My analysis of that analogy is that "ocean," being on both sides of the equation, simply cancels out, so basically it is saying that a 3000 shipping containers equals one drop. Which I'm not buying. :)

There are five oceans worldwide, though. So I would like to correct your calculation like this:

3000 containers/(1 year * 5 oceans) = 1 drop/ocean

Therefore 1 drop equals 600 containers/year.

Have a nice day and stay silly :)
