What do you think are some of the root causes of apathy in our society?
Personally, I'd say that as long as something doesn't directly affect me (at a micro level) and / or I lack a strong means of controlling the outcome, my response to it is going to be apathetic. That said, my stance towards the possibility of improving something with efforts and concern from its existing state would be more of reluctance than in a scenario where the situation worsens from its current state.
You're going to have to be a little more specific or provide us some context here. In what realm of society are you witnessing apathy? The causes can change depending on the context.
