These days, we can see flights that travel far distances using the same fuel as vehicles in the long run; however, the number of greenhouse gases that are emitted by both of them is the same. As a result, a group of people believe instead of limiting using cars, the figure of flights ought to be declined and prevent unnecessary trips like tourist journeys. I do not subscribe to this idea owing to the fact that today, not only time but also the environment is the most important factor, so airlines have to upgrade their planes and governments create fast clean transportation systems.
