Nobody exists in a vacuum - no decision affects only yourself. The world is dying from 1,000,000,000 little cuts in the form of all the little decisions we make that we think don't matter. It's overwhelming, I know. We all just want to ignore it, but that's exactly the mentality that's causing it in the first place. We all have to do everything for everyone - not for ourselves - no matter how hard it is. I'm sorry.
