Scientists warn of ‘phosphogeddon’ as critical fertiliser shortages loom – By Robin McKie (The Guardian) / Mar 12, 2023
Our planet faces “phosphogeddon”, scientists have warned. They fear our misuse of phosphorus could lead to deadly shortages of fertilisers that would disrupt global food production.
At the same time, phosphate fertiliser washed from fields – together with sewage inputs into rivers, lakes and seas – is giving rise to widespread algal blooms and creating aquatic dead zones that threaten fish stocks.
In addition, overuse of the element is increasing releases of methane across the planet, adding to global heating and the climate crisis caused by carbon emissions, researchers have warned.
“We have reached a critical turning point,” said Prof Phil Haygarth of Lancaster University. “We might be able to turn back but we have really got to pull ourselves together and be an awful lot smarter in the way we use phosphorus. If we don’t, we face a calamity that we have termed ‘phosphogeddon’.”
