How Plastics End Up in the Ocean

Studies have found that 80% of the plastics are land-based. Plastics from landfill enter into the ocean through poor management and improper disposal of sewages and plastic wastes, costal landfill operations and litter carried through streams and rivers. Other sources include accidental spillage during handling and other processes. The remaining 20% are the litters generated by ships/boats through recreational activities, discharge of marine litters 9, nautical activities, fishing activities and aquaculture. Of which commercial fishing accounts for most of the impacts. This includes discarded fishing items, together with monofilament liens and nylon netting.

Due to their buoyancy, plastics travel long distances by wind, tides, and currents—reaching even remote islands and deep-sea areas. Events like floods and hurricanes further push land-based debris into the sea. Ocean currents gather these plastics into vast “garbage patches”.
