Upon invitation, a representative of NOWPAP delivered a lecture on marine litter at the Toyama Prefectural University on 26 June 2015. Targeting a group of university students, the one hour lecture started with stressing the global threat of marine litter and then introducing the efforts against marine litter at both global and regional levels, including cooperation among NOWPAP members through the implementation of NOWPAP Regional Action Plan on Marine Litter. The lecture will help students understand the issue of marine litter and relevant actions undertaken both in Japan and internationally.
