Ozone loss was a thing even before CFCs were widely used
New scientific findings suggest ozone layer depletion began decades before the discovery of the ozone hole and was driven by substances other than CFCs.

The brief
Recent research indicates that ozone loss occurred prior to the widespread use of chlorofluorocarbons (CFCs). This suggests the damage to the ozone layer started much earlier than previously understood.
Coverage from Phys.org, Ars Technica, Gizmodo, and heise online emphasizes that the earliest causes of the ozone hole were not CFCs. The reports highlight a shift in the scientific understanding of the timeline regarding ozone depletion.
Future developments depend on the identification of the specific substances responsible for the early damage, as coverage indicates the depletion was caused by other substances.
