The correct answer to this question is the following.
Although there are no options attached, we can say the following.
As Columbus and others set off looking for wealth, glory, and converts to God, the impact of European conquest on the population and environment of the New World was disastrous. European explorers and colonists really damaged and affected the environment in the Americas and almost wiped out 80% of the Native Indian population due to diseases.
The sole interest of white European conquerors and colonists was to exploit the many raw materials and natural resources of the Americas to make a profit. That was the case of the Spaniards in Mesoamerica. The English settlers in North America wanted to settle in the territories that belonged to the Native American Indian tribes. This created many conflicts and wars. In the end, Indians were removed from their territories.
And regarding diseases, white Europeans brought diseases such as cholera, influenza, chickenpox, malaria, and smallpox, that almost wipe out the entire Indian population in the Americas.
