The United Nations is to issue a call for the world to stop simply throwing sewage away, arguing that it is economically valuable and warning that fresh water is a finite resource.
More than 80 per cent of the world’s wastewater is currently discharged into the environment untreated, causing diseases that kill 842,000 people every year, including about 300,000 children under the age of five.
Blooms of algae, which grow rapidly in sewage-rich sea water, have also created vast ‘dead zones’ where most marine life cannot survive. And less fish in the sea means less food for humans at a time when the global population is climbing rapidly.
