On average, a human produces about 0.5 to 1.5 liters (or roughly 0.13 to 0.4 gallons) of urine and 100 to 250 grams (0.22 to 0.55 pounds) of feces per day, depending on factors like diet, hydration, and individual physiology. Globally, with a population of approximately 8 billion people, this translates to an estimated 4 to 12 billion liters of urine and 800,000 to 2,000,000 metric tons of feces generated daily.
