The sea is a vast body of saltwater that covers more than 70% of the Earth's surface. It is home to a diverse range of life, from tiny plankton to massive whales. The sea plays a crucial role in regulating the planet's climate and provides resources like fish and seaweed for human consumption. People enjoy the sea for various activities, such as swimming, surfing, and sailing. Coastal areas often feature beautiful beaches where families can relax and have fun. The sea also inspires art and literature, with many famous works celebrating its beauty and mystery, like Herman Melville's "Moby Dick."
