Protecting One of Tenerife’s Greatest Assets
The programme aims to strengthen public awareness of the importance of Tenerife’s marine environment while encouraging practical action to help protect it.
With oceans playing a crucial role in climate regulation, biodiversity and food security, the initiative highlights how local action can contribute to wider environmental goals.
World Oceans Day serves as a reminder that protecting the sea is not only about conserving wildlife but also about safeguarding the future of island communities that depend on healthy marine ecosystems.
