The main negative effects were the propagation of slavery and the spread of communicable diseases. European settlers brought tons of communicable diseases to the Americans. Indigenous peoples had not built up immunity, and many deaths resulted. Smallpox and measles were brought to the Americas with animals and peoples.

The main effect of the Columbian Exchange was diseases that were carried by the explorers killed 90% of Native Americans. After the Native Americans died off who did the the explorers use to grow their crops? Due to the death of so many Native Americans, the demand for African American slaves increased.

Invasive species, including communicable diseases, were a byproduct of the exchange. The changes in agriculture significantly altered global populations. The most significant immediate effects of the Columbian exchange were the cultural exchanges and the transfer of people (both free and enslaved) between continents.

The Columbian Exchange caused population growth in Europe by bringing new crops from the Americas and started Europe’s economic shift towards capitalism. Colonization disrupted ecosytems, bringing in new organisms like pigs, while completely eliminating others like beavers.

Causes and Consequences of Exploration, Immigration, Settlement Patterns, and Growth. The Columbian Exchange—Columbus’s discovery of the New World was the first link in the great chain of cause and effect known as the Columbian Exchange.

What caused the Columbian Exchange? Explorers spread and collected new plants, animals, and ideas around the globe as they traveled. An economic system based on private ownership and on the investment of money in business ventures in order to make a profit. This leads to inflation(having more money than goods).

The exchange of plants, animals, diseases, and technologies between the Americas and the rest of the world following Columbus’s voyages. cultivation by the Portuguese in Brazil needed lots of labor, increased enslavement. Sugar plantations were called engenhos.

The Columbian exchange of crops affected both the Old World and the New. More importantly, they were stripping and burning forests, exposing the native minor flora to direct sunlight and to the hooves and teeth of Old World livestock. The native flora could not tolerate the stress.

Food products, livestock, and diseases are but three elements of the Columbian Exchange. As Columbus “discovered America” and Western Europe discovered the various economic opportunities available in the New World, agriculturalexchanges between the two regions led to exchanges of other items.
