Why is World Ocean Day Important?

The seas of our planet are so much more than vast bodies of water; they are the lifeblood of our planet. Oceans comprise over 70% of the Earth surface, produces more than 50% of our oxygen, and absorb almost 30% of the anthropogenic CO2 released into the atmosphere.  

More than 3 billion people rely on oceans for food, livelihood, and climate mitigation. Therefore, they are often deemed a lifeline.  

However, these intricately connected systems are being pushed to the breaking point of acidification, microplastic pollution, habitat destruction, overfishing, and climate change.

Theme 2025: Sustainable Fishing Means More

World Ocean Day intends to spur action by promoting an annual theme. This year’s theme focuses on sustainable fisheries.   

According to the Marine Stewardship Council (MSC), sustainable fishing promotes fish availability, guarantees the long-term provision of seafood, conserves coastal biodiversity, and facilities the livelihoods of coastal communities. MSC estimates sustainable fisheries can provide an estimated annual increase of 16 million tons of wild seafood production, result in improvements to the environment of over 400%, and provide more consumer choice when it comes to responsible labeling across over 66 countries.  

The Deteriorating Condition of the Ocean

Oceans are enriched, animated, and critical life systems that are threatened with extinction by humans. 

  • Plastic Pollution: At the current rate, about 8 million tons of plastic waste makes its way into the oceans every year. By 2050, that would mean more plastic than fish by weight.  
  • Ocean Acidification: Since the Industrial Revolution, the ocean’s pH value has globally decreased by 0.1 units; that means the ocean has become 30% more acidic. The changes in acidification are happening 50 times faster now and cause such changes in acidification rate that shelled organisms cannot prosper.  
  • Coral Bleaching: Since 2023, most of the reefs have undergone long-term bleaching due to high sea temperature, with about 84% bleaching worldwide.  

In commemoration of World Ocean Day on 8th June, the UN Ocean Conference 2025 commenced in Nice, France under the title “Ocean Wonders”.  To safeguard marine ecosystems, the world's leaders reaffirmed their commitment to protecting 30% of the ocean by 2030 and anticipated more funding.  

The Benefits of Sustainable Fishing

Ecosystems are not the only ones that benefit from sustainable fishing; the seafood industry does as well.  

  • Preserving Biodiversity: Marine ecosystems can bounce back better when overfishing is eliminated and bycatch is reduced. Flexible ecosystems flourish and maximizing a holistic view of ecosystems is beneficial.  
  • Economic Stability: Sustainable fisheries provide stability in income and job security for coastal communities.  
  • Balance of Ecosystem: Healthy fish populations promote and support human nutrition and tourism as well as other species by eating other animals in the food chain.  

Steps You Can Take to Protect Oceans

World Ocean Day encourages everyone to take meaningful, small actions to protect their oceans. Reduce plastic waste, support sustainable fishing practices, consume MSC-certified seafood, participate in local beach clean-ups, and share awareness on social media using the hashtag, #WorldOceanDay. 

World Ocean Day 2025 serves as a reminder that sustainable fishing is about maintaining entire ecosystems, communities, and the future of our world, not only about protecting marine life. Each of us may help create a healthier, more vibrant ocean by making thoughtful decisions.
