  • POLUTION
    • Carbon Dioxide
      • Extra carbon dioxide in the atmosphere increases the greenhouse effect.
      • Carbon dioxide is essential to the survival of plants and animals. Not only do plants and animals need to ingest carbon dioxide, but they also rely on the gas to keep them warm, as it is an essential component to Earth's atmosphere.
      • Rising CO2 levels in the atmosphere enhance crop yields.
      • Carbon dioxide is produced by burning fossil fuels, such as like coal, oil, petrol and natural gas
    • Sulphur Dioxide
      • When sulfur dioxide combines with water and air, it forms sulfuric acid, which is the main component of acid rain which can cause deforestation.
      • Sulphur dioxide has been linked to cardiovascular disease.
      • Sulphur dioxide can cause respiratory problems such as bronchitis, and can irritate your nose, throat and lungs.
      • The main source of sulfur dioxide in the air is industrial activity that processes materials that contain sulfur, eg the generation of electricity from coal, oil or gas that contains sulfur
    • Nitrogen Oxides
      • Nitrogen oxide damages the ozone layer, thus reducing the protection offered from harmful UV sun rays
      • NOx is produced from the reaction of nitrogen and oxygen gases in the air during combustion
        • High levels of NOx can have a negative effect on vegetation
        • NOx gases react to form smog and acid rain as well as being central to the formation of fine particles (PM) and ground level ozone, both of which are associated with adverse health effects.
      • In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution
    • Solid particulates
      • makes lakes and streams acidic
      • changing the nutrient balance in coastal waters and large river basins
      • depleting the nutrients in soil
      • damaging sensitive forests and farm crops
      • damaging sensitive forests and farm crops
      • contributing to acid rain effects.
      • ncludes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. ... directly emitted, for instance when fuel is burnt and when dust is carried by wind, or. indirectly formed, when gaseouspollutants previously emitted to air turn into particulate matter.
