As the world continues to grapple with the climate crisis, ocean conservation and marine biodiversity have become central topics on the agenda of the Conference of the Parties (COP). Historically, discussions at COP have focused primarily on reducing carbon emissions and mitigating climate change, but recent years have seen a growing recognition of the vital role oceans play in regulating the planet’s climate and supporting biodiversity. The inclusion of ocean health on the COP agenda signals a crucial shift in global environmental priorities, as healthy oceans are essential not only for climate resilience but also for human well-being and sustainable development.

Oceans cover more than 70% of the Earth's surface and are crucial in regulating the climate by absorbing carbon dioxide (CO2) and heat from the atmosphere. They act as a carbon sink, absorbing about 25% of the CO2 emissions produced by human activities, and over 90% of the excess heat trapped by greenhouse gases. However, this ability is under threat. Increased CO2 absorption is leading to ocean acidification, while rising temperatures are contributing to ocean warming. These changes threaten marine ecosystems, particularly coral reefs, which are vital for biodiversity and coastal protection. Therefore, preserving ocean health is not only about protecting marine life but also about enhancing the planet’s capacity to mitigate climate change.

Marine biodiversity is facing unprecedented challenges due to climate change, pollution, overfishing, and habitat destruction. Coral bleaching, caused by ocean warming, has severely impacted reef ecosystems, which support around 25% of all marine species. The loss of biodiversity in the oceans can destabilize ecosystems, reduce fish stocks, and disrupt livelihoods, particularly for coastal communities that depend on marine resources for food and income. Plastic pollution is another pressing issue, with millions of tons of plastic waste entering the oceans every year, harming marine life and contaminating the food chain.

The COP's focus on ocean conservation highlights the interconnectedness of the climate and biodiversity crises. Protecting marine ecosystems is essential for maintaining the resilience of the oceans and their ability to provide ecosystem services, such as food security, climate regulation, and oxygen production.

To address these challenges, the COP agenda emphasizes several key actions. One of the most urgent priorities is the creation and expansion of Marine Protected Areas (MPAs). MPAs help to conserve critical habitats, restore fish populations, and protect vulnerable species. Currently, only about 7.65% of the world’s oceans are under some form of protection, far short of the target of 30% by 2030, as advocated by marine conservationists. Achieving this goal requires stronger international cooperation and enforcement mechanisms to ensure that these protected areas are effectively managed.

In addition to expanding MPAs, there is a growing emphasis on sustainable fisheries management. Overfishing has depleted fish stocks in many regions, and without significant reforms, the world could face a collapse in global fisheries. The adoption of sustainable practices, such as reducing bycatch, enforcing fishing quotas, and promoting aquaculture, is critical to ensuring the long-term health of marine ecosystems.

The concept of “blue carbon” is also gaining traction at COP discussions. Blue carbon refers to the carbon captured by coastal and marine ecosystems, such as mangroves, seagrasses, and salt marshes. These ecosystems are highly efficient carbon sinks, and their protection and restoration are vital for both biodiversity and climate mitigation. Mangroves, for example, store up to 10 times more carbon per hectare than terrestrial forests. Investing in blue carbon ecosystems not only contributes to climate goals but also provides coastal communities with protection from storms and rising sea levels.

Ocean conservation and marine biodiversity are inseparable from the broader efforts to combat climate change. The inclusion of these topics on the COP agenda reflects a growing awareness of the critical role oceans play in maintaining the health of the planet. Protecting marine ecosystems through the expansion of Marine Protected Areas, sustainable fisheries management, and blue carbon initiatives is essential for the future of both marine life and humanity. As the world continues to face the challenges of climate change, the ocean will remain at the heart of global environmental strategies.
