The author of the passage argues that although the climate is extreme, the current technological development make it possible like in Alaska and North Sea, and it would provide a very good quality resources. On the other hand, the professor on the lecture thinks that this installations would be more expensive and difficult than the ones in Alaska and North Sea.
Other important point on the argue is the fact that Antarctica is practically unpopulated except for the coastal areas. On the passage, the author explains that it is an advantage because there is an enormous area to extract fossil fuels without danger for people. However, the ecology class’ professor thinks that the species that live at coastal zones are very fragile and would be in danger.
