Is there enough oxygen on Mars for humans to breathe?

Currently, Mars has an extremely thin atmosphere with only about 0.1% the density of Earth's atmosphere. This means that there is not enough oxygen on Mars for humans to breathe. The majority of Mars' atmosphere is composed of carbon dioxide, making the air highly toxic and unbreathable for humans. If humans were to live on Mars, it would be necessary to either bring or generate oxygen for them to survive. Various methods have been proposed, such as extracting oxygen from the Martian soil or through electrolysis of water molecules already present on the planet. These approaches are being researched and developed to enable future human colonization of Mars.
