I work in global health and lead a project in Bangladesh. Most of my colleagues fly a lot and consider this normal. I try to minimize my flying. This means declining invitations or participating remotely (often the organizers don’t put enough effort to make it work well, though), going to conferences when they are in Europe where I can take the train, and relying on collaborators and colleagues in Bangladesh.

My postdocs and PhD students still fly more and I don’t pressure them too much, as they want to build their careers.
