The following is a roundup of some of the latest scientific knowledge on marine litter and ocean plastics. It is based in part on a longer, more detailed article from November 2017 by MPA News’ affiliated service Marine Ecosystems and Management (MEAM).

If you are interested in this topic, please note that OCTO – the organization that produces MPA News and MEAM – also runs the global discussion list on marine litter and ocean plastics: MarineDebris.Info. It is a thriving community. In April 2018, for example, there were over 170 member posts to the list. To subscribe to the MarineDebris.Info email discussion list, click here.

The effective management of MPA networks requires an array of elements. These include having adequate technical capacity of site managers, good science, committed leadership at multiple levels (sites, agencies, and policy makers), shared goals among MPAs, and monitoring of the network’s ecological effectiveness.

Importantly, it also requires good connectivity among site managers – in other words, a social network.

Volcano fills in MPA with lava
