Marine litter is a big problem, and it requires big solutions. Solutions begin with awareness — awareness on the issue and awareness that leads to action. The Marine Litter Learning Kit: A Facilitator’s Guide (“Marine Litter Learning Kit”) is designed for educators and facilitators who organize environmental education programs that focus on marine litter. It is meant to be applicable to various learner profiles and learning situations where facilitators can choose the activities appropriate for their target audience. It also uses the learning-by doing approach, providing hands-on activities and games for learners.
