- "The Columbian Exchange influenced technological advances in the late 15th and early 16th centuries. Europe was an economic and technological power compared to the Native Americans they encountered in the New World."
- "New Farming equipment like the plow seen to the left ignited the New World economy and improved health on a long term basis. The plow was highly important because it cultivated large areas of land creating a surplus of plants for both Natives and Europeans."
- "Guns and knives facilitated hunting and fishing for the Native Americans. While Natives already had knives, what they used were very malleable because they were made of obsidian and could not be used over and over like the European knives made of steel and iron. Before guns, spears, hatchets and bows and arrows were the most common used weapons of the Native Americans. A bow and arrow allowed for hunting from greater distances, but they did not do the same amount of damage as a gun. Some animals required more than one arrow to be killed."
- " European Architectural ingenuity helped to build new homes, ranches, farms, ports and ships in the new world. The establishment of these architectural structures lead to the establishment of the first colonial and native towns and also the first government buildings in the new world. Towns relocated Indians from their land into villages and towns. They also changed building patterns that used wood and charcoals which in turn led to more deforestation. Tools used for construction were made of steel and iron, this allowed natives to build stronger homes and it allowed for Europeans immigrants to build there homes to the same standard as back in Europe."
