Final answer:
One disadvantage of cargo ships becoming larger and able to carry more containers is that some ships are too large to fit into U.S. ports, which can pose challenges for U.S. companies' imports.
Step-by-step explanation:
One disadvantage of cargo ships becoming larger and able to carry more containers is that some ships are too large to fit into U.S. ports. This can pose challenges for U.S. companies' imports because it limits the accessibility of goods being transported. If a ship is too large to fit into a port, it may require additional costs and logistical efforts to transfer the containers to smaller vessels or transport them to the port through alternative means.
For example, if a cargo ship carrying containers from China is too large to enter a U.S. port, the containers might need to be unloaded onto smaller barges or transferred to trucks at a neighboring port. This additional step increases transportation time and adds to the overall cost of importing goods.
