The last flight I took was in May 2018, so not even a year ago. Before, I was not fully aware of the consequences of aviation – I believe most people are not, and they need to be educated! Not flying and traveling, for instance, from Germany to Spain implies lots of money & time, which is a pain. Yet, it’s all worth it! We need better & cheaper trains systems & more expensive flights!
