Marine exploration is the study and investigation of the ocean and its ecosystems. Scientists and researchers use various tools, such as submarines and underwater robots, to explore the depths of the sea. This exploration helps us understand marine life, including unique species like coral reefs and deep-sea fish, and the impact of human activities on these environments. Through marine exploration, we also discover valuable resources, such as oil and minerals, and learn about the ocean's role in regulating the Earth's climate. By studying the ocean, we can better protect its ecosystems and ensure a sustainable future for both marine life and humanity.
