Thinking about the Earth...and its many parts

There are many ways to divide up the planet geographically into conceptually digestible chunks. At a large scale, it's commonly done by continent or by region, but each of these can be done multiple ways (yes, even continents, for which 5, 6 or 7 can be the "correct" answer to "how many?"). What you see here will likely change over time as this portion of grows. In the meantime, the careful observer will note some gaping holes in the coverage here...this is very much a work scheduled to be in progress....

Topic-specific vs. place-specific information

If, say, you are interested in the topic of “freshwater in Canada,” there are at least three possible pages on that might provide relevant information:

(1) The Canada country page, which has a section on freshwater;

(2) the North America page, which also has a section on freshwater, some of which might be relevant to Vietnam; and

(3) the Freshwater hub page, which links to various pages on freshwater; while these are less likely to have anything specific to Canada, they might nonetheless contain useful resources.
