Plastic is one of the most important things in the modern life of human being. It can be molded into any desired shape. It is cheap as compared to other materials and has more strength. It is a part of our day-to-day life.
But, Plastic also carries a lot of disadvantages. It is harmful to the environment. It cannot be quickly degraded and damages the atmosphere if burnt. It can prevent seeping of water into the soil, reaching sunlight into water.
The toxic chemical released during the production of plastic is another demerit. Plastic has given numerous benefits to human life but It is also a cause of global warming and pollution in our surrounding. Let’s take a look at the negative effects of plastic in detail:
Plastic pollutes soil: Plastic buried in soil can release a toxic chemical which mixes into the ground making it harmful for agriculture and human use, it can also seep into the ground and mix with groundwater. This makes the water unhealthy for human consumption and agricultural use. Sometimes plastic such as polythene bags, get buried under the soil, this makes the soil toxic.
Plastic pollutes ocean: Plastic objects are left over into the ocean for biodegrading it. Plastics degrades faster in the sea, but it also leaves the harmful chemical into it, making it even more dangerous to the life on the earth. It increases the chance of Global Warming. The garbage thrown into the sea such as plastic utensils, polythene, etc. keeps floating into the sea. This prevents the sunlight from reaching the ground level of the sea. As a result, the life in the ocean doesn’t get enough sunlight. This prevents them from developing and stops their growth.
Plastic releases toxic when burned: In many rural and even urban areas, people set old plastic objects on fire in hope to get rid of it. Plastic contains a lot of chemicals which gets released into the atmosphere and mixes with the natural air. This makes the air we breath toxic and harmful. As a result, the air we breath is not pure and contains many types of hazardous chemical. When we breath contaminated air, it hurts our lungs and overall health in the long run.

Some ways to stop pollution due to plastic are:-
- Use jute bag instead of polythene
Polythene bags contribute a significant percentage to the usage of plastic. We use polythene bags most of the time. From buying vegetables from market to carrying goods. Polythene bags are very hazardous to the environment. They are non-biodegradable, and it is hard to get rid of this material. It can also cause harm to water life, human beings, and the environment. So, try to use jute bags when you go shopping.
- Reuse reusable plastic bottle
Nowadays, reusable plastic is used, which means you can refill these bottles with water and use them again. However, make sure that bottle is reusable otherwise toxic from the bottle may mix with the water.
Mostly CDs are made of poly-carbonate plastic. Every year, millions of CDs are sold. We can use pen drives or portable hard disks for carrying data as they can carry a large amount of data compared to CDs and are reusable too.
Apart from this, governments need to take some serious actions as well to stop the plastic usage where alternatives are available. It’s high time that the world understands the negative impact of plastic on nature. Do share your thoughts in the comments below.

This article is about a type of packaging. For the short film, see Plastic Bag (film). For the song, see Plastic Bag (Drake and Future song).
A plastic bag, polybag, or pouch is a type of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals, and waste. It is a common form of packaging.
Most plastic bags are heat sealed together. Some are bonded with adhesives or are stitched.
Several design options and features are available. Some bags have gussets to allow a higher volume of contents, some have the ability to stand up on a shelf or a refrigerator, and some have easy-opening or reclosable options. Handles are cut into or added into some.
Bags can be made with a variety of plastics films. Polyethylene (LDPE, LLDPE, etc.) is the most common. Other forms, including laminates and co-extrusions can be used when the physical properties are needed.
Plastic bags usually use less material than comparable to boxes, cartons, or jars, thus are often considered as "reduced or minimized packaging".
Depending on the construction, plastic bags can be suited for plastic recycling. They can be incinerated in appropriate facilities for waste-to-energy conversion. They are stable and benign in sanitary landfills. If disposed of improperly, however, plastic bags can create unsightly litter and harm some types of wildlife.
Bags are also made with carrying handles, hanging holes, tape attachments, or security features. Some bags have provisions for easy and controlled opening. Reclosable features, including press-to-seal zipper strips, are common for kitchen bags bought empty and for some foods. Some bags are sealed for tamper-evident capability, including some where the press-to-reseal feature becomes accessible only when a perforated outer seal is torn away.
Boil-in-bags are often used for sealed frozen foods, sometimes complete entrees. The bags are usually tough heat-sealed nylon or polyester to withstand the temperatures of boiling water. Some bags are porous or perforated to allow the hot water to contact the food: rice, noodles, etc.
Bag-in-box packaging is often used for liquids such as box wine and institutional sizes of other liquids.
Plastic bags are used for many medical purposes. The non-porous quality of plastic film means that they are useful for isolating infectious body fluids; other porous bags made of nonwoven plastics can be sterilized by gas and maintain this sterility. Bags can be made under regulated sterile manufacturing conditions, so they can be used when infection is a health risk. They are lightweight and flexible, so they can be carried by or laid next to patients without making the patient as uncomfortable as a heavy glass bottle would be. They are less expensive than re-usable options, such as glass bottles. Plastic bags and plastic wrap are also used to prevent water loss and hypothermia in very premature babies.

