CFCs.<\/p>\n<p>CFCs (chlorofluorocarbons) are a group of man-made chemicals that were once widely used in refrigerators, air conditioners, and aerosol cans. They are also used in some industrial processes. CFCs are very stable and do not break down easily in the atmosphere. When they reach the stratosphere, they are broken down by ultraviolet radiation and release chlorine atoms. These chlorine atoms react with ozone molecules, destroying them.<\/p>\n<p>Nitrous oxide (N2O) is a greenhouse gas that is also a contributor to ozone depletion. It is produced by natural processes, such as the decomposition of organic matter, and by human activities, such as the burning of fossil fuels. Nitrous oxide breaks down in the stratosphere and releases nitrogen oxides, which react with ozone molecules.<\/p>\n<p>SF6 (sulfur hexafluoride) is a greenhouse gas that is also a contributor to ozone depletion. It is used in electrical equipment and as a fire suppressant. SF6 breaks down in the stratosphere and releases sulfur atoms, which react with ozone molecules.<\/p>\n<p>PFCs (perfluorocarbons) are a group of man-made chemicals that are very stable <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> and do not break down easily in the atmosphere.
