Transportation and communication are called lifelines because they are the essential arteries that connect producers, suppliers, and consumers, forming the backbone of the economy. A dense and efficient transport network facilitates the movement of raw materials to industries and finished goods to markets, both domestic and international. This accelerates development and trade. Similarly, modern communication systems like the internet and telecommunication allow for the instant exchange of information, enabling global business operations, e-commerce, and the management of complex supply chains. Without these lifelines, the pace of development would slow dramatically, isolating regions and hindering economic growth and national integration.
