Millions of plastic bags are given out to consumers by supermarkets and stores to carry their goods in. They are also cheap, light, durable, easy to carry and in many cases, free. The most commonly used shopping bag is made of High Density Polyethylene (HDPE). This type is used in the majority of supermarkets and stores. After these bags are used, they often end up in landfills or as litter, roughly only three percent of plastic bags is actually recycled per year (Planet Ark, 2011). The materials used in making plastic bags make them non-biodegradable. According to the science dictionary, 2011 refers to “these materials cannot be decomposed into environmentally safe waste materials by the action of soil bacteria.” These harmful substances are toxic and take approximately four hundred years to break down, or in this case photo-degrade; which is how plastics made from (HDPE) break down. Since they are not biodegradable, they remain in the environment and are absorbed in soil or water (Indian Centre for Plastics in the Environment, 2010). This essay will discuss the various harmful effects of plastic bags, and demonstrate the risks that these bags impose on humans, animals and the environment. It will also discuss a series of suggested solutions that could help reduce plastic bag usage.
Although plastic bags appear to be fragile and light, their negative environmental effect is devastating. Plastic bags may cause large amounts of pollution in every step of their limited life cycle, from the extraction of raw materials, production, transportation, and recycling or disposal. Plastic bags can be defined as the most damaging form of environmental pollution. They can have a damaging effect on marine animals and wildlife in addition to the aesthetic effects on beaches, parks, and trees. Plastic bags are potentially one of the main causes of death to marine animals (Harbor keepers,2008). Up to one hundred thousand marine animals or more die each year from eating plastic bags which are mistaken for food. This can result in blocking the animal’s intestines and possibly lead to the animal’s death. Another possible situation is that wildlife, such as birds, can get tangled in plastic bags causing choking and immobility, which may eventually lead to death. (Senior, 2008) and (Citizen Campaign, 2010). In other situations, after plastic bags photo degrade they remain toxic and could be eaten by fish, shellfish or any other marine life and survive this allows the toxins to enter our food chain through bioaccumulation (Puget Soundkeeper Alliance, 2011).

Plastic bags are the preferred mode of packaging for many products in the markets of today. This is due to the fact that they are light, inexpensive and easy to produce. They are also utilized in agriculture for cultivating crops in controlled environments besides being used in the manufacture of protective material. However, plastic is made of synthetic polymers that constitute the non-biodegradable and inorganic material like Styrene (Aquinus, 2010). The nature of the plastic material makes its disposal a challenge that leads into pollution. This research looks into the dangers brought about by the use of plastic bags and possible solutions to the problem.

Dangers of plastic bags

Plastic bags present various forms of dangers and hazards to human beings and the environment. To start with, pose a hygiene problem as their poor disposal leads to blockage of sanitary and drainage systems. This accelerates cases of water borne illnesses amongst people in the neighborhoods (Mathias, 2009). Moreover, the lack poor disposal of plastic bags affects agricultural activities as it hinders water penetration into the soil besides interfering with the formation of manure. To add to this, the photo-gradable plastics are easily broken down by light into chemicals that are harmful in nature (Bushnell, n.d). The production of the bags results into environmental pollution as chemicals emitted into the atmosphere interfere with the water and rainfall cycles. The manufacture of the bags is also viewed as wastage of natural resources as it depletes the quantities of petroleum that could have been potentially helpful in other areas (Vera, 2010).

Animals are also negatively affected as consumption of plastic. Poor disposal results in death and suffocation for aquatic animals. Marine life is affected by plastic bags disposed into the sea, for instance the case spotted at the North of the Arctic Circle as well as the South close to the Falkland Islands (Moorthy, 2010). Studies indicate that plastic bags constitute 10 percent of waste deposited at the U.S coastline. Furthermore, the increased deposit of plastic bags at one location leads to increased toxicity as they breakdown into petro-polymers.  In the long run, the toxic substances attributed to these plastic bags end up in the food chain as they are transformed into microscopic particles (World-Wildlife-Fund-Report, 2003).

Over the years, debate has been raging on whether to ban the use of plastic bags. People opposed to the ban argue that the perfect remedy would be to educate people on proper plastic bags disposal.  Plastic bag are compared to the other household accessories such as needles in that parents teach children on the usage and should therefore user education is imperative as well (Vera, 2010). This idea is however limited by the fact that educating people is a challenging task. In India for example, a family unit has been found to use an estimated 10 kilogram every year. Countries such as Bangladesh and China have prohibited the use of plastic bags to mitigate the effects they have on the environment. Other countries in Europe such as Ireland have imposed heavy taxation on the utilization of plastic bags while in Africa, Rwanda banned the use of the material (Erikson, 2010). The efforts to prohibit the use of these bags have been limited by the commercial gains attributed to the plastic bags that reduce support for laws against them. This is in addition to the observation that developing countries make up a major market for the bags from the developed world.

In conclusion, the plastic bags are a convenient method of packaging and transport for products but one that is hazardous to the environment, animals and marine wildlife as well as human beings. Its effects include death, pollution and waterborne diseases. This problem should therefore be solved through methods such as recycling and use of degradable plastic.
