Final answer:
Wilderness refers to a natural area largely untouched by human activities, often with diverse flora and fauna. The Canadian Shield is known for such wilderness, offering a glimpse of nature without extensive human impact.
Step-by-step explanation:
The term wilderness refers to a natural environment that is largely untouched by human activities and is in a relatively undisturbed state. It is characterized by a diversity of plants and animals, as well as landforms that have not been significantly altered by human development or agriculture. When we talk about the Canadian Shield region being known for its wilderness, we are indicating that it is a large area with vast tracts of forests, rock, and bodies of water that have not been heavily impacted by urbanization or industrialization. This makes the Canadian Shield a place where one can experience the natural world as it exists without extensive human intervention.
