you cant get too much. once the air has reached 100% oxygen no more can get in the air. if you breathe it in, you might feel a bit dizzy as you're not used to it but its not harmful at all, just not used to it
Yes, it is possible to have too much oxygen in your body, known as hyperoxia. This can lead to oxygen toxicity, causing symptoms such as confusion, dizziness, breathing difficulties, and in severe cases, lung damage. It is important to follow medical guidance when using supplemental oxygen to prevent this.
Too much air would harm the body
if ther will be too much nitrogen so oxygen will decrease and we will be breathless .
this happen you a person is tired orhas a luck of oxygen in there body
Anything that burns in the natural atmosphere, which is only about one fifth oxygen, would burn much faster in pure oxygen.
You have established in the question that too much oxygen has been lost, so this means that there will be some degree of impairment due to brain damage. How much impairment will depend on how little oxygen the brain received, over how long a period, and on the temperature of the brain.
Some of the oxygen will dissolve in the water.
If Earth had twice as much oxygen as it does, fires would start easier and burn hotter. Arthropods (insects, spiders and the like) could be a good deal larger than they are now.
there would be no oxygen
It contracts?
You will die
Nowhere, animals do not produce oxygen.
More oxygen means less CO2 so we could experience global cooling. Oxygen also feeds combustion so there could be bigger and more frequent forest fires.
