The "Great Pacific Garbage Patch" is a massive area in the North Pacific Ocean where marine debris, mostly consisting of plastic waste, accumulates due to ocean currents. It is not a solid patch of garbage as the name suggests, but rather a region with high concentrations of floating trash. The formation of the Great Pacific Garbage Patch is primarily due to the ocean currents, known as gyres, that trap and concentrate debris in this area. Additionally, improper disposal of plastic waste from land-based sources and maritime activities contribute to the growth of this environmental issue.
