the ends of
the Earth can have an negative effect on fragile ecosystems. ___2.___
About 40, 000 tourists visit Antarctica each year. __3.__ Transporting tourists
to the regions increases ship and airplane traffic, and adds to the risk of pollution,
oil spills, and other environmental damage. Because the places where wildlife is
accessible are few in number, tourist traffic can become concentrated in specific
areas. __4.__ Recreational activities such as boating, fishing, and skiing can also
cause disturbances to animal colonies.
Some people say that access to these very special parts of the world should
not be restricted to only researchers and scientists. __5.__ “Those who travel to
the Arctic or Antarctica often become cheerleaders for supporting those places,”
Jim Sano, vice president for travel and conservation at World Wildlife Fund, told
TFK.”
