The ocean is a vast body of saltwater that covers more than 70% of the Earth's surface. It is crucial to the planet's ecosystem, playing a key role in regulating climate, weather patterns, and oxygen levels. The ocean is home to a diverse array of marine life, from the tiniest microscopic organisms to the largest whales. It is also a source of food, energy, and resources for humans, supporting industries such as fishing, shipping, and tourism. Despite its importance, the ocean faces numerous threats, including pollution, overfishing, and climate change, making conservation efforts crucial for its preservation.
