How is the ocean like a highway?

The ocean is like a highway in that it serves as a vast network facilitating the movement of goods and people, much like roads and highways do on land. Just as highways connect cities and regions, ocean currents connect different parts of the world, enabling trade and travel across continents. Additionally, both highways and oceans can experience heavy traffic, with ships navigating busy shipping lanes akin to vehicles on a road. Finally, both require rules and navigation systems to ensure safety and efficiency in movement.
