With the modern developments in transportation and communications, man has controlled time and distance. During the past 50 years, the world’s means of transport and communication have been revolutionised. These changes have been marked with more rapid movement from place to place.
The ocean transport has served as a global, unbroken link between distant lands. The development of air transport has reduced the element of time. The major countries of the world are connected by air routes. Air transport has conquered physical barriers. The inter-continental air routes over the oceans have linked different continents. These fast means of transport have brought different areas closer to each other. It appears as if the world is shrinking day by day and we are living in smaller world.