Plastic shopping bags
Main article: Plastic shopping bag
Open bags with carrying handles are used in large numbers. Stores often provide them as a convenience to shoppers. Some stores charge a nominal fee for a bag. Heavy-duty reusable shopping bags are often considered environmentally better than single-use paper or plastic shopping bags. Because of environmental and litter problems, some locations are working toward a phase-out of lightweight plastic bags.
American and European patent applications relating to the production of plastic shopping bags can be found dating back to the early 1950s, but these refer to composite constructions with handles fixed to the bag in a secondary manufacturing process. The modern lightweight shopping bag is the invention of Swedish engineer Sten Gustaf Thulin. In the early 1960s, Thulin developed a method of forming a simple one-piece bag by folding, welding and die-cutting a flat tube of plastic for the packaging company Celloplast of Norrköping, Sweden. Thulin's design produced a simple, strong bag with a high load-carrying capacity, and was patented worldwide by Celloplast in 1965.
From the mid-1980s onwards, plastic bags became common for carrying daily groceries from the store to vehicles and homes throughout the developed world. As plastic bags increasingly replaced paper bags, and as other plastic materials and products replaced glass, metal, stone, timber and other materials, a packaging materials war erupted, with plastic shopping bags at the center of highly publicized disputes.
In 1992, Sonoco Products Company of Hartsville, SC patented the "self-opening polyethylene bag stack". The main innovation of this redesign is that the removal of a bag from the rack opens the next bag in the stack. This team was headed by Wade D Fletcher and Harry Wilfong.
The number of plastic bags used and discarded worldwide has been estimated to be on the order of 1 trillion annually. The use of plastic bags differs dramatically across countries. While the average consumer in China uses only 2 or 3 plastic bags a year, the numbers are much higher in most other countries: Denmark: 4, Ireland: 20, Germany: 65, USA: > 300, Poland, Hungary, Slovakia: more than 400.
A large number of cities and counties have banned the use of plastic bags by grocery stores or introduced a minimum charge. In September 2014, California became the first state to pass a law banning their use. Local manufacturers of plastic bags, under the legislation, would receive financial support to assist them make more durable multi-use bags, that would be sold by grocery stores rather than given away, as were the plastic bags. In India, government has banned use of plastic bags below 50 microns.
Main article: Biodegradable bag
Main article: Phase-out of lightweight plastic bags
Non-compostable plastic bags can take up to 1000 years to decompose. Plastic bags are not capable of biodegradation but rather they photodegrade, a process by which the plastic bags are broken down into smaller toxic parts. In the 2000s, many stores and companies began to use different types of biodegradable bags to comply with perceived environmental benefits.
Plastic shopping bags escape the garbage collection process, and are also disposed of improperly and can end up in streams, which then lead them to end up in the open ocean. To mitigate marine plastic pollution from single-use shopping bags, many jurisdictions around the world have implemented bans or fees on the use of plastic bags. They can also have an impact on in urban environments. Waterways and drains can be clogged by plastic bags and have been linked to severe flooding. An estimated 300 million plastic bags end up in the ocean due to escaping the garbage. The way in which the bags float in open water can resemble a jellyfish, posing significant dangers to marine mammals and Leatherback sea turtles, when they are eaten by mistake and enter the animals' digestive tracts. After ingestion, the plastic material can lead to premature death. Once death occurs and the animal body decomposes, the plastic reenters the environment, posing more potential problems. 
Marine animals are not the only animals affected by improper plastic bag disposal. Penguins can get trapped and suffocate because of the bags. Plastic bags can also be mistaken for materials used in a bird's nest, which could lead to accidental ingestion of the plastic. Additionally, sea birds, when hunting, sense for dimethyl sulfide (DMS) which is produced by algae. Plastic bags are a breeding ground for algae, so the sea birds mistakenly eat the bag rather than the fish that typically ingests algae. (National Geographic)
Even though the bags are plastic, most recycling plants do not recycle them. The type of plastic[clarification needed] in plastic bags makes it difficult to be recycled into new material. Additionally, the material frequently causes the equipment used at recycling plants to jam, thus having to pause the recycle machinery and slow down daily operations.

Danger to children
Thin conformable plastic bags, especially dry cleaning bags, have the potential for causing suffocation. About 25 children in the United States suffocate each year due to plastic bags, almost nine out of ten of whom are under the age of one. This has led to voluntary warning labels on some bags which pose a hazard to small children.
Plastic bags are used for diverse applications:
Multiple chambers for eventual mixing
Porous bag for cooking rice
Travel toiletries in a reclosable plastic bag
Woven plastic fiber bags used for sand

In June 2009 Germany’s Institute for Energy and Environmental Research concluded that oil-based plastics, especially if recycled, have a better life-cycle analysis than compostable plastics. They added that "The current bags made from bioplastics have less favourable environmental impact profiles than the other materials examined" and that this is due to the process of raw-material production.
