Understanding the Ocean's Role and Challenges

The video emphasizes the ocean's critical role in sustaining life by providing oxygen, regulating climate, and supporting the water cycle. It highlights technological advancements that have improved our understanding and exploration of the ocean. However, it also warns of the significant decline in coral reefs and fish populations due to human activities, stressing the need for urgent action to restore ocean health.

What is one of the primary roles of the ocean in supporting life on Earth?
