Summary

The ozone layer is healing after being depleted by CFCs, thanks to the Montreal Protocol, which led to a global phase-out of harmful chemicals.

Highlights

  • 🌍 Ozone layer depletion was a major environmental crisis in the 1980s.
  • 🧪 CFCs, used in many products, were identified as the primary cause of ozone depletion.
  • ❄️ The Antarctic’s unique conditions accelerated ozone destruction.
  • 📉 The ozone hole has been shrinking since 2006 due to international agreements.
  • 🌋 Natural events like volcanoes still impact the ozone layer’s recovery.
  • 🌡️ Without global action, temperatures could have risen significantly.
  • 🌈 The ozone layer is expected to return to healthy levels this century.
