Answer:
In the last decade, plastic has affected the health and life of human beings very badly. Some incidents have attracted the attention of the whole world and put a question mark about the use of plastic in daily life.
Plastic, the wonder material that we use for everything and which pollutes our environment, is perhaps the most harmful of trash dumped by mariners and sea-goers in sea because it does not readily break down in nature. In-fact, the plastic that goes over the side today may still be around in hundreds of years to foul up the fishing gear, boat propellers, and beaches of future generations.
Careless disposal of plastic can have dire consequences. A plastic bag looks like a tasty jellyfish to an indiscriminate feeder like the sea turtle, but plastic is indigestible. It can choke, block the intestines of, or cause infection in those animals that consume it.
A plastic bag can also clog an outboard engine’s cooling system. Lost or discarded monofilament fishing line can foul propellers, destroying oil seals and lower units of engines, or it can become an entangling web for fish, seabirds, and marine mammals.

Follow me.
According to the Centre for Marine Conservation, over 25,000 pieces of fishing line were collected from U.S. beaches during the 1996 annual beach clean-up and at least 40% of all animal entanglements reported during the clean-ups involved fishing line.
Every day, more and more plastic is accumulating in our oceans. Recreational boaters are not the only group that improperly disposes off plastic refuse at sea. Plastics also enter the marine environment from sewage outfalls, merchant shipping, commercial fishing operations, and beachgoers.
In the middle stage, it is very flexible and can be given any shape depending on temperature and pressure. In practices, urea, formaldehyde, poly ethylene, polystyrene, polycithylcholide, phenoloic compounds and other substances are used in the preparation of plastics pollution.
Now-a-days the most popular plastic pollution is caused is polyvinyl chloride (P.V.C.). When any food material or blood is stored in the said plastic containers then gradually the soluble chemical gets dissolved in them causing death due to cancer and other skin diseases.
Polyvinyl chloride has also been found to destroy the fertility of the animals and their respiratory systems. When mixed with water, it causes paralysis and also damages bones and causes irritation to the skin.
Recently U.S.A. has banned the use of P.V.C. plastic in space apparatus and in food containers (as chemicals get dissolved in the food). India should immediately ban the use of P.V.C. in water pipes, food and medicine containers to save the lives of millions who are already suffering from different types of ailments.
