Eating meat-less one day a week is an easy way to help ozone depletion.
B
Correct answer
Explanation
Ozone depletion is primarily caused by chlorofluorocarbons (CFCs) and other ozone-depleting substances used in refrigeration and aerosols, not by meat consumption or livestock raising. Livestock and meat production are more commonly discussed in the context of greenhouse gas emissions and climate change rather than stratospheric ozone depletion.
