Interesting fact:

Do you have an idea of which airports are the most frequented in the world? Dubai, London and Hong Kong had more than 70 million passengers taking off in planes from their landing strips during 2017. This is the more or less the population of Thailand!! Here’s something to think about: every minute there is a flight travelling somewhere in the sky. Are we taking too many flights? Maybe we should start using our legs more to travel, like we used to in the past.
