One If By Land, 31 If By Sea

Some math to do on your fingers (but first some news):

NEWS FLASH - Thirty-one North Koreans arrive in South Korea after crossing the Yellow Sea by boat.

(Recently, I don't know when - reference: Yonhap News)

If we could just get this to happen once a day, NoKor could be completely empty in the year 4135 on April 2nd at 5:41 PM

(Why, of course I used a spreadsheet! You would not have expected inaccuracy from me, right?)

Of course this math assumes very exact birth control. I tend to think of NoKor as a form of birth control all by itself.

Supposedly that Apr 2nd day in the far far distant future is a Saturday. That would be a fitting nice way to end a work week, the closing down of NoKor. 

It could become a forest, maybe?
