The Source of Microplastics is Plastic Scattered on Seashores and Riverbanks How to Reduce Ocean Plastic Debris by a Former River Cleaning Worker

It has been 10 years since published "Plastic waste inputs from land into the ocean" in Science in 2015, and this paper has led to many research articles on ocean plastic debiris being published worldwide [1]. However, from my experience working in river surface cleaning, I have noticed that there are many articles that do not fully understand the dynamics of them. In this paper, I show that Jambeck et.al.'s predictions about them are nearly twice as high, that the article by, which claims that a large amount of plastic waste, which is a reserve of microplastics, is remaining on seashores and riverbeds, is closer to the reality, and that most missing plastics are scattered there [2]. As a solution to this problem, I propose the establishment of specialized cleaning services for seashores and riverbanks, the installation of automatic garbage collectors that automatically pick up plastic waste flowing out of rivers, and the obligation for citizens around the world to clean up once a year.
