Unfortunately, most of the relevant information on Denmark's natural resources was in Danish (well, I think it was in Danish). The most I could gather was that Denmark mines petroleum and natural gas, and it also has inorganic resources such as salt, limestone, stone, gravel and sand. They do have fish (of course) in the ocean waters surrounding the country, and these fish are caught for both commercial and recreational reasons. The country also has some forest and woodland, but the uses are unknown.
