The Background

The end of the world wasn't planned, but everyone saw it coming. All of humanity had heard the news reports and stories about the polution we, as a species, were inflicting on the world, but we simply turned away and ignored it. And then it tapped our shoulder and showed us what a huge mistake we had made. Disease running rampant, air quality dwindiling, and still people saw this as an opportunity to make money. In a rush to save humanity, scientist developed a purification system to clean the air and called them Nets. These Nets were set up around large city's, and things were good. But the nets couldn't cover everything, and eventually city's began to overpopulate. It was decided that only people that could pay could stay, and everyone not rich enough to pay the taxes on life were shoved back outside and into the Background. This is what becomes of humanity.
