In the past 100 years, there are many inventions such as antibiotics, airplanes, and computers. What do you think is the most important invent for the past 100 years? Why?
With the continuous evolution of the first class services, some people may think that the airplane companies neglected the advantages of other passengers. In my opinion, while first-class passengers certainly enjoy premium service, most advances benefit all passengers.
Air travel is responsible for a lot of pollution in our environment. Some people think that prices of airplane tickets should be increased in order to reduce air traffic.
Do you agree or disagree?
Airplane uses more fuel and causes more pollution than car do. In such a case non-essential air travel should be discouraged in order to make the environment better rather than limiting the car use to what extend do you agree.
