Answer:
Canada and the US, prior to the contact between Europeans and Native Americans, were home to numerous civilizations, a huge number of settlements, an agricultural landscape, and a lot of different cultures.
Explanation:
Present-day Canada and the United States, prior to the contact between the Europeans and Native Americans were very different places. The Native Americans were in very large numbers, though much more in the US and less in Canada. There were a lot of thriving civilizations across the continent, and the different groups of people had different lifestyles.
Across North America, there were thousands of settlements, some of which were cities or villages, while some were temporary dwellings. Unlike the common belief, the Native Americans, at least the ones that had a settled lifestyle, were on a relatively similar level of development as the Europeans, and they exploited the continent a lot. The landscape was changing from one place to another because of the type of human activity that was dominant, and what is now the US especially, was much less forested because of agricultural activities than what the Europeans saw after they started to move westward sometime after their initial arrival.
