If you are a teacher or concerned community member and are looking for a novel way to raise awareness of ocean debris in your school or community, this might be the right time to start an ocean rubbish string ball as suggested by SOAR here. A collection of string balls might make a terrific focal point for a conversation/communication piece on ocean pollution.
If you are suggesting this activity to students, in particular, safety is very important! Debris may have sharp bits on them or under them and hands must be washed after touching things from the beach.
Teachers looking for a unit on Marine Pollution to bring the point home are welcome to use the free online materials provided by AUSMEPA here.
