Group Work
• What might happen to Antarctica if
there were not the Antarctic treaty to
protect it?
• If there weren't the treaty, Antarctica
would be in disaster.
The reasons are as follows:
• Firstly, there might be excessive(过度的,过
分的) commercial and military use of it，
causing animals and plants to die.
• Secondly, it might be polluted by nuclear
tests or radioactive waste badly, which
can leave ecosystem out of balance.
• Finally, the arguments about who owns
the land might cause another world war.
Owing to the treaty, Antarctica
has become perhaps the most
successful symbol of man’s
efforts to work together for
progress and peace.
