Who would have thought that a country could change so much in a few thousand years, and for the better? Of course, infrastructure and the like would easily change, however, you probably didn't think that the land mass itself of a country would change. However, that is exactly what happened in the Netherlands. You can see on this map the difference in the shape of the country from the 1300s to today.
The real question now is how did they manage to do that? It seems like it is going against everything that would happen naturally in the world.
