What is the Great Pacific Garbage Patch?
The Earth has about five main oceanic gyres. Ocean gyres are huge spirals of seawater formed by colliding currents and it just so happens that one of
the largest gyres is the North Pacific Subtropical Gyre, which covers almost all of the space between California and Japan. Located a couple hundred
miles north of Hawaii, warm water from the South Pacific meets with the cool water from the North Pacific. This area constitutes the North Pacific
Subtropical Convergence Zone and this is where the garbage gathers.
The Patch’s size has been hard to measure. The common belief is that it is twice the size of Texas, but others say that is a gross exaggeration and
others say it is even larger. It is hard to determine because the trash does not stay in one place to actually form an island. It moves around and sinks.
Also, 90% of the garbage in the patch is plastic which is not biodegradable. The plastic photo-degrades breaking the objects down to little tiny bits.
This process makes the plastic less of an actual object and more of a soup-like creation in the ocean waters, again making it impossible to measure.
This large amount of plastic even overrides the amount of zooplankton in the water by a six to one ratio!
