A new study published in Nature reveals the alarming extent of microplastic pollution in the world's oceans. Researchers analyzed over 1,800 measurement points across various depths, finding microplastics even in the deepest layers. These tiny plastic particles interfere with natural carbon storage processes, potentially destabilizing Earth's climate.
At 30 meters depth, only 0.1% of floating particles are plastic, but this rises to 5% at 2,000 meters. This contamination disrupts the delicate balance of organic material that normally transports CO2 to the ocean floor—a critical mechanism for climate regulation.
The study calls for standardized measurement methods and international cooperation to address this growing environmental threat.
