To conclude, for me sustainability is first and foremost a cultural problem, and we can solve it only through a profound cultural change. Now this is the core of my PhD so, for the sake of everyone here, I will not dig into that, it would be long and tedious and not without major debates.
My dissertation doesn't write itself and my clients' graphics don't design themselves (AI crowd don't dare answer this) so I'll end it here.
Be nice to each other, we need to come together for this fight.
