In case you haven't heard, my girlfriends and I have declared the summer of 2012 as the best summer ever. The best way to document said 'best summer ever' is with a good ol' disposable camera. Smile, click, move on! Nobody gets pic approval, and there's no time wasted gathering around the camera to analyze a moment that just happened.
Life is now a war zone, and as such, the number of people considered disposable has grown exponentially, and this includes low income whites, poor minorities, immigrants, the unemployed, the homeless, and a range of people who are viewed as a liability to capital and its endless predatory quest for power and profits.
We imagine going to the moon and planting a flag, going to an asteroid and mining, going to Mars and setting up a colony. And I think that expansionist mentality is very self-destructive, especially given the kind of precarious relationship we now have to the ecosystem here on Earth, because it allows us to imagine that Earth is disposable.
