Chloroflourocarbons are not directly hazardous to humans, the chlorine in them rises to the ozone and turns the ozone into normal oxygen, which does not protect us from cosmic radiation, hence the hole in the ozone layer.

How do CFCs affect animals?
They don't. CFCs (chlorofluorocarbons) are non-toxic to humans and animals. They only kill ozone molecules.
Are all CFCs greenhouse gasses?
Yes, even though they are primarily harmful because of their effect on ozone depletion. CFCs have both effects. The two effects are different. The ozone depletion is worse.
Humans have greatly increased the level of what in the atmosphere?
carbon dioxide
How do humans destroy the ozone?
The humans destroy ozone by usng CFCs. These are compounds which react with ozone to deplete it.
Did humans ban cfcs to help protect the ozone?
Yes they did. CFC's were causing depletion to ozone.
How do human activities contribute CFC's to the atmosphere?
humans use products containing CFCs which accumulate in the atmosphere.
Why are humans causeing the hole in the ozone layer?
Humans are causing the hole in ozone layer by using CFCs. These CFC are the factors responsible for depletion of ozone.
Are humans responsible for the depletion of the ozone layer?
Yes. People developed chemicals such as CFCs (Chlorofluorocarbons) for use in refrigerators and as a propellant gas in aerosols. These CFCs rose high into the atmosphere and caused damage to the ozone layer. the use of CFCs has since been banned and the ozone layer is slowly recovering. Hopefully.
Can rain demolish CFCs?
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
Why was a ban on CFCs necessary?
Ban on CFC's is a necessity. The ban is necessary because of the harmful effects.
How are humans contributing to the thinning of the ozone layer?
By using CFCs such as aerosols, old fridges, air-conditioning units and polystyrene foam
Why is it important to phase out the use of chlorofluorocarbons?
Countries agreed at the Montreal Conference to ban the use of chlorofluorocarbons (CFCs). It was clear to everyone that CFCs were damaging the ozone layer and this could lead to severe damage to humans. This ban has been the most successful international intervention ever. No CFCs are now being released and scientists hope the ozone level will have self-repaired by 2060 (CFCs hang about in the atmosphere for up to 75 years!).
