It is, again, easy to appreciate that economic activity has a geographic component. Resources are only found in certain places and must move to other places for production. Farmland is not of the same quality everywhere. Some parts of the world are manufacturing centers, others are farmland. Some have no seeming value.
Some places are poor and some are rich.
The study of all of these, and a host of other questions, is economic geography. Considering teaching high school geography, we want to make sure that students realize that this exists. In North Dakota telling local kids that factory jobs are not that plentiful here and the farming is more important here than elsewhere should be easy. Understanding that economic geography varies in space. Understanding the global nature of the economy, including the role of multinational corporations.
