eracode said, "I didn't realise Luxembourg and Switzerland used to have a coastline." and loydbloke said, "I didn't realise Belgium's coastline had been removed."
They will get a coastline back with global warming.
If lower drown rates is due to lack of coastline, then WSNZ should remove our one to save the nation... logically.
Belgium has only just enough coast for a few people to go for a swim.
I can't find statistics specifically related to seaside drownings, but in 2019 (most recent) there were altogether 54 (fatal) drownings in Belgium according to Statista.com. This compares to 82 drownings in New Zealand according to the WSNZ Drowning Report for that year. Considering the differences in land, population and coastline area, it doesn't look like the amount of seaside is particularly relevant here.
