I am appreciating the coverage of IUCN by Civil Beat. 
    WE ARE residents of the "some nations" that  just don't understand that plastics should not be disposed of in the ocean  - right here in Hawai'i nei.  If you have ever participated in a beach clean-up you know this too well; and when waves wash over the highway you see  it is littered with plastic junk and recyclable bottles.  What more can we do since education doesn't seem to work?  
    What can you do to the perpetrator when you see them abandon a bottle or a poopy  diaper in the naupaka at the beach?   Photo them and get them fined?
 How much is a fine like that? Apparently not enough to be a deterrent.
  What else can we do? For plastic bottles, making the deposit and return fees MUCH higher MIGHT incentivize some. Could we authorize bounty hunters?! I am obviously disgusted by the thought of "more plastic than fish in the ocean by 2050" ...
