@ Peter
The standard procedure nowadays,,finger pointing to ships !!!.. I make since years pictures of dirt in ports,, like plastic/waste/dead animals etc etc
one day I will publish them. But it is much easier to point fingers to a foreign ship then to point to the own population to keep the country clean or "god beware" require that from tourists,, much more easier: bad bad sailors,, no lobby and no help
and put one to jail for a while for a enviromental misshap is the best for authorities to show how tough they are on enviromental regulations,, only not for themselves !!
For example,,the houston Ship channel is called for a reason the Houston SHIT Channel or
the Ghent canal,, once you are alongside,,within hrs the space between pier and ship is full plastic and whatever,,but that,s normal,,then moment a sailor throws a cigarette butt into the water,,the authorities getting active !!!!
A joke all over the world by now
