Scientists warn of ‘phosphogeddon’ as critical fertiliser shortages loom

Excessive use of phosphorus is depleting reserves vital to global food production, while also adding to the climate crisis

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.
