The beautiful Seto Inland Sea has large amounts of plastic trash washing onto its shores which have been neglected for decades. There are more than 500 of those trash-strewn beaches in Ehime Prefecture alone. Most of these places go unnoticed since they cannot be seen from land, but if we continue to neglect this, the plastic will turn into microplastics which will impact marine organisms. I would like to tackle this marine debris issue and report widely on how urgent it is.
