Chlorofluorocarbons (CFCs) damage the ozone layer. Where do these chemicals come from?
Caleb Allenthey are mostly coming fro m leakages in refrigerators and aerosols/
These days' refrigerators use safe refrigerants that degrade at the stratosphere and harm the ozone layer.

Nathan AbbeChlorofluorocarbons (CFCs) primarily come from human activities, such as industrial processes and the use of certain products. These chemicals were commonly used in aerosol propellants, refrigerants, solvents, and foam-blowing agents before their harmful effects on the ozone layer were recognized.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
