For users of water-based sanitation, most of us give little thought to what happens after we hear the sound of the toilet flushing. Wooooosh -- out of sight, out of mind.
Certainly, there is massive benefit to be derived from owning and using a functioning toilet.
But what if you were told that there is nothing at the end of the sewage pipe that actually deals with what flows down the toilet? What if you learned that every flush pollutes the environment, and that combined with the chemicals, heavy metals and nutrients from industrial pollution and agricultural run-off, the improperly treated waste was turning rivers, lakes and estuaries into dead zones? Would you think twice next time you flushed?
