In 1988, the National Oceanic and Atmospheric
that a particular current in the North Pacific
Ocean might cause debris, to accumulate.
Nine years later, oceanographers were alerted
to the location of the “garbage patch”.
Similar patches now exist in every ocean formed
by oceanic currents, that cause marine
pollution to concentrate in one spot.
Experts estimate that 80% of the garbage come from land-based sources and consists of many types of debris such as: fishing nets, plastic micro-pellets, and chemical sludge. Strangely, an observer might not see large pieces of actual garbage floating in these patches. This is because plastic degraded into smaller and smaller pieces. Never fully biodegrading as organic material would. It can become small enough that marine animals ingest the pieces of plastic; causing it to enter the food chain of not only larger animals but in many cases humans.
The garbage patches maybe quite large, although it is difficult to measure their size because, much of the debris is suspended below the surface. However, estimates say that it could be anywhere from 270,000 square miles to 5,800,000 square miles. A number of organizations have began looking for ways to study address and potentially clean up the North Pacific garbage patch.
