How do the United States and Canada use their natural resources? What are the effects of the use of these resources?

That is a big, vague question. What natural resources: iron ore, forests, oil and gas, or what? Both countries harvest, mine, drill for, natural resources as needed for commerce. There are restrictions, sometimes, on where and how that can be done. Those restrictions may vary between Canada and the United States.

i forgot to say oil
Well, okay. That does make a difference. Look up "North American oil extraction" on Google or whatever search engine you use and you'll find lots.
