I was wondering what are some natural resources needed for survival and the consequences for not having those resources. I would like some research cites or cite your resources(where you got the info)

We must have air, water, food, and shelter.

I need to list 5 resources (natural resources) and list the consequences for each of them if we didn't have them.
Air, water, food, and shelter are all composed of natural resources. Fire could be the fifth natural resource.
Ok that is what I all have. What would be the consquences for not having air (oxygen-would be better) besides that plants would not be able to grow. What else would happen if there was no oxygen in the environment?
What would be some consequences if any of these resources would become limited. I need 1 for each of these: individual, community and population. I need to list the consequences for each of these 3 categories for each of the resources that I chose-the ones above that I mentioned earlier. (Oxygen, food, water, shelter and fire)
