What is the island occupied by Columbus? What effect did his arrival have on the residents?

America! The opening of the new air route ended the relative isolation of all parts of the world, the civilizations of all parts began to meet and blend, and the prototype of the world market centered on Western Europe began to appear, which proved the theory of geoparks. Negative effects: people in Asia, Africa and Latin America suffered great disasters, with huge property losses, and Africa and America became colonies and semi-colonies day by day.

After Columbus discovered America, a large number of European immigrants poured in, occupying the living space of Native Americans (Indians). 2. European colonists, first Spain and Portugal, then Britain and France, occupied Indian land, plundered natural resources and destroyed Indian civilization. 3. European immigrants brought smallpox, measles and other infectious diseases from Europe, and Indians who lived in America for a long time were not immune to these diseases, while Spanish and British colonists attacked them.
