The 131 onshore and 35 underwater clean-ups took place across the country, between 19 and 27 September, and involved more than 170 organisations during 400 hours of work along 187 kilometres of coastline, river banks and the seabed.
The initiative brought together diving centres and schools, with the participation of 400 divers, the organisation said in a statement.
The Oceano Azul Foundation welcomed the support of all the organisations and volunteers for the initiative, considering that it gave “clear signs of the growing mobilisation of society to combat one of the greatest threats to the ocean”, marine debris.
