I wont rant about human behavior, just record the stupidity and let everyone make their own opinion.
This thing floats and can easily be removed from the water. What do we do with things that sink?
International Coastal Cleanups are by far and wide not sufficient, let alone severely limited by the depths - those of the seas and those of the human stupidity!
What do we do, then? Change the human mind perhaps? Mission impossible...
There actually are ways to better things, but stupidity (which seems to be far more powerful than anything), has made sure ages ago that all efficient ways are - illegal.
