Summary Question Answer:
The ocean covers most of Earth and has many different types of life. Coral reefs are very important because they provide homes for sea animals and protect coastlines. However, oceans face serious problems like pollution, overfishing, and climate change. Plastic waste harms marine animals, and too much fishing has reduced fish numbers. Climate change makes water warmer and damages coral reefs. Scientists are working hard to solve these problems by reducing plastic use, creating protected areas, and teaching people about ocean conservation. We need to protect oceans because they are essential for our planet and human survival.
