The Great Pacific Garbage Patch, sometimes called the Eastern Pacific Garbage Patch and Pacific Garbage Gyre, is a floating patch of garbage that has collected in the Subtropical Gyre of the North Pacific, which lies in the middle of two high pressure areas between Hawaii and California. Most of the waste, also called marine debris, in the area is plastic, but there are also objects made from other materials such as glass and rubber. Although the trash patch is too large and goes too deep below the ocean's surface for scientists to determine exactly how much trash is in it, they have collected up to 750,000 pieces of plastic in one square kilometer (CITE). This type of debris floating in the ocean is dangerous for several reasons. An important reason is that marine animals mistake some trash, especially plastic, for food (CITE). Another reason floating debris is so dangerous is because it can block sunlight from reaching the deeper levels of the ocean and, therefore, remove the energy source for many autotrophs such as algae....
