On October 26, 2025, the tailing pond of the URC Bais Distillery collapsed. As a result, thousands of cubic meters of molasses wastewater spilled into the Tañon Strait. This spill polluted over 3,000 hectares of marine waters between Negros Oriental and Cebu. The spill killed fish and discolored the water. It forced tourism operators in Bais and Manjuyod to suspend dolphin-watching and sandbar activities. What unfolded was more than an ecological crisis. It was an economic crisis as well. This crisis rippled through coastal communities. Their livelihoods depend on clean water, healthy fish stocks, and tourism income. Yet, despite the extent of the damage, there has been no official economic valuation. Without valuation, harm remains visible to the eye but invisible to the law.
Economic valuation is not about assigning a price to nature. It is about recognizing the real value of ecosystem services that sustain livelihoods and well-being. It transforms abstract losses into measurable, actionable data that policymakers and courts can use to demand accountability and rehabilitation. In the absence of valuation, justice often fails to materialize. The Clean Water Act requires the government to quantify and integrate environmental costs into planning and policy. The Philippine Ecosystem and Natural Capital Accounting System (PENCAS) Act also imposes this duty. However, in many cases these studies are never conducted. As a result, environmental disasters become administrative events instead of economic wrongs.
This failure is not theoretical. In the case of Ang Aroroy ay Alagaan, Inc. v. Filminera Resources Corp., environmental advocates in Masbate filed a petition. They aimed to stop gold mining operations. These operations were alleged to have caused water pollution and marine degradation. The case was dismissed. The petitioners did not provide scientific evidence linking the mining activity to the harm. They also failed to provide valuation evidence. The courts held that while the right to a balanced and healthful ecology is self-executory, it cannot rest on speculation. Without measurable data, there was no causal proof, and therefore no justice. This shows that when environmental damage is not quantified, the legal system has nothing to compensate. It has no foundation to impose liability. There is also no guide to direct restoration.
The law, however, provides a way to act amid scientific uncertainty through the precautionary principle. This principle is enshrined in Rule 20, Section 1 of the Rules of Procedure for Environmental Cases. It allows courts to act even when causation is not fully proven. It shifts the burden of proof to the polluter once a prima facie case of environmental risk is shown. In the landmark case Resident Marine Mammals of the Tañon Strait v. Reyes, the Supreme Court ruled that complete scientific certainty is unnecessary. Action should not be postponed if it can prevent environmental harm. In practice, however, the Filminera case demonstrates that courts hesitate to apply this principle. This happens when there is no baseline data or valuation study to demonstrate measurable harm. The absence of valuation deprives the precautionary principle of its factual footing.
In the URC Bais Distillery spill, the Environmental Management Bureau itself confirmed the contamination of thousands of hectares. They also confirmed the presence of fish kills and the closure of tourism activities. These are not speculative claims—they are facts. The prima facie case for environmental harm already exists. Therefore, failing to conduct an economic valuation at this stage runs counter to the very spirit of the precautionary principle. The principle demands preventive and remedial action even amid uncertainty, and valuation is the mechanism that gives it economic expression. Quantifying losses in fisheries, tourism, and household costs is necessary not just to demand accountability. Estimating non-market ecosystem values is also essential to guide rehabilitation and compensation.
When valuation is absent, the government cannot compute what justice demands. Victims receive no restitution, ecosystems receive no quantified restoration, and polluters face no cost proportional to the damage they cause. Without numbers, there are no remedies. Without valuation, there is no justice. And without accountability, pollution becomes merely another cost of doing business. The precautionary principle tells us to act before harm becomes irreversible. For that action to have meaning, it must be backed by measurement.
The Tañon Strait is not just a channel between two islands. It is a living system that feeds communities. It attracts tourism and anchors the regional economy. Its value is not speculative but measurable. Government agencies such as DENR, NEDA, BFAR, and local governments have a duty. They must translate this value into policy through formal economic valuation. Only then can we ensure that environmental protection is not symbolic but substantial. The spill in Bais should be a turning point. It should teach us that when damage has no price, accountability disappears. To value nature is to defend it. To measure loss is to make justice possible.
To value nature is not to commercialize it but to defend it. Measurement gives law and policy their moral weight. When damage has no price, accountability disappears. But when we count every lost fish, canceled tour, and poisoned tide, we remind the nation that ecology is economy. Justice begins with knowing what we have truly lost.
