People travel mostly by airline, and some people prefer not to fly at all. There have been negative environmental pollution effects caused by Airplanes flying most often. But we should not unforeseen the economical contribution of Airlines business and the value of money they add.
In recent years, people avoid traveling by airlines because they produce highest level of carbon emission which is major cause of produce air pollution. Therefore, by reducing flight will decrease risk of air pollution and reduce the risk of effects on human health. These days global warming is so much more important as there has been large industries which contribute to environmental pollution and airlines business are one of them.
On the other hand, Airplane business will severely impact if people avoid fly. Because it is one of the largest contributors for economy. There are also some advantages of flying likewise, reaching destination more quickly, traveling from one country to another country. Also, there are many businesses that rely on airlines business like hotels, tourism sectors, because some destinations can only be travel by air like some hill station side. There will also be financial loss for companies management and many people lose their jobs.
In my view, there will be short-term losses for airlines companies because, they will find ways to convert their model of earnings and go with less carbon emissions aircraft, or some hybrid airplanes will be introduced. But in long term environmental benefits are more important because climate changes are severely impacting human health if avoiding airplanes reduce it then we should avoid fly in not necessarily.
