4. Nowadays we have become a throwaway society with where its common to throw away devices and gadgets instead of repairing them. Why is this happening? What are the effects of this?
Nowadays, people are accustomed to discarding their damaged devices and tools instead of fixing them. There are a variety of reasons for this which can cause detrimental effects on the environment. In my opinion, three main factors are to blame for this environmental issue. Firstly, in some situations, the gadgets have a poor quality as their repairing would be impossible if they cannot work properly. Secondly, some countries do not have enough facilities such as essential accessories or experts for mending the broken tools. For instance, underdeveloped countries which import some of their machines from abroad might be unable to supply their required equipment to fix damaged products. Finally, in the case of spoiled devices, it is sometimes more convenient for people to purchase a replacement, because it just takes less than an hour in comparison with the longtime of repairing. Undoubtedly, discarded instruments could be the source of harmful effects on the nature. The major impact is that these remains are often not recycled on time, therefore remain in the environment which can increase pollution. Besides, when gadgets are not be fixed, high consumption of energy would be required for manufacturing a similar one, wasting both time and energy. Furthermore, raw materials are being depleted due to excessive use of them in production lines. Therefore, it is preferable to mend damaged devices, especially the tools that are fabricated by non-renewable resources.In conclusion, although in modern society individuals tend to jettison damaged machines and gadgets instead of repairing them, I think countries should introduce a scheme to prevent the negative effects of this misbehavior.
