Plastic is the general common term for a wide range of synthetic or semi synthetic organic amorphous solid materials suitable for the manufacture of industrial products. Plastics are typically polymers of high molecular weight, and may contain other substances to improve performance and/or reduce costs.
Man-made plastics are called Synthetic Plastics. Synthetic plastics are usually made from crude oil, but, coal and natural gas are also used. These plastics do not decompose easily and, hence, lead to death by choking of cattle and other herbivores, when carelessly thrown in green pastures.
Burning of plastic bags and items leads to the creation of noxious fumes, such as carbon monoxide. The increase in the effusion of this gas has led to an upsurge in the people suffering from various respiratory ailments such as asthma and bronchitis. The noxious fumes have also had an injurious effect on the ozone layer, which prevents the harmful rays of the sun from inflowing the atmosphere. The thinning of this layer has increased incidences of skin cancer . The soil fertility deteriorates as the plastic bags form parts of manure remain in the soil for years.
Plastic bottles, plastic bags and food packaging are responsible for most of our plastic waste. The most common symbols of our disposable culture are beverage bottles, plastic bags, coffee-stirrers, and styro foam - the most ephemeral of ephemera. But, paradoxically, the chemicals in these items will be with us forever. Plastic is one of the few new chemical materials which poses an environmental problem. Polyethylene, polyvinyl chloride, polystyrene is largely used in the manufacture of plastics.
A recent US report concluded that more than 100,000 marine mammals die each year in the world’s oceans by eating or becoming entangled in plastic rubbish, and the position is worsening world-wide. Plastic bags are the cause of major environmental concerns.
Statistics show that we are consuming more and more plastics every year. It is estimated that an average individual uses around 130 plastic bags per year. Plastic bags are everywhere and every day, we are handed countless plastic bags when we go to the grocery store, retail clothing store, book store, restaurants, etc. In the US each year over 25 billion single use plastic water bottles are bought, used once, only part of the contents consumed most of the time, and discarded and merely 20 percent of those bottles will be recycled while the rest will lay in landfills for the next few thousand years and end up in the oceans which ends up polluting our food chain and is hurting human health.
The world's oceans contain millions of tons of plastics, most of which are discarded on land and wend their way down rivers and along coasts until eventually they are carried into the middle of the sea. Plastic is the largest source of ocean litter. Plastic bags take up to 500 years to decompose in the water and in the meantime contribute to the deaths of 10,000s birds and marine mammals each year.
The UN’s top environmental official already called for a global ban on plastic bags many times. "Single use plastic bags which choke marine life should be banned or phased out rapidly everywhere. There is simply zero justification for manufacturing them anymore, anywhere," said Achim Steiner, executive director of the U.N. Environment Program
Plastic Products after use isn't the producers' problem. It becomes the planet's problem. Plastic wastes choke seas across the globe. This form of pollution is one of the biggest environmental problems we face, and it's only getting worse as plastic production continues to grow.
Plastic fragments of all sizes have appalling effects on marine organisms, but perhaps a greater threat to humans is encountered on a microscopic level.
One of the most common chemicals in plastics is Bisphenol A more-widely known as BPA. This compound is an endocrine disruptor which can mimic oestrogen and has been linked with an array of afflictions as diverse as diabetes, heart disease, breast cancer, thyroid disorders, ADHD, infertility, erectile dysfunction, early-onset menstruation and obesity. Bisphenol A or as BPA and other persistent organic pollutants (POPs) can pass through the placental wall and might also enter infants through breast milk.
More than a 100 million tonnes of plastic is produced world-wide each year. In Asia plastic use in daily exercise is more common. Plastic packaging restrictions are being enacted or proposed across the continent, including in Pakistan, India, Malaysia and the Philippines. China was also among the first Asian countries to restrict plastic bags, in 2008.

Plastic |
Adverse Health Effects |
Common Uses |
|
Polyvinyl |
Can cause cancer, birth defects, genetic changes, chronic bronchitis, ulcers, skin diseases, deafness, vision failure, indigestion, and liver dysfunction |
Food packaging, plastic wrap, containers for toiletries, cosmetics, crib bumpers, floor tiles, pacifiers, shower curtains, toys, water pipes, garden hoses, auto upholstery, inflatable swimming pools |
|
Phthalates |
Endocrine disruption, linked to asthma, developmental and reproductive effects. Medical waste with PVC and phthalates is regularly incinerated causing public health effects from the release of dioxins and mercury, including cancer, birth defects, hormonal changes, declining sperm counts, infertility, endometriosis, and immune system impairment. |
Softened vinyl products manufactured with phthalates include vinyl clothing, emulsion paint, footwear, printing inks, non-mouthing toys and children’s products, product packaging and food wrap, vinyl flooring, blood bags and tubing, IV containers and components, surgical gloves, breathing tubes, general purpose lab ware, inhalation masks, many other medical devices |
|
Polycarbonate, with Bisphenol A |
Scientists have linked very low doses of bisphenol A exposure to cancers, impaired immune function, early onset of puberty, obesity, diabetes, and hyperactivity, among other problems (Environment California) |
Water bottles |
|
Polystyrene |
Can irritate eyes, nose and throat and can cause dizziness and unconsciousness. Migrates into food and stores in body fat. Elevated rates of lymphatic and hematopoietic cancers for workers. |
Many food containers for meats, fish, cheeses, yogurt, foam and clear clamshell containers, foam and rigid plates, clear bakery containers, packaging "peanuts", foam packaging, audio cassette housings, CD cases, disposable cutlery, building insulation, flotation devices, ice buckets, wall tile, paints, serving trays, throw-away hot drink cups, toys |
|
Poly ethelyne |
Suspected human carcinogen |
Water and soda bottles, carpet fibber, chewing gum, coffee stirrers, drinking glasses, food containers and wrappers, heat-sealed plastic packaging, kitchenware, plastic bags, squeeze bottles, toys |
|
Polyester |
Can cause eye and respiratory-tract irritation and acute skin rashes |
Bedding, clothing, disposable diapers, food packaging, tampons, upholstery |
|
Urea- |
Formaldehyde is a suspected carcinogen and has been shown to cause birth defects and genetic changes. Inhaling formaldehyde can cause cough, swelling of the throat, watery eyes, breathing problems, headaches, rashes, tiredness |
Particle board, plywood, building insulation, fabric finishes |
|
Polyurethane |
