Oceans cover more than 70% of the Earth's surface, making them the largest habitat on the planet. They are home to a vast array of plants and animals, from microscopic plankton to massive blue whales. Oceans also play a crucial role in regulating the Earth's climate, absorbing and transporting heat from the equator to the poles. Despite their importance, much of the world's oceans remain unexplored and poorly understood. Pollution, overfishing, and climate change pose major threats to ocean health and the species that call them home. As we continue to learn more about the oceans, it is essential that we take steps to protect and preserve these vital ecosystems.
