Question

what are the steps taken to Limit ozone depletion

Answer 1

Replace it with a model without this harmful ozone-depleting chemical. Don't buy aerosol products with chlorofluorocarbons (CFC). Although CFCs have been banned or reduced in many applications, the only way to be sure is to check the label on all your hairsprays, deodorants and household chemicals.

Answer 2

The Montreal Protocol, banning signatory countries from making and using CFCs.

Lip service paid to attempts to reduce / counter Global Warming, which could limit the amount of water vapor pumped into the ozone layer (where it depletes ozone).
