What influence did Columbus and three other navigators have on the world?

/kloc-in the 0/5th century, the east and west at both ends of the Eurasian continent marched into the sea almost simultaneously. The East is represented by China Zheng He's voyage to the West, and the West is represented by Columbus's voyage to the West. Navigation between the east and the west, in a great sense, marks the beginning of the stage of human activities from the mainland to the ocean.

Great voyage is the practice of human understanding the value and function of the ocean. However, there is a difference between the social foundation that gave birth to and created oriental navigation and western navigation activities.

The driving force of West Airlines is economic factors, and the development of European commodity economy and the urgent requirement of emerging capitalism to accumulate capital are the main driving forces of West Airlines. Columbus discovered two big islands, Cuba and Haiti, and several small islands in the Indian Islands in the eastern and central America, thus opening the curtain of discovering the new continent. Columbus and his party opened up a new route from Europe across the Atlantic to America and back safely, thus closely linking America and Europe, and then the New World and the Old World. Western navigation promoted the development of world history, but their navigation was bloody.

Zheng He's voyages to the West were mainly due to political considerations and economic activities. The main tasks are to wipe out maritime bandits, adjust and ease conflicts with other countries, calm conflicts, and maintain stability and maritime security in Southeast Asia and South Asia; Another important content is official trade, which takes the form of bargaining, which embodies the principle and spirit of equality, voluntariness and fairness; There are also cultural exchanges and civilized dialogues with relevant countries.
