Is geography important? Here's a question for you to answer.
What have the following countries got in common: Australia, Japan, the United Kingdom, Iceland and Madagascar?
Quite easy if you can picture them on the globe — they are all islands. All of these nations are surrounded by sea.
What have these five nations got in common? Hungary, Botswana, Kazakhstan, Paraguay and Liechtenstein. They are all landlocked. In other words, in contrast to the first five countries whose coastline forms their border, the second five have no coastline at all. If you are a Hungarian or a Paraguayan, you have to pass through somebody else's country if you want to go to the beach.
