Final answer:
Chlorine and bromine gases released from aerosol sprays, coolants, and other products are major contributors to the hole in the ozone layer. These gases break down ozone molecules, leading to a depletion in ozone concentrations and the formation of the ozone hole.
Step-by-step explanation:
The major contributor to the hole in the ozone layer is the release of chlorine and bromine gases from aerosol sprays, coolants, and other products.
These gases, specifically chlorofluorocarbons (CFCs), break down ozone molecules in the upper atmosphere, leading to a depletion in ozone concentrations and the formation of the ozone hole.
This depletion is a significant environmental issue, resulting in higher levels of UV radiation reaching Earth, which can increase skin cancers, eye cataracts, and disrupt ecosystems.
