The destruction of the ozone layer Villagers remove material from the compressor of the refrigerator and air conditioner refrigerant or refrigerant compressors operate by burning and then pour coolant down. Causing coolant in older machines, particularly CFCs are substances that destroy the ozone layer, which evaporates into the atmosphere and to destroy the ozone layer that protects against radiant heat radiated into the ground too much, resulting in holes in the ozone layer.
