Can you breathe on Mars?

Not without the aid of a breathing apparatus. Mar's atmosphere is nearly 96 % carbon dioxide.Humans cannot breathe on Mars. The atmosphere is thin and made almost entirely of carbon dioxide, a poisonous gas.Without being encapsulated with an oxygen supply? If you did it wouldn't be long before you were not breathing at all.The atmosphere is mostly carbon dioxide (what we breathe out), and very tiny amounts of oxygen (what we breathe in). So air there does not have what we need, to breathe it successfully, but that's not the entire problem. Mars is also very cold. In fact you'd freeze to death before realizing that you were suffocating.No you could not breath the air on Mars, first the atmosphere is very thin (it is at a very low pressure 0.6 kPa, compared to Earth's 101.3 kPa) and second the atmosphere contains no oxygen.The atmosphere on Mars consists of 95% carbon dioxide, 3% nitrogen, 1.6% argon. The atmosphere is also quite dusty, giving the Martian sky a tawny color when seen from the surface.
