The modern day society is technologically oriented, with virtually every activity being conducted with the help of various forms of technology. The implication is that the world has seen a massive rate of large-scale production of technology devices. Estimates point out that close to 50 million tons of e-waste are produced globally (Lepawsky & Mcnabb, 2010). The developed countries are the primary producers of this waste, with the role of doing away with the waste left to the poorer developing countries. In the US and Canada for example, close to 80% of all electronic waste is exported to Asia and Africa (Lepawsky & Mcnabb, 2010). These poor communities lack advanced means of processing this waste, and this yields various social, economic and environmental impacts to these countries.
Social aspects
Historical data indicates the adverse social consequences that electronic waste has, especially in the developing countries that are used as dumping sites of e-waste by the wealthy nations. The social effects primarily touch on the compromising of the well being of the residents of these poor countries. In Nigeria, for example, the lives of villagers who wholly depended on agriculture were negatively impacted by polychlorinated biphenyls, which were produced by Italian waste dumped into their farms (Lepawsky & Mcnabb, 2010). This case had many villagers report of strange sicknesses that could be traced back to the e-waste. The social impact of e-waste is therefore mainly felt through the health outcomes of the communities used to process the waste.
The social implications of e-waste are also conceptualized when the health outcomes for the residents of Gaiyu, China is considered. According to researchers, this is one of the world’s biggest centers used for the processing of this kind of waste. The city has been involved in the handling of the waste for more than four decades, with more than 80% of the families in the area actively engaged in the recycling process of e-waste (Lin et al., 2013). Given that these workers engage in this activity without taking the necessary health precautions, research reveals that Guiyu residents had high levels of toxic heavy metals and other organic poisons in their blood, hair, milk and umbilical cords. Lin et.al (2013) review the literature on the health outcomes of people in this area, with results indicating that these residents had higher rates of stillbirths, Low Birth Weight, and Intrauterine Growth Retardation cases compared to the other Chinese towns not involved in e-waste recycling.
The literature review also revealed that the toxins from the e-waste processing activities were linked to temperament alterations especially in children. Besides, the children in these areas run the risk of developing nervous system complications. In a study that looked into the effect of cadmium pollution to pregnancies revealed that this toxin has the potential of causing shortened placental telomere length. Also, Cadmium was noted to have adverse implications for the development of the yolk sac and embryo, while predisposing children to cancer (Lin et al., 2013).
Environmental aspects
The environmental aspects of e-waste are some of the widely documented scholarly topics. Environmentalists, governments, and non-governmental organizations have documented the adverse effects of electronic waste. This has led to the development of various accords that seek to manage the handling and management of e-waste. Some instances have gotten worldwide attention in regards to e-waste. The 1986 incident where a Norwegian ship tried to dump waste on a beach in Haiti shows the fear around electronic waste (Lepawsky & Mcnabb, 2010). The adverse environmental impacts associated with e-waste are a major concern due to the problematic nature of handling the large quantities of e-waste. Due to the modern day technological advancements, a variety of technology devices are used, meaning that there is a multiplicity in regards to the types of waste accumulated (Sullivan, 2014).
In a review of the literature on e-waste management, Sullivan (2014) finds out that there is an increase in the rate of release of carcinogenic dioxins and polyaromatic hydrocarbons due to the random burning of plastic. The environmental impact of toxins arising from improper e-waste management systems is becoming clearer, especially in the degradation of the environment is areas used for e-waste processing. The review also shows that the toxins from this waste are expected to influence not only the current generation but also generations in the future. Given that most electronic devices are often made up of toxic material such as arsenic, lead, and mercury, these toxins often find their way into the soil and water. During the recycling process, these toxins leach into the soil, especially during the rainy seasons. Overall, the toxins end up in water, soil and air, thus intoxicating the whole food chain.
In a study that looked into the environmental effect of e-waste to Ikeja, Nigeria, the results indicated that water in the region had high concentrations of heavy metals. The soil in this e-waste processing area also showed a high concentration of toxins, especially lead when compared to other parts not involved in e-waste processing (Sullivan, 2014).These results build on the literature suggesting that electronic waste processing in Nigeria, which was usually illegal contributed to high levels of environmental pollution. The toxic pollutants have grave impacts on the natural ecosystems; which poses a threat to global biodiversity.
Economic aspects
There is an economic perspective to electronic waste. An essential aspect to consider here is the fact that the processing of e-waste requires a significant investment in regards to human resources. An argument is therefore made that dumping of e-waste into developing countries offers an opportunity for the unemployed public to make a living. Despite this being true, the situation can be translated as one where rich countries take advantage of the economic insecurities of poor people in developing countries for their benefit (Lepawsky & Mcnabb, 2010).
Another aspect to consider in the economic perspective to e-waste is the supposed positive impact that re-used electronics have to the economies of developing nations. In these nations, the demand for electronic appliances is as high as the rates in the developed nations. The second-generation items from developed countries have, therefore, helped in the dawning of the digital age in these countries. The dumping of electronic waste has therefore seen the availability of affordable digital electronic devices (Sullivan, 2014). A problem arises once these cheap devices become non-repairable. The devices become waste, which has a variety of adverse environmental and social impacts.
The overall argument is that despite the fact that dumping of e-waste provides an economic reprieve to the poor people in developing countries, the long-term effects are diverse. E-waste and used electronics pose environmental and health hazards. In the end, the countries that process this waste will incur costs tied to medical care and loss of labor. This is because more people will continue being adversely affected by toxins from the waste, with the development of children compromised and cases of early death being common (Sullivan, 2014).
In conclusion, the demand for electronic appliances has led to an increase of electronic waste dumped into developing countries. This waste has various effects, with the economic, social and environmental aspects covered in this research. What stands out, however, is the disregard to the concept of sustainable development, where the activities of the current generation poised to compromise the ability of future generations to meet their needs.
