Final answer:
Government trade restrictions generally act as barriers to trade, differing from globalization, containerization, and efficient port infrastructure, which enhance maritime freight traffic.
Step-by-step explanation:
The main answer to the question regarding what has fueled the systematic growth of maritime freight traffic, except one, can be determined from understanding the factors that have contributed to globalization. Among the factors such as globalization, containerization, and efficient port infrastructure that have promoted the growth of maritime freight traffic, government trade restrictions typically serve as a deterrent to such growth rather than a contributing factor. Examining the historical and current trends, it is evident that trade restrictions like tariffs and import quotas are intended to limit trade rather than facilitate it, which is in contrast to the other options listed. Globalization is characterized by the reduction of trade barriers and improvements in transportation and communication, leading to a decrease in costs and ease of long-distance economic activities. Containerization has revolutionized freight transport by significantly lowering shipping costs. Efficient port infrastructures have allowed for quicker loading and unloading, and better handling of cargo, which in turn accelerates the trade flow. On the contrary, trade restrictions like tariffs and quotas generally act as barriers that reduce the volume of trade by making it more expensive or difficult.
