The ozone hole is mostly repaired, because we stopped using CFC's.

    I think it's more accurate to say the problem is mostly solved and its on track to being repaired rather than mostly repaired.

    Antarctic ozone hole:
    2000: 28.3 million sq km (largest recorded).
    2020: 24 million sq km.
    2024: 20 million sq km (approx 3x size of usa).

    Global ozone levels will return to 1980 levels around 2040.
    Arctic ozone will recover by 2045 (currently around 1 million sq km).
    Antarctic ozone hole will fully recover by 2066.
