A few days ago I went to check if a beach clean up would be necessary. Looked clean. Today I thought about the Ocean Initiatives and the beach clean ups I used to do and went to the beach. 7 black plastic bags, some transparent plastic sheets, a wine bottle, an orange toy shovel.
Usually packaging shows German text, most trash is homemade. You will find Cyrillic letters - Russia is not so far away. Sometimes south Asian letters - ship crew members are often from there.
