Flying sucks. Academics are expected to be honoured by the invitation to fly somewhere and talk for free. We spend time traveling for free, we usually get economy seats, we lose work time after the trip to jet lag… all of this time could actually be spent doing research that changes the world. I am an Australian academic. I lose 2 days of my life flying to other side of the world, and another 2 days flying back. Then I am 4 days behind in my other work. The whole idea of academics flying around to deliver presentations or attend meetings is incredibly inefficient – food waste, overwhelming plastic waste. #iflyvegan to try to offset my carbon footprint. I think all academic meetings involving people who have flown in should be vegan events to try to offset the carbon footprint of flying.
