A recent study has revealed an alarming growth of plastic fragments in the so-called North Pacific Garbage Patch . This region, known for its high concentration of marine debris, now has critical levels of microplastics that outnumber larger particles.
Study reveals growing threat from Garbage Patch
Led by The Ocean Cleanup, the research analyzed data collected between 2015 and 2022. The findings showed an exponential increase in the concentration of small plastic fragments, which have grown from 2.9 to 14.2 kilograms per square kilometer in seven years . Surprisingly, most of these fragments appear to originate from plastics discarded decades ago in various parts of the world.
The effects of this accumulation are profound. The presence of microplastics affects zooplankton, a critical link in the marine food chain, and could alter the global carbon cycle. In addition, invasive species have found refuge in floating debris, competing with local species and upsetting the balance of the ecosystem.
Scientists stress the urgency of international action to address this crisis. Laurent Lebreton, lead author of the study, stresses that “ the incessant accumulation of plastics is a direct consequence of poor waste management” . Stopping plastic pollution and removing existing waste are essential steps to protect the oceans.
The study reaffirms the need for coordinated policies and shared responsibility to mitigate this growing threat to marine life and the planet.
