A total of 4000 kilos of assorted waste materials were seized by the Estero Rangers in Quezon city as reported by the Department of Environment and Natural Resources on Thursday.

The continuous cleanup drive being conducted by a group of volunteers and other groups is in line with the ongoing rehabilitation of Manila Bay.

The DENR Metropolitan Environmental Office-East and the Department of Sanitation-Rivers Cleaning Operations Group of Quezon City conducted a joint cleanup of a portion of Marikina River in Barangay Old Balara in Quezon City.

The Estero Rangers assigned in the area together with the officials and staff of Barangay Old Balara joined hands in the removal of 300 sacks of assorted waste weighing an estimated 4,000 kilograms.

The clean-up drive coincided with the International Day of Clean Air for Blue Skies last Wednesday, a day designated by the United Nations General Assembly to encourage efforts to improve air quality, protect human health and mitigate the impact of climate change.

The theme "The Air We Share" highlighted the transboundary nature of air pollution and stresses the need for collective accountability and action.

It also focuses on the need for immediate and strategic international and regional cooperation for more efficient implementation of mitigation policies and actions to tackle air pollution.
