The most prevalent type of micro-plastic found in the ocean is fishing nets that has been abandoned or discarded, also known as "ghost fishing nets." This problem worsens each year. These nets pose the greatest threat to marine life among all types of plastic. Even when lost at sea, they remain a hazard by ensnaring marine creatures. Made from durable plastics, these nets can continue trapping animals for more than 500 years unless they are taken out of the ocean.
