think about toilets

According to UN water statistics, conventional flush toilets in middle-class households account for approximately 30 percent of global water use. The average daily water use per person among middle-class populations is about 200 liters, although in some countries the volume is larger. (In the United States, for example, it is 380 liters per person.) Thus, on average, each middle-class person uses 60 liters of fresh water per day to flush their urine and feces down the drain. Considering that there are almost 7 billion people on earth (expected to reach 9 billion by 2050) and that only .75 percent of the world’s water is fresh, is it reasonable to use this water to flush toilets?
