The worst part of apathy is that it rarely stays that way and when it finally decides to fade, and when we begin to care, it's usually not for good reasons.
Apathy creates reactionary living, and the reaction is usually to something negative, a perceived threat even.
So, in order to get people to care, there will be more negativity, and perceived threats even.
Start caring before you have to.
Try to be passionate about keeping things the way you like them, or even making them better, instead of just preventing all hell from breaking lose.
