There are many strong arguments to be made in favour of any measure aimed at increasing environmental protection, yet imposing limitations on flights may not be the best solution, as will now be discussed.
Primarily, although air pollution is a significant factor, reducing travel by air would not necessarily reduce travel. Instead, people would likely rely even more on motor vehicles, even for longer journeys. This could actually lead to higher rates of pollution. To illustrate, it could potential takeover 300 private to transport the same number of passengers as can be carried on one flight.
Another issue to be considered is that air travel, although undertaken for many reasons, is a common method of transportation for business people. Reducing the number of flights may result in fewer business trips, which could then lead to less business, especially at an international level. Although this may be advantageous for the environment in the short term, it would not be a positive move for the global economy in the long term.
However, it could be argued that reducing flights may encourage business to be transacted in different ways, especially with increasing technologies. Yet this must be balanced with the environmental impact of discarded and obsolete communication devices, which could potential pose an equal r greater ecological risk.
