Boracay bay in the Philippines is reportedly turning green, due to untreated 'waste water'.
An environmental study identified the problem in 2015, a waste pipe releasing untreated water near the shore.
According to GMA news, locals have claimed the algae is an annual phenomenon.
Algae is a problem on east Asia's coastlines, regularly affecting China.
Yet scientists believe it is a tell tale sign of pollution.
Photos taken on Sunday reveal the extent of the problem.
Residents say the algae eventually disappears during the summer months. https://t.co/c6FbicjKPA — Chino Gaston (@Chino Gaston)
The waste is causing a sludgy algae to develop on the surface of the water.
