The fact that Canada is not on the list with 90% of its territory hosting no humans while many more densely populated African countries make it is very indicative of the different impact they have

Yet not at all surprising. Every country on this list is poor or developing.

So that's why they call it the Dark Continent.

Tricky-ish. I just got all the African countries and DPRK. I did try a few Oceanian countries, but after none of them hit I decided they were probably all off limits.

The other two were both total surprises for me.

I did the same except I got Mongolia. Not sure about Guyana but Mongolia's on there because it's the sparsest country in the world.

Very difficult until you figure out that most of them are in Africa!

And Algeria, with no one living in 95%+ of the land area (Sahara), isn't on here?

Nice quiz. Minor issue, but the description should end with a question mark.

Some interesting answers there - it was hard to think of enough countries outside Africa. Might help to clarify what is meant by "entire territory " if a country as i started thinking about Greenland as part of Denmark.

The descriptor says "over the entire territory of the country." If that's true, all the small island states with multiple islands (think Marshall Islands, rather than Barbados) should be here. Even if it's only land area, it's really hard to understand Tuvalu's high position on this ranking relative to other similar states.

Chad is a shocker considering its one of the most air polluted countries in the world.
