Hm… humans (all mammals, really) react with great distress to high CO2 concentrations in the air. Now, the concentrations at which that reaction can be measured are MUCH higher than the current ones. But it does make me wonder whether we are reacting to them subconsciously anyway. That might help explain the increased incidence of anxiety and depression, among many other things. |
