Why You Cannot Quarry there and Still “Protect” Pinagrealan Cave
Karst is a type of landscape where the dissolving of the bedrock creates caves, cavities, sinkholes, sinking streams, springs, and similar features.
The area immediately surrounding Pinagrealan Cave contains all of these features:
- Multiple Caves
- Sinking Streams
Spar Development Corporation, under the management of Rosemarie Capa, already destroyed some of the caves and springs. These can never be replaced!
PROTECTING PINAGREALAN MEANS PROTECTING THE ENTIRE AREA FROM QUARRYING!
It is not ONLY Pinagrealan itself which needs protecting – but the entire area.
- It will be too late to say “oops” after Pinagrealan collapses.
- It will be too late to say “sorry” after more of the endemic, endangered, flora and fauna disappear or die.
- It will be too late to say “we didn’t think about it” when the springs dry up.
WHAT IS KARST?
Karst is associated with soluble rock types such as limestone, marble, and gypsum. In general, a typical karst landscape forms when much of the water falling on the surface interacts with and enters the subsurface through cracks, fractures, and holes that have been dissolved into the bedrock. After traveling underground, sometimes for long distances, this water is then discharged from springs, many of which are cave entrances.
PINAGREALAN IS A NON-RENEWABLE RESOURCE
The caves and karst of Pinagrealan Mountain (located in Barangay Bigte, Norzagaray, Bulacan) are significant, non-renewable, geological resources. They are significant in their own historical right and because they house other significant resources including geological resources, paleontological remains, biological resources and cultural resources.
The karst area surrounding Pinagrealan Cave had three other caves, all of which have been reportedly destroyed by the mining operations of Spar Development Corporation. Independent geologists also report that Pinagrealan Cave shows significant damage caused by the quarrying operations of Spar Development Corporation.
The Philippines Government must not allow those who have destroyed the three caves, destroyed the karstic areas of lioness rock, polluted the springs and groundwater of the karst area, and reportedly caused damage to Pinagrealan Cave, to go unpunished.
