Storyboard Text

  • Hi. I am the ozone layer. I am made up of three oxygen atoms bonded in a trigonal planar resonance structure.  I help to protect you from harmful UV radiation that comes from the sun and to keep the planet warm enough for life.
  • Unfortunately, there are small holes forming in my structure. This is due to ozone depletion: known as the reduction in the concentration of ozone in the ozone layer.
  • Ozone depletion is caused by human pollutants such as CFCs and oxides of nitrogen, which disrupt the equilibrium of the atmosphere
  • When UV light shines on CFCs, it breaks the Cl-C bonds, producing a Cl radical. This molecule breaks down ozone creating more radicals.
  • Nitrogen oxides also catilitcally decompose oxygen via a radical mechanism.Essentially, oxygen radicals are formed by the breakdown of NO2 in UV light.
  • In terms of health, higher UV rays could wipe out existence on Earth, due to increases in non-melonama skin cancer cases and mutation
  • Ozone Depletion can have disastrous environmental and health related effects.
  • Environmentally, ozone depletion has links to global warming (an increase in global average temperature) that could have effects on ecosystems and sea levels.
