Great Pacific Garbage Patch
The "Yellowwood Island" actually has two areas, described as an eastern patch and a western patch, which are separated because of ocean currents. Scientists estimate that the size of the "plastic island" is approximately equal to the land area of Texas, United States, but it could be as much as twice the size. Also, it is not really a floating island. It is more like a soup of plastic pieces floating in the ocean just below the surface.  It is  from California, between Hawaii and Japan.
