In this video, viewers learn how the development of land- and sea-based transportation changed the world. Transportation by land created a more rapid exchange of goods, information, and travel as well as the development of commerce. As transportation systems advanced from good roads to railroads followed soon after by the automobile, they changed the speed of commerce, travel, communication, and also the way society functioned. Sea-based transportation opened up the entire world, allowing long-distance travel and trade with faraway places. Today, marine transportation is the most economical and efficient form of transporting large quantities of goods, and containerized shipping has revolutionized how countries trade. The video also discusses environmental concerns including scarce resources and escalating pollution. (18 min.) A Meridian Production.
