Final answer:
North America was the primary region where Europeans settled to exploit its vast natural resources and establish trade routes during the settler colonies era.
Step-by-step explanation:
During the era of settler colonies, North America was the primary region settled by Europeans for the purpose of exploiting its vast natural resources and establishing lucrative trade routes. European settlers sought to capitalize on the economically valuable natural resources such as furs, metals, wood, and agricultural products like tobacco and cotton. The settlements also facilitated the colonial powers' goal of expanding their empire and establishing dominance over trade and other economic activities.
Imperialism in Africa and other regions, like the Middle East and Asia, was also driven by the search for natural resources and the establishment of trade dominance. In particular, the scramble for colonies in Africa resulted in the extraction of resources such as copper, rubber, and ivory, with European powers establishing plantations and mining industries. However, the initial settler colonization efforts with large-scale agriculture and resource exploitation were most prominent in North America.
