AS the world celebrates World Toilet Day today, sanitation experts have called for the end of the flushing dunny to save water and provide fertilizer for crops.
Leading health advocates have called for the use of "dry" toilets which separate urine from faeces and remove the need to flush.
Mr Sims said a culture where people flushed their loos but disregarded the thousands of litres of wasted drinking water each year was one of sanitation's greatest challenges.
"This 'flush and forget' attitude creates a new problem which we have to revisit," he said.
Personally, I prefer the 'flush and forget' attitude.... Can you believe this... umm... mess? :-D
