With the advancement in technology and easy availability at low price across the globe, there has been a tremendous increase in the use of cell phones. The use of smart phones has resulted in mobile addiction across the globe. It is very much necessary to stay connected through smart phones with numerous features like social networking, banking facilities, high speed internet and entertainment options. It almost performs the function of the PCs with the use of MS Office possible in the smart phones. Hence, the large scale increase in the use of smart phones, there are a few disadvantages which are in the form of hazards to the mankind and environment on the whole. These hazards have to be handled effectively and should be taken as a priority to save the environment and human from the harmful effects of the toxic substances.
Importance of the topic and rationale of study:
The use of the cell phones is increasing tremendously across the globe. It is found that the number of cell phones has way crossed the figure of 6.8 billion which is almost going to equal the human population of the world (Wang, Chen, & Liu, 2012). This serves to be good from the technical point of view, but at the same time, the large quantity of hazardous wastes that are created by them tend to be a major threat in the future for mankind. We observed that green computing helps the proper disposal and recycling of the hazardous materials that is produced by the unsafe parts of the mobile phones when they are of no use or are dumped in the regular trash. It has to be considered as one of the most optimum solution for the problem of handling the wastes that is created by cell phones. The topic is noteworthy due to the following reasons:
• The number of mobile phone users reached 6.8 billion in 2013 from 2 billion in 2005. This has to be considered significantly to solve the problem of pollution that is being created by the hazardous material present in the mobile phones (Wang, Chen, & Liu, 2012) .
• The cell phones are not turned off when not in use during the nights when the user is sleeping and hence there is a great amount of power and energy wasted in the form of the radiation that is generated by the battery during this time (Geyer & Blass, 2010).
• The number of mobile phones is easily going to cross the figure of 7 billion by 2015 which would be the population of the world at that time. Thus, the use of such large number of cell phones by individuals would result in to tremendous increase in ensuring safety from the radiation that is generated in them (Wang, Chen, & Liu, 2012).
• Every day there are more than a million cell phones produced. The fact that the cell phones that have become old can be either repaired or recycled if it is of no use can be a good solution to the management of the hazardous wastes that would be created by disposing them improperly (Geyer & Blass, 2010).
• It is observed that an average time in which an individual changes his mobile device is 20 – 24 months which means that every 2 years, a large number of mobile phones are either of no use or need to be repaired. This figure is very alarming and calls for an action for encouraging the proper recycling or repairing of such cell phone devices (Geyer & Blass, 2010).
The study of the concept of green computing helped us to learn various aspects that are to be understood and considered while developing a critical analysis of the subject. It helped us to generate few learning outcomes which are discussed below:
There are a wide range of technological solutions that are available for executing the green computing of cell phones in the countries. It involves using more environment and human friendly materials for producing the chips that are used in the cell phones which largely consist of lead and arsenic. There has to be proper care which is to be taken while developing the technology in cell phones to make sure that it does not get excessively heated which would multiply the amount of radiation that it emits. The technological aspect of reusing the chips and circuits of the old cell phones in developing the new devices serves as a great step in the green computing of the cell phones (Geyer & Blass, 2010).
Green computing of the cell phone devices have to be considered as a collective responsibility of each and every individual. People are directly or indirectly affected by the hazardous material in cell phones on long term basis and there has to be a sense of understanding that has to be inculcated among the people across the globe to overcome this problem. It can be started on an individual level by ensuring that one shuts down the devices when they are not in use and at the same time make them work on power saver modes to minimize the amount of radiation that is emitted through them. It serves to be a common goal of the mankind that is to be shared equally by contribution from each and every person in the process of green computing of the mobile phones. UAE has taken significant measures in ensuring that the hazardous material in the cell phones is disposed of safely through developing recycling centres at various places and also encouraging people to use them by providing them with benefits in the form of schemes and concessions (Ahmed, 2013).
The issue of handling the hazardous wastes created through cell phones tends to be the problem of all the nations across the globe. There is generation of a large amount of radiation daily through the use of the cell phones. At the same time, there is a wastage of great quantity of power and energy by the people. Hence, considering the social responsibility of saving the environment from the hazardous effects of the cell phones that can be tackled through green computing have to be undertaken as a priority in each and every culture (Geyer & Blass, 2010)..
The generation of heat in the cell phones is due to the consumption of battery and internet services over the phone. The excessive heat that is generated can be controlled by turning off the internet when not in use and to control the usage and multiple downloads across the devices. The disposal of cell phones in the soil will damage the soil and when the disposed parts gets mixed with the water resources. There are various other steps and information about reducing the hazards of the cell phone use which is provided here further. Using the power saver option in the devices, turning off the system when not in use and cautiously handling the toxic wastes that is created by the devices after they are no longer in use. These are the various means through which green computing can be adopted and applied to save the world from the harmful effects of the toxic materials present in the cell phones. (Harmon, Demirkan, Auseklis, & Reinoso, 2010).
Reflective learning outcomes
Understanding the subject in the form of problem based learning has helped us to develop a better bonding among the team members while developing various solutions for the problem. It helped us to involve the understanding and logic of all the members in the team. The group interaction during the project helped us to develop a critical thinking of the green computing through brainstorming among all the team members. Team work helped us to gather a large amount of data regarding the project about the hazards of cell phones by each and every member of the team.
The only problem that was faced during the team work was dominance of few members in developing the solution that supressed the opinion of other team members and did not allow them to express their views openly. Thus, it could be observed that using team work technique would be more effective if a balanced and equal input is taken from each and every member without the dominance of any specific member in the decision making process.
Problem based learning helped to develop a clear understanding and evaluation of the topic. This approach helped us to develop maximum possible solutions that would be feasible for the problems that are specified and observed in the project. The use of Problem based learning technique should not be made for the projects that require a complete understanding of the process or terms that would involve a detailed description of the concept. Hence, it can be recommended that the Problem based learning could be recommended for the projects that involve critical analysis of the terms and issues that are existing in the market.
