Ocean Gyres and Trash

A gyre is a current vortex that is located in the central areas of the oceans. the pacific ocean has two, one in the north and one in the south. the north pacific gyre has gotten the most attention for the amount of trash that has accumulated in it, but every ocean gyre has this problem. it is the nature of the beast. the trash is carried by the currents into the gyre where it circulates. since plastic mostly floats it is exposed to the sun and eventually photodegrades, which is when the plastic gets broken down slowly by the sun. this creates plastic nodules (little pellets of plastic) that fish mistake for food. the effects of plastic on marine life are not fully known at this time.
