According to the Earth Times a Garbage Island is
the points of convergence are where the deposition of trash occurs and eventually build up to form floating trash islands. Floating Waste Dumps. An area of concentration for waste over the ocean has been the 'Great Pacific Garbage Patch' located between California and Hawaii.
About 80% of the debris in the Great Pacific Garbage Patch comes from land-based activities in North America and Asia. Trash from the coast of North America takes about six years to reach the Great Pacific Garbage Patch.
Injury to wildlife is one way the uptick in pollution has harmed delicate coastal ecosystems. When marine animals like sea turtles ingest plastic, it can damage their digestive systems and cause them to starve.
Though the Great Pacific Garbage Patch is the most widely publicized of the so-called trash islands, the Atlantic Ocean has one as well in its Sargasso Sea.
Obviously something must be done to stop this unfolding environmental disaster, even small grassroots steps can prevent the world's ecosystems from being irreparably damaged by plastic for generations to come.
