World Oceans Day: preserving what sustains us

An ecosystem that provides us with many benefits, the oceans play an important role in the existence of living beings, which is why today, in 2025, we are calling for reflection on their care and protection.

Under the slogan: Ocean Wonders: Conserving what sustains us, the global scientific community urges us on June 8th to become aware of and reconnect with the essence of our planet: the oceans, that blue immensity that covers more than 70 percent of the Earth.

Undoubtedly, the sustenance and source of life for all living beings and other organisms on Earth, which we must protect, warn experts.

Although it may seem incredible, we tend to underestimate the magnitude of the ocean’s role in our existence, since the production of at least half of the oxygen we breathe depends on it, it is home to most of our planet’s biodiversity and is the main source of protein for more than a billion people.

Its importance even extends to the global economy, with projections estimating some 40 million jobs linked to the ocean sector by 2030.

From climate regulation to the provision of food and livelihoods, the oceans are the true pillars that support humanity and life on Earth.

Yet, despite their immense benefits, our oceans are facing unprecedented pressure, warns a UN statement on the occasion.

The data are alarming, 90 percent of large marine fish species have declined dramatically, and half of coral reefs, vibrant epicenters of biodiversity, have already been destroyed.

We are extracting resources from the ocean at a rate that far exceeds its capacity to recover. This unsustainable dynamic has brought us to a critical point where exploitation threatens to deplete what sustains us, they warn.

For scientists, the need for change is imperative and we must forge a new balance, one in which we stop seeing the ocean as an inexhaustible source of resources and begin to recognize it as a vital ecosystem that requires our protection and restoration.

The goal is clear: to restore its vitality, its capacity for regeneration and its majesty, they say.

In fact, starting tomorrow, the Oceans Conference will be held in the city of Nice, France, where governments, organizations, financial institutions, academia, the private sector and civil society will meet to find solutions for the conservation and correct and sustainable use of the oceans.
