What does the graph predict will happen to chlorine concentrations if cfcs are phased out?

The graph likely predicts that if chlorofluorocarbons (CFCs) are phased out, chlorine concentrations in the atmosphere will gradually decrease over time. This is because CFCs are a significant source of chlorine, which contributes to ozone depletion. As the atmospheric levels of CFCs decline, the release of chlorine into the stratosphere will reduce, leading to a recovery of ozone levels. Ultimately, the graph suggests a positive impact on the ozone layer as chlorine concentrations diminish.
