$\text{CFCs} $
✓
Answer
$\text{CFCs} :\ ($Chlorofluorocarbons$)$ are organic compounds that contain carbon, chlorine, fluorine produced as volatile derivatives of methane and ethane which catalyze the conversion of ozone $(O_3)$ into $O_2,$ while $O_3$ is more powerful to absorb ultra$-$violet rays than that of $O_2.$ So $\text{CFCs}$ disturb the ozone layer which is so essential for the earth.
