1. What do you know about Antarctica? Read the fact file. Which piece(s) of information do you find most impressive?
All About Antarctica
• It is the coldest, windiest, highest & driest place in the world.
• It is approximately 48 times the size of the UK and twice as big as Australia.
• It has over 90% of the world’s ice & 70% of its fresh water.
• In some places, its ice is over 3 km thick.
• It has not rained in the ‘dry valleys’ region of Antarctica for at least 2 million years.
• The lowest temperature ever recorded in Antarctica was -89.2° C.
• Some of the fish around Antarctica have proteins in their bodies which stop their blood from freezing.
2. Check the collocations in the Word List. How could these things be related to Antarctica? Read the text to find out.

The Challenge of Antarctica
The Earth’s Last Great Wilderness
A hundred years ago, the great explorers Scott, Shackleton and Amundsen were racing to be the first to reach the South Pole. Today, the beautiful frozen
continent o f Antarctica is facing some very different challenges ...
Global Warming
Global warming is nothing new. We all know that burning fossil fuels, greenhouse gases and deforestation are 1) meaning/causing/putting/effecting world temperatures to rise. But 2) to/from/about/over the past 50 years, Antarctica’s temperatures have increased by about 3°C, around 10 times more than the rest of the world! As a result, glaciers and sea ice are melting and ice shelves are breaking off into the sea, which is very bad news! If Antarctica’s thick, polar ice sheet 3) eventually/lastly/lately/truly melts, not only will the world heat up generally, but global sea levels could rise by about 6 metres, flooding many coastal areas. This is extremely worrying, as almost every city with over 10 million people is 4) at/on/about/around the coast!
Another problem is that melting ice forms clouds, which 5) directs/leads/follows/results to more snowfall. This can make life very difficult for some of the wildlife in Antarctica, such as penguins, whose eggs rot in the snow. Scientists are also worrying about rising sea temperatures. In seas just 2°C warmer, mollusks cannot bury themselves in the seabed, limpets cannot turn over and scallops can’t swim. These creatures are then caught more easily by predators and the 6) whole/total/big/full food chain is affected. It won’t be long, therefore, before larger birds and animals such as whales, seals and sealions are endangered if sea temperatures continue to rise!
Human Impact
Antarctica isn’t called “the Earth’s last great wilderness” for no 7) intention/cause/opinion/reason! No country owns it and no native people live there. Therefore, its clean air, water and ice make it the perfect place for scientists to 8) carry/put/bring/have out research. Therefore, Antarctica has become the world’s largest laboratory! Many countries have 9)set down/make up/set up/put down scientific bases there, which means that the population now ranges from about 1,000 in winter to about 4,000 in summer. Also, 30,000 adventurous tourists now visit Antarctica each year. It might seem like a nice idea to visit a totally unspoilt place full of amazing scenery, wildlife, glaciers and icebergs, but wherever there are humans, there is impact on the environment such as rubbish, C0₂ emissions from burning fuel and pollution from boats. If we are not careful, both scientists and tourists may 10) break/kill/injure/destroy the very qualities that draw them to Antarctica!
3. Read again and choose the correct word for each gap (1-10). Listen and check.
4. Explain the underlined words/phrases. Check in the Word List, then use some of them to complete the sentences below.
The world's rainforests could completely vanish in one hundred years because of ..... .
2 Sea turtles lay their eggs on the beach, then ..... them in the sand.
3 The river burst its banks, ..... the nearby village.
4 Seals are often caught and eaten by ..... such as sharks, whales and polar bears!
5 The temperature in Antarctica ..... from about -70° C to -20° C.
5. Why is it important for us to protect Antarctica? How can we do this? Spend three minutes writing a few sentences on the topic. Read them to the class.
