A lakeshore resident cleans up his jurisdiction of decaying algae that has brought a disturbing stench to the residents in Laguna Lake’s nearby Barangay Bayanan in Muntinlupa on Friday. Officials say algae bloom yearly in Laguna Lake due to the heat brought by summer, and the decaying algae have emitted a foul smell that fish pen owners believe may affect oxygen level and cause possible fishkill to nearby fish pens.
