No,humans would not have enough oxygen to live with.People in other continents would die.Maybe one person could survive with one tree, but the whole world,it's impossible.
No. Earth's oxygen is provided by plants. Humans need oxygen to live, so we could not have been there before there was oxygen, so we could not have made the oxygen.
oxygen
to live and
it is AEROBES
Oxygen is important to the society because without it, we could not live. we need Oxygen for us humans to live, for the animals and environment. that is the most important point as to why we need Oxygen. we also use Oxygen for hospitals, burning things like paper, and more. Oxygen is something we have to live with as it is what we survive on.
An aquarium usually has water in it, and humans cannot live under water, so no. Definitely not without a adequate air supply such as SCUBA. Even if you did have an oxygen source, it wouldn't allow you to "live" in the aquarium.

In order to live.
oxygen
anywhere where there isn't oxygen (air)
In a sense. But it is not the chemistry of those planets but human biochemistry. Humans need a continuous supply of oxygen to keep their metabolisms running. A human deprived of oxygen for more than a few minutes will die.
Possible. We could grow plant and have animals. But there is oxygen so it is almost impossible.
