Monofilament is not biodegradable and can last hundreds of years depending on environmental conditions. Because it is thin and often clear, it is very difficult for birds and animals to see. They can easily become entangled resulting in injury, drowning, strangulation or starvation. Many animals also mistakenly ingest fishing line.
It is also difficult for people to see as well. People often drive their boats over floating line and damage their engines. Divers and swimmers can also be affected since they unable to see line when they are in the water.
