ON ETHICS: Look at PengAtlas Map 4.1 and the current trade routes. Although current routes do not go through the Arctic Ocean, global warming has made some shipping possible there for limited periods. Also, some farming is returning to Arctic areas such as Greenland. Given the area’s natural resources, emerging agriculture, and potential new trade routes, make a case for how potential problems, such as fl ooding in port cities, may be at least partially offset with potential benefi ts from higher temperatures in the Arctic and Arctic Ocean.
