If we’ve stopped producing CFCs, then why do we still need to worry about the ozone hole?
Created: Tuesday, July 20, 2004
It will take many years for the ozone hole to heal. Since the phaseout of ozone-depleting compounds (like CFCs), the atmospheric concentrations of many of these gases are either increasing more slowly or decreasing. However, ozone levels are likely to be lower than pre-depletion levels for several decades.
