The Montreal Protocol, finalized in 1987, represents a watershed moment in environmental governance, successfully phasing out 99% of ozone-depleting substances and showing effective global cooperation.

Although we’re witnessing some recovery of the ozone layer, contradictions remain as new holes still appear, highlighting ongoing challenges in fully addressing atmospheric health.
The ozone layer acts as Earth’s sunscreen, essential for protecting living organisms from harmful UV radiation that causes serious health and ecological issues.
