Planet Ocean: tides are changing
The ocean covers over 70% of the planet. It is our life source, supporting humanity’s sustenance and that of every other organism on earth.
The ocean produces at least 50% of the planet’s oxygen, it is home to most of earth’s biodiversity, and is the main source of protein for more than a billion people around the world. Not to mention, the ocean is key to our economy with an estimated 40 million people being employed by ocean-based industries by 2030.
Even though all its benefits, the ocean is now in need of support.
With 90% of big fish populations depleted, and 50% of coral reefs destroyed, we are taking more from the ocean than can be replenished. We need to work together to create a new balance with the ocean that no longer depletes its bounty but instead restores its vibrancy and brings it new life.
“Planet Ocean: tides are changing”, is the theme for World Oceans Day 2023 – the UN is joining forces with decision-makers, indigenous leaders, scientists, private sector executives, civil society, celebrities, and youth activist to put the ocean first.

Alors que plus personne aujourd’hui ne songe à remettre en cause l’importance de la diversité biologique pour le présent et pour les générations futures, certaines activités humaines continuent pourtant à réduire le nombre d’espèces vivantes: agriculture intensive et épandages massifs de produits phytosanitaires, pêche intensive et élevage industriel, chasse d’éspèces protégées, déforestation, etc…

Mangroves are rare, spectacular and prolific ecosystems on the boundary between land and sea. They ensure food security for local communities. They provide biomass, forest products and sustain fisheries. They contribute to the protection of coastlines. They help mitigate the effects of climate change and extreme weather events.
