The physiological challenge of breathing 95% carbon dioxide
In short: While Mars remains a primary target for human colonization, its atmosphere presents a lethal chemical barrier. This video explores the biological implications of a planet where nearly all the air is composed of carbon dioxide.
The core question revolves around whether humans could survive in an environment dominated by 95% carbon dioxide. Because Mars lacks breathable oxygen and possesses such a high concentration of CO2, any settlement would require significant life-support intervention to prevent asphyxiation and toxicity.
