Celebrating World Oceans Day: The importance of our oceans

Every year on June 8th, the world comes together to celebrate World Oceans Day, a global initiative aimed at raising awareness about the critical role the oceans play in our lives and the urgent need to protect them. This day serves as a reminder of the oceans' vast contributions to human well-being, climate regulation, and biodiversity.

The Vital Role of Oceans

Oceans cover more than 70% of the Earth's surface and are fundamental to life on our planet. They are a key component of the Earth's ecosystem, influencing global weather patterns, absorbing carbon dioxide, and providing a significant source of food and income for millions of people.

Climate Regulation

Oceans play a crucial role in regulating the Earth's climate. They absorb about 30% of the carbon dioxide produced by human activities, which helps mitigate the effects of climate change. Furthermore, they absorb approximately 90% of the excess heat generated by greenhouse gas emissions, thus acting as a buffer against global warming. The ocean's ability to sequester carbon is vital for maintaining the balance of the global carbon cycle and preventing runaway climate change.


Marine ecosystems are incredibly diverse, hosting millions of species, many of which are yet to be discovered. Coral reefs, for example, are among the most diverse ecosystems on the planet, providing habitat and shelter for nearly a quarter of all marine species. The health of these ecosystems is crucial not only for the species that inhabit them but also for human populations that rely on them for food, tourism, and coastal protection.

Economic Importance

The economic value of oceans is immense. According to the World Wildlife Fund, the ocean economy is estimated to be worth $24 trillion, providing jobs and sustenance for millions of people worldwide. Fisheries alone provide over 3 billion people with their primary source of protein and support around 200 million jobs globally. Additionally, the oceans facilitate international trade and transport, with over 90% of the world's goods being transported by sea.

Threats to the Oceans

Despite their importance, oceans are facing unprecedented threats from human activities. Pollution, overfishing, and climate change are some of the major issues that need to be addressed to ensure the sustainability of our oceans.


Marine pollution is a pervasive problem, with over 8 million tons of plastic entering the oceans each year. This pollution not only harms marine life but also affects human health through the consumption of contaminated seafood. Microplastics, in particular, have been found in the digestive systems of marine animals and have the potential to enter the human food chain.


Overfishing is another significant threat, with approximately 34% of the world's fish stocks being overexploited as of 2020, according to the Food and Agriculture Organization (FAO). This unsustainable practice not only depletes fish populations but also disrupts the balance of marine ecosystems and threatens the livelihoods of communities that depend on fishing.

Climate Change

The impacts of climate change on the oceans are profound. Rising sea temperatures, ocean acidification, and sea level rise are altering marine habitats and threatening the survival of many species. Coral reefs, for instance, are particularly vulnerable, with large sections experiencing bleaching events due to increased water temperatures.

Efforts to Protect the Oceans

On World Oceans Day, individuals, organisations, and governments are encouraged to take action to protect the oceans. This includes participating in beach cleanups, reducing plastic use, supporting sustainable seafood, and advocating for policies that promote ocean conservation.

International Agreements

International cooperation is essential for the protection of the oceans. Agreements such as the United Nations Convention on the Law of the Sea (UNCLOS) and initiatives like the Sustainable Development Goals (SDGs) highlight the global commitment to preserving marine environments. SDG 14, for instance, aims to "conserve and sustainably use the oceans, seas, and marine resources for sustainable development."

Marine Protected Areas

Establishing Marine Protected Areas (MPAs) is a key strategy for conserving marine biodiversity. MPAs restrict human activity in critical habitats, allowing ecosystems to recover and thrive. As of 2021, about 7.7% of the world's oceans were designated as MPAs, with goals to increase this to 10% by 2020 as part of the Aichi Biodiversity Targets, though efforts are ongoing to reach and surpass this target.

World Oceans Day is a crucial opportunity to recognise the importance of our oceans and the urgent need to protect them. By understanding the critical role oceans play in our lives and the threats they face, we can take informed actions to ensure their health and sustainability for future generations. Protecting our oceans is not just an environmental necessity but a fundamental component of human survival and prosperity.

This article beautifully highlights the interconnectedness of our global society with the health and preservation of our oceans. How ? :

1. Global awareness and collaboration: World Oceans Day is a global initiative that brings people from all corners of the world together to celebrate and raise awareness about the oceans' importance. This demonstrates how people from diverse backgrounds unite for a common cause, reflecting the interconnected nature of our global society.

2. Environmental stewardship: The article emphasizes the critical role oceans play in maintaining life on Earth and mitigating climate change. This underscores the collective responsibility of individuals, organizations, and governments worldwide to protect and preserve the oceans for future generations, showcasing a commitment to global environmental stewardship.

3. Socio-economic impact: The oceans are not only essential for environmental sustainability but also crucial for economic prosperity. The article highlights the economic significance of oceans, including their contribution to global trade, food security, and employment. This underscores how protecting the oceans is not just an environmental issue but also a socio-economic imperative that affects people's livelihoods worldwide.

4. International cooperation: Efforts to protect the oceans require international cooperation and collaboration. The article mentions international agreements such as the United Nations Convention on the Law of the Sea (UNCLOS) and initiatives like the Sustainable Development Goals (SDGs), illustrating how countries come together to address common challenges and work towards shared goals for ocean conservation.

5. Individual and collective action: The article encourages individuals, organizations, and governments to take action to protect the oceans, emphasizing the collective responsibility we all share in safeguarding this vital resource. This highlights the power of collective action and community engagement in addressing global challenges, including the protection of the oceans.
