The most expensive and difficult part of space travel is getting into orbit around the Earth. Once you are in Earth orbit, you are over half-way there - no matter where "there" is!
The suggestion of taking some of Earth's oxygen and transporting it to Mars has a number of difficulties. The cost of the oxygen would be negligible compared to the cost of rocket fuel to get it into orbit, and the cost of the rocket fuel to get the oxygen - and the containers to carry so much of it - would doom the project. Fortunately, there is plenty of oxygen on Mars already.
The red dirt of Mars seems to be substantially "rust"; iron oxide. Martian colonists will probably build solar power plants on Mars to generate electricity, and use the electricity to process the iron oxide in Mars' red dirt into iron that can be used for machines and colony buildings, and oxygen to give the colonists the air they will breathe.
There is even more oxygen that's already in space, even though it is a little further away. Astronomers believe that a substantial part of the rings of Saturn may be in the form of water ice. If so, it would be possible to bring the ice from Saturn's rings to Mars more cheaply than trying to lift water from the surface of the Earth to orbit.
The atmosphere is 79.9% oxygen.
The moon has no oxygen because it has no atmosphere.
Plants gives us most of our oxygen in the atmosphere.
Yes, trees do provide most of our oxygen for the atmosphere
when a balloon floats up into the atmosphere it pops because a balloon need oxygen and there is no oxygen in the atmosphere
Oxygen, produces it.

don't smoke, excercise, espessially walking.
mercury's atmosphere is thin so sound waves don't travel very well and there is little oxygen.
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
True
green vegetation are plants and of course plants give out oxygen and take our carbondioxide
Oxygen is already 20.946% by volume, So an increase of 0.054% should not make any difference
Greate Oxygenation Event, This dramatically caused a new ice age because of the increase effecting the atmosphere.
Oxygen. Earth's early(first) atmosphere is believed to contain hydrogen cyanide, carbon dioxide, carbon monoxide, nitrogen, hydrogen sulfide, and water. but still it only had little to no oxygen.
The oxygen in the atmosphere is the O-Zone which is O3 (Oxygen 3) because of plant life oxygen had increased via photosynthesis, the incease just allowed the ozone to thicken, but sadly due to CFC there are large holes
