    White phosphorus and few other will burn without oxygen, because they will get it from water and other things.

    We would have a mass extinction if the drop in O^2 is significant enough, basically all that would be left are people who are descendants of long-term mountain inhabitants, the few that survive will probably repopulate the earth over a extremely long term.

    Well, we have a number of factors to consider here:

    -How much would the oxygen increase or decrease? If it is a small amount, it likely won't affect us. As a matter of fact, the global oxygen levels constantly change. During the months of winter in the northern hemisphere, the oxygen levels drop worldwide, because of decaying leaves (the vast majority of land is in the Northern Hemisphere).

    -If it increased by a lot, we could survive. It will likely never happen within a standard human timescale, at least enough for us to notice. Around 200 million years ago, the total atmospheric oxygen levels were around 30%, now they are around 20%. If it was 100%, we might die from oxygen poisoning. Remember, oxygen is a corrosive element, and reacts with the insides of hums. Too much is not good.

    -If it dropped, we would be much worse off. Let's say it dropped to 18%. This could widely affect out global climate, as well as numerous ecosystems, and much more. If it dropped more, we would begin to feel the effects of hypoxia, and the more severe anoxia.

    The truth is that oxygen levels will always change, and that we likely will have to worry more about carbon dioxide levels in the near future than oxygen levels.

    Sincerely,
    Geometric
