The average poop is like what, maybe 4 ounces? And the average person poops once a day or so. If we consider all the people living in poorer countries who eat less and poop less, I suppose we could assume that the average person poops an average of 2.85 ounces per day.

At the moment there are approximately 6.381 billion people on the planet. If we multiply the number of people by the weight of the average poop, we come up with 18,185,238,846 ounces, or 1,136,577,430 pounds of poop. Per day.

The people of planet Earth poop over 1 billion pounds of poop each and every day.
