So, apparently, 70 millions of Indonesians are still disposing their human waste in an unsafe manner, that is directly to the environment. Let’s do rough calculation: with the assumption of 200 grams (0.44 lb) of waste produced in average daily by a person, that means around 14,000 tons (30,8 million lb) of feces is seeping to the soil -and eventually to ground water, streams, rivers, lakes, beaches.

But what is 14,000 tons of feces like? Let’s do again a rough calculation: with the assumption of the weight of a Sumatran elephant is 3 tons, (and the specific weight of feces and the elephant is the same), that means, each day there are 4,666 Sumatran elephant made of feces wondering around , i mean sipping into, the soil and the water bodies.

How about urine? In average, we produce 1.5 liter (50 fl oz, or 6.3 cups) daily. Let’s do again the rough calculation: with the assumption of an Olympic-size swimming pool has a dimension of (50 x 25 x 2) m3, that means the Indonesians are pouring 42 Olympic-size-swimming-pool worth of urine, daily, in their own beautiful islands and rich environment.
