But that's the point, isn't it? In the general sense, one stuck container ship in the world shouldn't have any impact on "us," except for the people whose "stuff" is on it.
That sounds a bit too self-centered a viewpoint in that it is far too narrow and ignoring that there are knock on effects to everything in a general sense that while they fade into the ambient still have an impact. You may not notice say a banana blight in Ecuador and might ask "whatever what does that even mean to me"? Then you wonder why bananas went up fifty cents a piece.
