This summer's home migration has left its mark - in the form of increased litter.
In any case, this is the opinion of the organizations Städa Sverige and Pantamera, which for the tenth year in a row have arranged a cleaning day for youth associations all over Sweden.
One of the associations that has gone out this year is Karlskrona Dinghy Club, which has found everything from old bicycles, to mossy backpacks and hammers on the shores around northern Långö and at Studentviken.
Hear the young people talk about what they found in the clip above.
