Just wait until someone accidentally burns the shit out of themselves. It actually happens all the time with medical oxygen in hospitals, as in, a controlled environment where oxygen use is expected, and the injuries can be severe, even deadly. Imagine bringing one of these to a BBQ, someone lights the grill too close to you, fwoomp

    Or, maybe if you’re a dinosaur and you evolved under something like 60% air oxygen, which was actually why animals were so big back then.

    I agree with the most part, but I’m pretty sure that the greater size of the animals was due to high levels of oxygen, not low ones. Because the bigger you get, the more difficult does it become to capture enough oxygen and distribute it through your large body for the big demand of oxygen that your massive amount of cells have.

    Edit: I’m wrong. Sorry for terrible link, but was the first thing I found on the issue: https://www.firstpost.com/tech/news-analysis/atmospheric-oxygen-during-dinosaurs-time-much-lower-than-assumed-says-study-2-3641691.html

    The results of this comprehensive study suggest that atmospheric oxygen during most of the past 220 million years was considerably lower than today’s 21 per cent.

    “We suggest numbers between 10 and 15 per cent,” said Tappert.

    Tappert now suggests to reconsider these theories: “We do not want to negate the influence of oxygen for the evolution of life in general with our study, but the gigantism of dinosaurs cannot be explained by those theories.”
