Think of these notes like a conversation with a friend who's an environmental genius. Ready? Here we go!

Halocarbons, which includes the notorious chlorofluorocarbons (CFCs), are the primary culprits behind ozone depletion. Where do you find them? In many everyday products! Picture this: You're using a can of hairspray (aerosol), or chilling near your fridge, or relaxing in a room cooled by an air conditioner - you're hanging out with CFCs! They're also in things like foamed plastics, some pesticides, fire extinguishers, and solvents.

Fun Fact: CFCs are like that super stable friend who rarely loses their cool, but when they do (in this case when exposed to ultraviolet radiation in the stratosphere), they release halogen atoms that are not so friendly to our ozone layer.

When these halogen atoms get excited by UV radiation, they start reacting with oxygen in the stratosphere and mess up the rate of ozone re-formation. They're like a group of party crashers that make it hard for the ozone party to get back into full swing.
