RESUMO
Societal change is needed to prevent and reduce the growth in the amount of solid waste entering the sea. Marine debris networks cover a broad range of activities in order to protect our oceans. By following a common vision and a collective systematic approach they are capable of creating synergies between all relevant stakeholders that result in reducing the flow of waste into our oceans. Thus, they are key to achieving the Sustainable Development Goals. During the 6th International Marine Debris Conference in San Diego in 2018, different marine debris networks from different parts of the world presented their activities, achievements and challenges. This led to network representatives agreeing to collaborate as members of an International Waste Platform. This platform aims to harmonize objectives, share knowledge, join forces and help new networks to emerge.
