Ozone Layer's Vital Protection
- The ozone layer acts as Earth's protective shield by absorbing harmful ultraviolet radiation from the sun.
- Its healing is vital for protecting life and is progressing globally due to international cooperation.
Healing Timeline and Cause
- The ozone layer is expected to heal to pre-1980 levels by 2040 globally, with polar regions recovering slightly later.
- This recovery stems from the 1987 Montreal Protocol reducing harmful CFC emissions worldwide.
CFCs: Dual Environmental Threat
- CFCs were used mainly as solvents and refrigerants but also severely damage the ozone and trap heat as potent greenhouse gases.
- One molecule of CFC-12 can hold nearly 11,000 times the heat of carbon dioxide.
