The causes of Ozone Depletion is mainly pollution. CFCs play a great part on Ozone Depletion too. Air conditioners, Refrigerators are one of the examples of machines that give off CFCs. The consequences of Ozone Depletion is that it will cause Global Warming because Ozone Layer keeps UV Rays or Ultraviolet rays from coming in contact with earth. With it depleting, UV Rays are more likely to enter earth and cause Global Warming. Hope that helped.
CFCs are Chlorofluorocarbon by the way.
