About

Ocean Pavilion

Features
Read full description

The ocean is our planet’s life-support system and is a critical part of Earth’s climate. It is also a source of hope and holds a wealth of opportunity to help solve many of humanity’s most pressing challenges, including climate change. The Ocean Pavilion is returning to the Blue Zone in Dubai with a fundamental message to COP delegates and attendees: The ocean is fundamental to the planetary systems that regulate our climate, and that delicate balance is increasingly in peril due to human activity. But with careful, science-based solutions and informed policy decisions, the ocean could restore balance and help us chart a path out of our climate crisis.
