Fishing nets, ropes, & lines lost at sea are the most hazardous type of debris in the ocean. Lost or abandoned from fishing vessels, ghost nets can be up to 6 kilometres long and are known to kill more than 200 species of marine animals and birds. Each year countless marine animals become victims of a cruel and silent killer. It is estimated that over 100,000 animals die each year from ghost nets.
One of the most tragic impacts from marine debris is wildlife entanglement. Fishing nets, ropes, line, balloon string, six-pack rings, and a variety of marine debris items can wrap around and strangle marine animals. Entanglement can lead to injury, illness, suffocation, starvation, and even death.
Many animals, such as sea turtles, seabirds, and marine mammals have been known to ingest marine debris. The debris item may be mistaken for food and ingested, an animal's natural food (e.g. fish eggs) may be attached to the debris, or the debris item may have been ingested accidentally with other food. Debris ingestion may lead to loss of nutrition, internal injury, intestinal blockage, starvation, and even death.

Marine debris can scour, break, smother, and otherwise damage important marine habitat, such as coral reefs. Many of these habitats serve as the basis of marine ecosystems and are critical to the survival of many other species.
Marine debris is an eyesore along shorelines around the world. It degrades the beauty of the coastal environment and, in many cases, may cause economic loss if an area is a popular tourist destination. Would you want to swim at a beach littered in trash? And, many coastal communities may not have the resources to continually clean up debris.

Our goal is to spread knowledge of the issue of marine debris. Planet Love Life directly supports beach cleanups and removal of marine debris. Beach rope removal is a step in the right direction and helps to prevent wildlife entanglements.
