EXTRACTION AND USE OF NATURAL RESOURCES
Canadians have concerns about extraction of natural resources from the Canadian Shield. Some natural resources are renewable, such as timber from the forest and fish from the Hudson Bay. However, in the Canadian Shield, there are many sources of minerals and oil. These resources are nonrenewable and cause damage to the land when they are extracted. There are concerns about permanent damage to the land and wildlife populations. This issue continues to be debated among Canadian people.
