Being Dutch living in one of those barely visible dark blue stretches of below sea level literal low-lands makes one rather aware of our precarious national position as far as rising sea levels are concerned.
The east coast of the US, Florida, and the Gulf coast are totally hosed though.
Ah that ought to do it.
If there's one country that has had long experience in dealing with the threat from the oceans, it's the Netherlands. And these kinds of projects don't really lend themselves to organizations that require profit for their investments.
(I'm not dutch, but I have biked across the 32 km long causeway of Afsluitdijk[4] and parts of the Delta Works.)
