"Most of the world’s population lives and works not far from the ocean"
Let's see - so that's India, Indonesia, China, Brazil & the USA,,, with Nigeria coming up fast...........
which one are we going to fight first???
Actually something like 90% of the world's population lives within 100 miles of a coast line. I can't quote the reference, and it's certainly not an accurate figure, but the proportion is very surprisingly large.
