At the top of the world, under the ice, lies a large number of natural resources. Gas, coal, uranium and other minerals, even diamonds, sit under the ice inside the Arctic Circle. As climate change pushes the cold and ice farther north each year, discussion increases about how to get to those resources. Less ice also means possible new business in shipping, tourism and fishing. But, industry experts, researchers and people in the far north say there are many problems in reaching those rich resources. People who want to protect the environment are against any large effort to take Arctic resources. They warn that the fragile environment could be harmed past repair.
