The initial step in the depletion of stratospheric ozone by human activities is the emission of ozone‐depleting gases containing chlorine and bromine at Earth's surface. Most of these gases accumulate in the lower atmosphere because they are unreactive and do not dissolve readily in rain or snow. Eventually, the emitted gases are transported to the stratosphere where they are converted to more reactive gases containing chlorine and bromine. These more reactive gases then participate in reactions that destroy ozone. Finally, when air returns to be lower atmosphere, these reactive chlorine and bromine gases are removed from Earth's atmosphere by rain and snow.
Certain industrial processes and consumer products result in the atmospheric emission of "halogen source gases". These gases contain chlorine and bromine atoms, which are known to be harmful to the ozone layer. For example the chlorofluorocarbons (CFCs) and hydro chlorofluorocarbons (HCFCs), once used in almost all refrigeration and air conditioning systems; eventually reach the stratosphere where they are broken apart to release ozone‐depleting chlorine atoms. Other examples of human‐produced ozone‐ depleting gases are the "halons", which are used in fire extinguishers and which contain ozone -depleting bromine atoms. The production and consumption of all principal halogen source gases by human activities are regulate worldwide under the Montreal Protocol.
Cow emissions, such as methane, can contribute to ozone depletion indirectly by influencing the levels of ozone-depleting substances like chlorine in the atmosphere. However, the impact of cow emissions on ozone depletion is relatively small compared to other human activities like industrial and transportation emissions.
Actually the questions must be the other way round that is the largest percentage of human-made carbon dioxide emissions responsible for ozone depletion. But still carbon dioxide is not the only reason for the ozone depletion. Various other factors such as freons, CFC's etc are responsible for ozone depletion.
The main reasons for the depletion of the ozone layer are the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances into the atmosphere. These substances break down ozone molecules, leading to a reduction in the ozone layer's protective qualities. Additionally, certain human activities, such as industrial processes and emissions from vehicles, can contribute to ozone depletion.
In the 1970s humans released CFCs into the atmosphere. It was used as a gas in aerosol cans, refrigerators and air conditioners. Production of CFCs was phased out after the Montreal Protocol in 1989. Scientists hope the ozone layer will be repaired around 2050.
Ozone depletion in the stratosphere is an environmental problem. It is primarily caused by human activities that release substances like chlorofluorocarbons (CFCs) that destroy the ozone layer, leading to increased exposure to harmful ultraviolet radiation. This depletion can have wide-ranging impacts on ecosystems, human health, and the environment.
Ozone depletion potential refers to the potential at which the ozone is depleting. Human activities are the main reason for its depletion.
Cow emissions, such as methane, can contribute to ozone depletion indirectly by influencing the levels of ozone-depleting substances like chlorine in the atmosphere. However, the impact of cow emissions on ozone depletion is relatively small compared to other human activities like industrial and transportation emissions.
The release of CFC's lead to ozone layer depletion. It reacts with ozone to deplete it.

yeah but not really...it's mostly human activities

Volcanoes release sulfur dioxide and ash into the atmosphere, but their impact on ozone depletion is minimal compared to human activities. Oceans do not contribute to ozone depletion but play a role in absorbing harmful ultraviolet radiation.
Carbon emissions contribute to climate change by trapping heat in the atmosphere, but they do not directly destroy the ozone layer. Ozone depletion is primarily caused by certain chemicals called ozone-depleting substances like chlorofluorocarbons (CFCs). While reducing carbon emissions can help mitigate climate change, addressing ozone depletion requires phasing out ozone-depleting substances.
The use of CFC contributed to depletion of ozone. It is because they react with ozone to decompose it.
Firecrackers can potentially release pollutants into the atmosphere which can contribute to ozone depletion. However, the impact of firecrackers on the ozone layer is relatively small compared to other human activities such as industrial emissions and vehicle exhaust. It is important to limit the use of firecrackers to protect the environment.
