essay on plastic pollution
Answers
Explanation:
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.
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.
Explanation:
Plastic pollution is the accumulation of plastic objects and particles (e.g.: plastic bottles and much more) in the Earth's environment that adversely affects wildlife, wildlife habitat, and humans. Plastics that act as pollutants are categorized into micro-, meso-, or macro debris, based on size.Plastics are inexpensive and durable, and as a result levels of plastic production by humans are high.However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade. Together, these two factors have led to a high prominence of plastic pollution in the environment.
Plastic pollution can afflict land, waterways and oceans. It is estimated that 1.1 to 8.8 million metric tons (MT) of plastic waste enters the ocean from costal communities each year.[6] Living organisms, particularly marine animals, can be harmed either by mechanical effects, such as entanglement in plastic objects, problems related to ingestion of plastic waste, or through exposure to chemicals within plastics that interfere with their physiology. Effects on humans include disruption of various hormonal mechanisms.
As of 2018, about 380 million tons of plastic is produced worldwide each year. From the 1950s up to 2018, an estimated 6.3 billion tons of plastic has been produced worldwide, of which an estimated 9% has been recycled and another 12% has been incinerated. This large amount of plastic waste enters the environment, with studies suggesting that the bodies of 90% of seabirds contain plastic debris.[8][9] In some areas there have been significant efforts to reduce the prominence of free range plastic pollution, through reducing plastic consumption, litter cleanup, and promoting plastic recycling.
Some researchers suggest that by 2050 there could be more plastic than fish in the oceans by weight...
