My interest was piqued when you mentioned cuts would heal faster. Is there a video that explains what life would be like if the earth had higher concentrations

  On mobile, will let someone else search. But what springs to mind : more O2 means faster reactions, so faster metabolisms, so bigger animals and more cancer. Though the latter only compared to equally sized animals today (bigger animals tend to have lower cancer rates I think?)
