As Earth’s climate changes, scientists and environmental projects are increasingly exploring how oceans can help maintain atmospheric balance by capturing excess carbon dioxide (CO₂).
What’s happening?
Many research teams and startups are currently testing various approaches to enhance the ocean’s natural ability to absorb CO₂. One such method is increasing the alkalinity of water, allowing carbon dioxide to bind and transform into safe forms.
🔹 In Canada, for example, the company Planetary Technologies is adding magnesium oxide to the waters of Halifax Harbor. This helps the water absorb CO₂ without harming the environment.
🔹 Other methods include submerging specific rocks, adding minerals, or growing seaweed, which actively absorbs CO₂ as it grows.
Why does this matter?
The ocean is a natural system that already absorbs about 30% of all atmospheric carbon dioxide. But with climate change, its ability to do so may diminish. That’s why it’s crucial to find gentle and sustainable ways to strengthen its natural functions.
Are there any risks?
While initial tests suggest minimal risk, scientists urge caution:
• How will this affect marine life?
• Will the salinity or acidity of the water change?
• Are coastal communities prepared to engage in such projects?
Some programs have already faced skepticism and protests, highlighting the importance of transparency, public involvement, and inclusive dialogue.
The ocean carbon credit market is emerging: companies fund CO₂ removal projects and receive climate “bonuses” in return. But scientists stress that this is only one of many tools, and not a replacement for the broader ecological transition.
The ocean is not just a tool — it is a living partner in restoring planetary balance. When we act in harmony with nature — rather than against it — we create the possibility of a sustainable future, where every element, including the ocean, resonates in the unified rhythm of Life.
