A few months ago I wondered if there is a right age to be a graduate student. However, as my fellow blogger Sophie reminds us here and here, each of us is more than a student, and there are other things in our lives beside being a student here and now: Family, friends, sports, art, views… and what about the idea of saving the world?

Well, maybe that’s too much. Or, I should say, that is not an expression I completely approve, because when we talk about saving the world most of the times what we actually mean is preventing ourselves from making things further worse, for example by not further increasing pollution, not further widening the gap between the rich and the poor, or not adding another war to human history. Things that we should do anyway to be good citizens of the world, but that we like associating with the heroic expression saving the world, because apparently we are more likely to do what we believe is right, if doing it makes us feel a bit of a hero. So, in most cases, the expression saving the world is an overstatement… but hey, if it motivates us, let’s go for it! Let’s use this expression, let’s think about saving the world!

For me, saving the world is one of those concepts that come up every now and then, when I hear the story of someone who is actually doing it, or who has done it in the past. This happened again a few weeks ago, when my social media networks started talking about Greta Thunberg.
