Just doesnt support life? sounds toxic to me!

According to the Australian Maritime Safety Authority, "Prolonged exposure to moderate concentrations can cause acidosis and adverse effects on calcium phosphorus metabolism resulting in increased calcium deposits in soft tissue. Carbon dioxide is toxic to the heart and causes diminished contractile force. At concentrations of three per cent by volume in air, it is mildly narcotic and causes increased blood pressure and pulse rate, and causes reduced hearing. At concentrations of about five per cent by volume it causes stimulation of the respiratory centre, dizziness, confusion and difficulty in breathing accompanied by headache and shortness of breath. At about eight per cent concentration it causes headache, sweating, dim vision, tremor and loss of consciousness after exposure for between five and ten minutes."

Also Co2 is used in gas chambers as well. its a toxic gas. Once again im just splitting hairs cause im bored.

This reminds me of the trapped coal miners- they were never found. They finally have to implode the mine and made a big tomb. So sad, I can’t imagine dying slowly from poisonous CO2 gases. Just the thought of suffocation scares the heck out of me.
