Healthy oceans = healthy planet

Oceans are vital to the health of our planet, playing a crucial role in regulating the Earth’s climate and supporting diverse ecosystems. Covering more than 70% of the Earth’s surface, oceans absorb and distribute solar energy, helping to moderate global temperatures and weather patterns. They act as a massive carbon sink, absorbing a significant portion of the world’s carbon dioxide emissions, which helps mitigate the impacts of climate change. Additionally, oceans influence weather patterns and precipitation cycles, impacting agriculture and water resources across the globe.

Beyond their climate-regulating functions, oceans are essential for sustaining life and providing economic resources. They support a vast array of marine biodiversity, from the smallest plankton to the largest whales, contributing to the stability of marine ecosystems. Healthy oceans are crucial for fisheries, which provide food and livelihoods for millions of people worldwide. Moreover, oceans offer recreational opportunities and are a source of medicines derived from marine organisms. Protecting ocean health is therefore critical for maintaining ecological balance, supporting human well-being, and ensuring the sustainability of vital resources.
