Atmosphere: Air
  1. COMPOSITION
    1. Nitrogen 78%
      1. Oxygen 21%
        1. Noble Gases <1%
          1. Carbon Dioxide 0.03%
            1. Carbon Cycle
              1. Production of carbon dioxide
                1. Respiration
                2. Removal of carbon dioxide
                  1. Photosynthesis
            2. ATMOSPHERIC POLLUTANTS
              1. Carbon Monoxide
                1. PRODUCED BY incomplete combustion of carbon-containing substances
                  1. CAUSES death. Very poisonous, that's why some people die in their cars.
                    1. REDUCED BY catalytic converters. (convert CO to CO2)
                    2. Sulfur Dioxide
                      1. PRODUCED BY volcanic eruptions & combustion of fossil fuels.
                        1. CAUSES acid rain & breathing difficulties.
                          1. REDUCED BY flue gas desulfurisation. (CaCO3 removes SO2)
                          2. Oxides of nitrogen (NO and NO2)
                            1. PRODUCED BY lightning activity & internal combustion engines.
                              1. CAUSES acid rain & lung damage.
                                1. REDUCED BY catalytic converters. (Convert NO and NO2 to N2 nitrogen)
                                2. Methane
                                  1. PRODUCED BY bacterial decay of organic matter & human activities
                                    1. CAUSES greenhouse effect & global warming (it's a greenhouse gas)
                                    2. Unburnt Hydrocarbons
                                      1. PRODUCED BY incomplete combustion of carbon-containing fuels.
                                        1. CAUSES photochemical smog (don't we love this word) & formation of ozone.
                                          1. REDUCED BY catalytic converters.
                                          2. Ozone
                                            1. PRODUCED BY photochemical reactions
                                              1. CAUSES eye irritation & respiratory problems.
                                                1. REDUCED BY reducing emissions of unburnt hydrocarbon fuels.
