Marine Debris: Some Definitions Size Meters Navigation hazards Centimeters Entanglement/choking Sub-centimeters Ingestion, invasive species vectors (Microplastics)
Marine Debris: Some Definitions Composition Natural (woody debris) Degradable (paper, cloth) Persistent (plastics, foams, monofilaments)
Marine Debris: Some Definitions Sources At sea vessels Illegal discharge, food grinders ‘lost’ fishing gear Natural disasters Tsunamis, hurricanes, floods Manufacturing Flow injection pellets, machining Abrasives Sand blasting, cleansers, cosmetics

Plastics in the Marine Environment • Plastic packaging generates significant negative externalities, conservatively valued by UNEP at $40 billion and expected to increase with strong volume growth in a business-as-usual scenario. • Each year, at least 8 million tonnes of plastics leak into the ocean. • If no action is taken, this is expected to increase to two per minute by 2030 and four per minute by 2050. • Plastic packaging represents the major share of this leakage.

Plastics in the Marine Environment There are over 150 million tonnes of plastics in the ocean today. In a business-as-usual scenario, the ocean is expected to contain 1 tonne of plastic for every 3 tonnes of fish by 2025, and by 2050, more plastics than fish (by weight).

Solving the Problem: At Sea Clean-up?
Solving the Problem: Breaking the Supply Chain Enhanced recycling/reuse Degradable polymers Education But in the meantime….
Solving the Problem: Breaking the Supply Chain The largest source of marine debris is most likely litter and other types of improper disposal along coastlines, rivers and harbors.
Marine Microplastics Supply Chain Disintegration Dispersal Accumulation
