Answer:
It would become highly difficult to extinguish fires because oxygen supports combustion. This could of course leave heavy destruction around us. Despite what many people believe, humans can easily breathe 70% oxygen without a problem. We do this all the time in hospitals. So there would be plenty more oxygen for animals. However another downside is that it would be more difficult for plants to make their own food.
