Can you tell us something about the history of the Westfriese omringdyke?
The dyke is almost 800 year old. It’s
built out of several layers. The height
of the dyke has been raised every
10 years with a new layer.

What will happen to Holland if we won’t do anything about the situation, in case of global warming?
Most of the country is below sea level.
If we don’t do anything, the water would overflow the country and it will disappear, as in
1953.
