Overview
In March 2018, a major study revealed the Great Pacific Garbage Patch was 16x larger than previously estimated — covering 617,763 square miles (larger than France, Germany, and Spain combined) between California and Hawaii. #GreatPacificGarbagePatch raised awareness of ocean plastic’s staggering scale.
Significance
The patch contains 1.8 trillion pieces of plastic weighing 80,000 tons — equivalent to 500 jumbo jets. Contrary to popular belief, it’s not a solid island but a soup of microplastics, with concentrations of 10-100x higher than surrounding waters. 46% of the patch is abandoned fishing nets (“ghost nets”) that continue killing marine life.
Microplastic Crisis
Large plastic breaks down into tiny particles that marine animals ingest, entering the food chain. Microplastics were found in fish, seabirds, and even human blood and lungs. The patch represents less than 1% of ocean plastic — most sinks to the seafloor or washes onto coastlines.
Sources & Solutions
80% of ocean plastic comes from land-based sources via rivers. Ten rivers (eight in Asia) carry 90% of river-borne plastic to oceans. Solutions require both cleanup and prevention: better waste management in developing nations, reducing single-use plastics, and technologies like The Ocean Cleanup capturing debris.
