On June 8th, we celebrate World Oceans Day under the global theme: “Wonder: Sustaining What Sustains Us.” The ocean covers 70% of the Earth’s surface and is not only vast but vital for the existence of life. According to the United Nations News, the ocean produces over 50% of the planet’s oxygen, absorbs 25% of human-generated carbon dioxide, and regulates climate patterns critical to life.
Wonders Beneath the Ocean Waves
Beyond threats, the ocean harbors breathtaking wonders. Scientists estimate that over 80% of the ocean remains unexplored, according to National Geographic. Another beautiful wonder is that the Mariana Trench plunges deeper than Mount Everest is tall and is filled with a host of mysterious and unique sea creatures.
Coral reefs, often called the “rainforests of the sea,” support 25% of marine life despite covering less than 1% of the ocean floor. Even more astonishing, the largest migration on Earth occurs daily as deep-sea creatures rise to the surface under cover of night to make their way to other areas. These are some of the beautiful wonders that require our mindfulness and protection and of course changed habits.
The Ocean: A Critical Lifeline Under Threat
Despite its importance, the ocean is under unprecedented stress and the UN Trade & Development reports that nearly 90% of global fish stocks are exploited or depleted. Coupled with this sea surface temperatures have risen by nearly 1°C since pre-industrial times, contributing to coral bleaching events and extreme weather.
Pollution is another grave concern. According to the World Economic Forum, 6 million metric tons of plastic leak into the rivers and coastlines every year. Without intervention, this figure could triple by 2040. Meanwhile, the Ellen MacArthur Foundation warns that by 2050, plastics could outweigh fish in the oceans.
Three Ways We Can Sustain What Sustains Us – Our Ocean
While the ocean is a filled with mysteries, wonder must fuel our action. Here are three actions we can take for its sustainability:
-
Cut Plastic at the Source
It is essential that collectively we push for policies that drastically reduce plastic production and scale up advanced waste management. The fact is every piece of plastic avoided is one less threat to marine life and ocean health.
-
Scale Up Ocean Sanctuaries
According to the World Resources Institute, protected waters deliver returns up to ten times greater by reviving biodiversity, boosting fisheries, and strengthening coastal resilience, so expanding marine protected areas is an investment.
-
Harness the Power of Blue Carbon
Mangroves, seagrasses, and salt marshes are all nature’s climate warriors and their restoration is essential for our survival. These ecosystems can sequester carbon up to 35 times faster than tropical rainforests, according to Conservation International, locking away carbon while shielding coastlines from rising seas.
As we marvel at the ocean’s mysteries and vast wonders, World Oceans Day is a reminder that sustaining what sustains us is not optional, its essential for our survival. al and will ensure that the ocean’s wonder endure for generations to come.
