this reading is the pollution of flying. in the reading it mentions should people feel the shame of taking the airplane and how can we do to reduce the frequency of people who take fly much more often than others. there is half of American didn’t take airplane but there is also a lot of people take more than 5 times a year which made American become the country to have the highest emission from a passenger in 2018. There is a way mention in the paragraph that made me agree. that give some su[port to those people who didn’t buy the ticket and add some tax to those take fly too frequently. Also for the business using skype is a more sustainable way.
