Landmines can pose a threat to both military and civilians even decades after fighting has already stopped. Can you name the countries with the highest amount of landmine contamination?
Typically, I think of percentage when I hear contamination. Perhaps "Countries with the Most Landmines" would be a more relevant title? Also, I recommend changing the caveat to just "Figures are estimated", but not a big problem there. Other than some minor details, great quiz!
