In fact, according to Wikipedia, carbon dioxide constitutes less than 0.4% of the Earth's atmosphere, and
Toxicity and its effects increase with the concentration of CO2, here given in volume percent of CO2 in the air:

Toxicity and its effects increase with the concentration of CO2, here given in volume percent of CO2 in the air:
- 1%, as can occur in a crowded auditorium with poor ventilation, can cause drowsiness with prolonged exposure.
- At 2% it is mildly narcotic and causes increased blood pressure and pulse rate, and causes reduced hearing.
- At about 5% it causes stimulation of the respiratory centre, dizziness, confusion and difficulty in breathing accompanied by headache and shortness of breath.
- At about 8% it causes headache, sweating, dim vision, tremor and loss of consciousness after exposure for between five and ten minutes.
