- 2. poster introduction Historyof plastic Composition of plastic The word plastic is derives from the Greek word plastikos meaning “Capable of being shaped or molded” we can give any shape to the plastic according to our requirement. Now today in this modern civilization plastics became a essential substance in our daily life like our food. The main reason of huge uses oaf plastics –it is Versatile, lightweight, waterproof, durable, and most of all, inexpensive. These attractive qualities of plastic have led us to use the material in virtually every form and way we can. the micro-beads in the facial foam we use to wash our faces every morning, to the water bottle and disposable utensils we eat and drink out of, plastic has become an ubiquitous and almost indispensable part of our lives. It was difficult to thought spend a day without using plastic. RAJKUMAR CHALL
- 4. poster introduction Historyof plastic Composition of plastic The plastic is an organic substance and it consists of natural or synthetic binders or resins with or without moulding compounds. In general, it may be stated that the plastics are compounds of carbon with other elements such as hydrogen, nitrogen and oxygen. Plastic are mainly produced in polymerization procedure .In this process uses chemicals are : Polyethylene, Polypropylene, Polystyrene ,Polyester , Polyamies, Polycarbonate etc. RAJKUMAR CHALL

Humans, however, have invented plastic which will always be ‘unnatural’ in the environment because of its properties. Making plastic is inexpensive and the applications of the material are endless. Because plastic is so widely used, it almost always ends up in the environment, causing more plastic pollution. And not just because someone leaves a piece of plastic on the street instead of putting it in a waste bin. RAJKUMAR CHALL

Of all the plastic we use, 40% is used just once. Every year we use several billion items such as bags, bottles, trays, and food packaging. Supermarkets are full of it. Some people are careless with packaging and leave it behind as litter. But there are also places where people can’t do otherwise because there is no waste collection system. It is without a doubt that even if most people do their best, much of that single-use plastic enters the environment, being one of the biggest cause of plastic pollution. RAJKUMAR CHALL

Some of the major long-term effects of plastic pollution are: 1. It Upsets the Food Chain Chain Because it comes in sizes large and small, polluting plastic even affect the world’s tiniest organisms such as plankton. When these organisms become poisoned due to plastic ingestion, this causes problem for the larger animals that depend on them for food. This can cause a whole slew of problems, each step further along the food chain. Plus, it means that plastic is present in the fish that many people eat every day. RAJKUMAR CHALL

Groundwater Pollution by plastic Water conservation is already a concern in places ranging from California to parts of India, but the world’s water is in great danger because of leaking plastics and waste. If you’ve ever seen a garbage dump, imagine what happens every time it rains – then imagine that being in your drinking water.Groundwater and reservoirs are susceptible to leaking environmental toxins. Most of the litter and pollution affecting the world’s oceans also derives from plastics. This has had terrible consequences on many marine species, which can lead to consequences for those that eat fish and marine life for nutrients – including people. RAJKUMAR CHALL

When these chemicals seep underground, they degrade the water quality. The wind carries and deposits plastic from one place to another, increasing the land litter. It can also get stuck on poles, traffic lights, trees, fences, towers, etc. and animals that may come in the vicinity and might suffocate them to death. RAJKUMAR CHALL

Air pollution by plastics When plastic burned in air it releases a host of poisonous chemicals into the air, including dioxin, the most toxic substance known to science. Dioxins are found throughout the world in the environment and they accumulate in the food chain, mainly in the fatty tissue of animals. Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer. RAJKUMAR CHALL

Effects on Marine Life Marine plastic pollution has effected over 267 species worldwide as a result of ingestion, starvation, suffocation, infection, drowning, and entanglement. The evidence of the plastic’s impact on marine life is ever mounting: It is expected that there will soon be more plastic in our oceans than fish. .Fifty to 80 percent of all sea turtles found dead have ingested some form of plastic. .Seabirds are beginning to unintentionally feed their chicks plastic, mistaking it for food, and one study found that 98% of the chick sampled had ingested some form of plastic.

Shop Friendly Plastic bags were once a modern convenience but can be efficiently replaced by reusable bags, many of which fold up compactly in order to be portable. Just think about how many bags you typically carry out of a grocery store, and multiply that by the number of times you grocery shop. That’s a lot of plastic! Carry a bag and always reuse plastic bags as much as possible if you have them. Use jute bag except of plastic carry bag. RAJKUMAR CHALL

What is worse, the recycled plastic degrades in quality and necessitates the production of more new plastic to make the original product. Recycling of plastic is very uneconomical, dirty and labour-intensive as has been revealed by a study conducted by the Public Interest Research Group, based in Delhi, India. RAJKUMAR CHALL

So, it is quite tough to stop plastic pollution. It`s use is so vast that applying the government`sregulations is not enough to stop using of plastic. But it is the only self awareness which can make us stop from using plastic.
