Oceans cover 71 percent of the Earth's surface, earning it the name Blue Planet. Acting as powerful carbon sinks, they absorb 20-30 percent of human-emitted carbon dioxide and feed nearly 3 billion people worldwide.
From the crystal-clear waters off Spain and Sardinia to the vibrant reefs of Koh Rong in Cambodia, these seas have shaped the way I see our world. Each swim among colorful fish and deep turquoise hues reminds me of how connected we all are through this vast blue expanse.
Deep-sea wildlife underpins these vital functions. By locking away carbon and supporting marine food systems, every creature in the abyss plays a role in stabilizing our climate and sustaining communities.
If deep-sea communities falter, the ocean's capacity to act as the planet's lungs could weaken, putting both climate balance and food security at risk.
In early June 2025, the UN Ocean Conference in France reinforced that these blue lungs are a common heritage of humanity. Simple choices (like reducing carbon emissions and championing ocean science) can help protect the hidden heart of our Blue Planet.
