Lower levels of ozone allowed more ultraviolet radiation to reach Earth.

CFCs release chlorine atoms in the stratosphere that catalytically destroy ozone, thinning the ozone layer (e.g., the Antarctic ozone hole). That increases UV‑B reaching the surface, raising risks of skin cancer, cataracts, and ecological harm.
