In 2023, member states of the United Nations finally agreed on the High Seas Treaty, an international legal framework aimed at placing 30% of the world's international oceans into marine protected areas. This treaty represents a crucial step in managing global marine biodiversity. Previously, ocean conservation was highly fragmented, leaving vast areas of the global ocean vulnerable to unregulated commercial exploitation. Just as heavy industrial decline unintentionally reduced emissions in post-Soviet states, regional declines in local fishing fleets have sometimes allowed fish stocks to recover temporarily, but global demand continues to drive unprecedented pressure on marine habitats.
To address this ecological crisis, some economists advocate for market-based mechanisms. One such framework is the allocation of Individual Transferable Quotas (ITQs) in fisheries, effectively creating tradeable rights to fish. These quotas put a financial value on fishing access, giving operators an incentive to conserve stocks to protect the long-term value of their quota assets. Alongside these regulated markets, voluntary marine conservation credits have emerged, allowing corporations to fund coral reef restoration projects to claim 'biodiversity neutrality'.
However, critics argue that such schemes represent a 'privatisation of the oceans', where wealthy corporate fishing syndicates monopolise quotas, squeezing out small-scale local fishers. Some environmentalists also argue that biodiversity offsets act as a greenwashing tool that fails to address the root causes of habitat destruction.
Crucially, many economists point out that marine pollution and the collapse of migratory fish stocks are worsened by a lack of property rights over the high seas. Because no single nation or entity owns these vast waters, they are treated as free dumping grounds for plastics and industrial run-off. At the same time, individual fishing vessels face a powerful incentive to harvest as much as possible before others do. Without clearly defined and legally enforceable rights, the open ocean remains highly vulnerable to market failure.
Explain what is meant by 'property rights' (Extract B) and analyse how an absence of property rights can worsen the environmental market failures of both ocean pollution and the rapid depletion of marine resources.
