Oceans as the highway of trade
Age 18 · Geography
Most of the goods we use travel by sea, packed into standard containers on huge ships that follow set routes and squeeze through narrow straits. Coastal countries control the resources in a sea zone reaching 200 nautical miles from their shore, while ships from every nation may still sail through it.
