think plastic isn't a problem, consider this link below which only highlights one small part of where it goes and what it does, especially how it gets there;

Come for the beaches, say tourism ads for the Dominican Republic.

But it has some beaches you might want to skip right now.

The Caribbean nation is known for sapphire seas and ivory beaches, but it is grappling with waves of garbage washing up on its shores, a vivid reminder of the presence of thousands of tons of plastic in the world’s oceans.  

Those piles, most notably the “Great Pacific Garbage Patch,” are usually far from human settlements, to say nothing of resort destinations.

But instead of visitors relaxing on Montesinos Beach in the capital, Santo Domingo, there has been an altogether different scene, one unlikely to wind up on a postcard: Hundreds of city workers and volunteers who have been waging an uphill battle against wave after wave of sludgy garbage.

Images have shown teams using pikes, shovels and excavators to lift the garbage, only to be met with new waves carrying even more.
