Suatu kasus yang apabila di diamkan , di cuek-in akan membawa malapetaka 
bagi kemanusiaan. Manusia yang sekarang mencapai jumlah 6 milyard orang lebih 
akan memberatkan planit bumi.
    Diberikan satu contoh, keluarga ber-anggotakan 5 orang akan memerlukan 150 
000 liter air untuk menggelontor toilet setiap tahunnya.
   
  Contaminasi yang dibebankan atas kesalahan manusia sendiri achirnya akan 
mencelakan kelestarian manusia dan alam sekelilingnya.
   
  Dalam kunjunganku yang terachir tahun lalu mulai aku pikirkan bagaimana itu 
pengolahan wste yang diprodusir oleh penduduk Jakarta yang mencapai jutaan 
orang. Sangat mengerikan kendala sampah yang di "produsir" oleh penduduk 
Jakarta.
   
  Apakah ada teman2 disini yang tahu, terutama di Swedia , Amerika dan China 
soal apa yang disebut dalam tulisan dibawah ini sebagai..."dry toilet"? Inilah 
kiranya yang paling baik di terapkan untuk menyelamatkan kemanusiaan dari 
uruk-an kotoran yang diproduksinya sendiri.

Pottytraining the World       
By Lester Brown | Monday, October 01, 2007     With the global population 
surpassing 6.7 billion and emerging economies consuming greater amounts of 
natural resources, water is becoming increasingly scarce. Lester Brown 
advocates a practical way in which people can take matters into their own hands 
and clean up their environmental act. 
  In urban settings, the one-time use of water to disperse human and industrial 
wastes is becoming an outmoded practice, made obsolete by new technologies and 
water shortages.     Water enters a city, becomes contaminated with human and 
industrial wastes, and leaves the city dangerously polluted. Toxic industrial 
wastes discharged into rivers and lakes or into wells also permeate aquifers, 
making water — both surface and underground — unsafe for 
drinking.       Better waste management    And their                     The 
existing water-based waste disposal economy is not viable. There are too many 
households, factories and feedlots to simply try and wash waste away on our 
crowded planet.    toxic wastes are destroying marine ecosystems, including 
local fisheries.     The time has come to manage waste without discharging it 
into the local environment, allowing water to be recycled indefinitely — 
and reducing both urban and industrial demand dramatically.
     The current engineering concept for dealing with human waste is to use 
vast quantities of water to wash it away, preferably into a sewer system where 
it will be treated before being discharged into the local river.       Harmful 
consequences    The “flush and forget” system is expensive, 
water-intensive, disrupts the nutrient cycle — and is a major source of 
disease in developing countries.     As water scarcity spreads, the viability 
of water-based sewage systems will diminish. Water-based sewage systems take 
nutrients originating in the soil and typically dump them into rivers, lakes or 
the sea.       Killing natural resources    Not only                     
Fortunately, there is a low-cost alternative — the composting toilet. 
This is a simple, waterless, odorless toilet linked to a small compost 
facility.    are the nutrients lost from agriculture, but the nutrient overload 
has led to the death of many rivers and to the formation of some
 200 dead zones in ocean coastal regions. Sewer systems that dump untreated 
sewage into rivers and streams are a major source of disease and death.     
Sunita Narain of the Centre for Science and Environment in India argues 
convincingly that a water-based disposal system with sewage treatment 
facilities is neither environmentally nor economically viable for India.     
She notes that an Indian family of five, producing 250 liters of excrement in a 
year and using a water flush toilet, requires 150,000 liters of water to wash 
away its wastes.       Spreading germs    As currently designed, India’s 
sewer system is actually a pathogen-dispersal system. It takes a small quantity 
of contaminated material — and uses it to make vast quantities of water 
unfit for human use, often simply discharging it into nearby rivers or streams. 
Narain says both “our rivers and our children are dying.”     
India’s government, like that of many other developing
 countries, is hopelessly chasing the goal of universal water-based sewage 
systems and sewage treatment facilities — unable to close the huge gap 
between services needed and provided, but unwilling to admit that it is not an 
economically viable option. Narain concludes that the “flush and 
forget” approach is not working.       A new approach    This dispersal 
of pathogens is a huge public health challenge. Worldwide, poor sanitation and 
personal hygiene claim                     The “flush and forget” 
system is expensive, water-intensive, disrupts the nutrient cycle — and 
is a major source of disease in developing countries.    2.7 million lives per 
year, second only to the 5.9 million claimed by hunger and malnutrition.     
Fortunately, there is a low-cost alternative — the composting toilet. 
This is a simple, waterless, odorless toilet linked to a small compost 
facility. Table waste can also be incorporated into the composter. 
    The dry composting converts human fecal material into a soil-like humus, 
which is essentially odorless and is scarcely 10% of the original volume. These 
compost facilities need to be emptied every year or so, depending on design and 
size.       Manifold purpose    Vendors periodically collect the humus and can 
market it as a soil supplement, thus ensuring that the nutrients and organic 
matter return to the soil, reducing the need for fertilizer.     This 
technology reduces residential water use, thus cutting water bills and lowering 
the energy needed to pump and purify water. As a bonus, it also reduces garbage 
flow if table waste is incorporated, eliminates the sewage water disposal 
problem and restores the nutrient cycle.       Pioneering use    The U.S. 
Environmental Protection Agency now lists several brands of dry toilets 
approved for use. Pioneered in Sweden,                     Sewer systems that 
dump untreated sewage into rivers and streams are a major source of
 disease and death.    these toilets work well under the widely varying 
conditions where they are now used, including Swedish apartment buildings, U.S. 
private residences and Chinese villages.     At the household level, water can 
be saved by using showerheads, flush toilets, dishwashers, clothes washers and 
other appliances that are more water-efficient. Some countries are adopting 
water efficiency standards and labeling for appliances, much as has been done 
for energy efficiency.     When water costs rise, as they inevitably will, 
investments in composting toilets and more water-efficient household appliances 
will become increasingly attractive to individual homeowners.       Other 
methods    For cities, the most effective single step to raise water 
productivity is to adopt a comprehensive water treatment/recycling system, 
reusing the same water continuously.     With this system, only a small 
percentage of water is lost to evaporation each time it cycles through. Given
 the technologies that are available today, it is quite possible to recycle 
urban water supplies comprehensively, largely removing cities as a claimant on 
scarce water resources.     The existing water-based waste disposal economy is 
not viable. There are too many households, factories and feedlots to simply try 
and wash waste away on our crowded planet. To do so is ecologically mindless 
and outdated — an approach that belongs to an age when there were many 
fewer people and far less economic activity.
