Nowadays, reducing the frequency of flights or stopping flying has become more popular among travelers. From my perspective, while this reduction in the number of flights can bring about some benefits, I strongly believe that its drawbacks are far more significant. Admittedly, limiting the flying time can result in some positive impact on the environment. One important reason is that it can cut down on the amount of fuels used for airplanes. Specifically, airplanes require a massive amount of petrol for operation, which is then converted into exhaust fumes, one main culprit of air pollution. Therefore, reducing flights can ensure better air quality for urban regions, thus improving citizens' health. Moreover, this development can ensure against the overexploitation of these resources. As the demand for supplying fuels for planes decreases, there might be sufficient use for future generations and prevent potential scarcity. This can also reduce the risks of related serious environmental issues such as devastating floods and severe droughts. By contrast, I am convinced that the disadvantages of this limitation are far weightier. Initially, there might be a serious deficiency of transportation. Since airplanes often play strong roles in transportation, not only in travelling but also in deliveries, many people can be struggling with finding alternative vehicles comparable to planes in terms of convenience and capacity for their regular use. Furthermore, this reduction can put a great strain on the economy, especially on tourism. When the main means of transport for international tourism loses their dominance, many tourism companies may lose their profits as less foreign visitors travelling to tourist sites. This situation can be exacerbated when tourism accounts for the highest proportion in some countries' GDP such as Viet Nam or Thailand. In conclusion, it is true that some positive outcomes such as the enhanced air quality and the sufficiency of natural resources. However, I still believe that the frequency of flights should not be limited as some issues including the shortage of convenient transportation and negative effects on tourism can arise.
