CFCs are very stable and do not react with other chemicals easily. However, they are also very good at breaking down ozone molecules in the atmosphere. Ozone is a gas that protects the Earth from harmful ultraviolet radiation from the sun. When CFCs break down ozone molecules, they release chlorine atoms, which react with ozone molecules and destroy them. This process of ozone depletion has led to an increase in the amount of ultraviolet radiation reaching the Earth&#8217;s surface, which has increased the risk of skin cancer and other health problems.<\/p>\n<p>A. Nitrous oxide is a greenhouse gas that contributes to climate change. It is not a major contributor to ozone depletion.<\/p>\n<p>B. Carbon dioxide is another greenhouse gas that contributes to climate change. It is not a major contributor to ozone depletion.<\/p>\n<p>D. Sulphur dioxide is a pollutant that can cause acid rain.
