It is becoming clear that there is a fair amount of small plastic distributed in the oceans and on beaches worldwide, not surprising given its durability and floatability. Marine debris is often ingested by animals such as sea turtles, marine mammals, and seabirds. Items such as lighters and small plastic pieces may look like food to an animal, or have an animal's natural food attached to it. Debris may also be ingested accidentally with actual food items. Exactly how many of them die each year due to marine debris ingestion is not
known.

The main purpose of SEM-Pasifika is to improve site management of the coastal and marine areas in the Pacific region. It should guide interested communities in the region (including communities who have used existing methods and new communities without experiences in socio-economic assessment), management and project staff, researchers, and other practitioners, to understand important steps involved in a socioeconomic assessment and to be able to conduct the monitoring.
