the earth would die
Some Bacteria do not need and will even die in the presence of oxygen. They would thrive and probably evolve.
most plants and animals would die due to the lack of food and oxygen
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.
We would all die. As there won't be enough oxygen for us to breathe in.
The oxygen isn't "used by the earth"; it is recycled by organisms. The total amount of oxygen on planet Earth remains more or less constant.
You will die
we would be dead
If the sun exploded it would not give us oxygen; it would simply vaporize Earth.
no air and no oxygen
all human and animal activity would die
Some Bacteria do not need and will even die in the presence of oxygen. They would thrive and probably evolve.
we well not get oxygen and all earth get die
Humans would die, because plants make our oxygen
we will die because there is no oxygen to breathe in
The thick atmosphere has enough oxygen so than living things can happen.
if there is no plants humans cant get oxygen so naturally people cant exist on earth
most plants and animals would die due to the lack of food and oxygen
