stepladder [879]

Halons and cfc’s both destroy ozone layer in the stratosphere.

  • They are employed as solvents, refrigerants, blowing agents for foams and packaging materials, and in the production of aerosol sprays.
  • Halons, hydrochlorofluorocarbons, and chlorofluorocarbons all damage the ozone layer, which protects the planet from damaging ultraviolet (UV-B) rays from the sun.
  • Additionally warming the earth's lower atmosphere, CFCs and HCFCs alter the climate on a global scale.
  • Life on earth is made possible by the stratospheric ozone layer, which protects the planet from the sun's harmful ultraviolet (UV-B) rays.
  • Ozone in the upper atmosphere is destroyed by man-made substances such halons, hydrofluorocarbons, and chlorofluorocarbons (CFCs)
