Fossil fuel<\/strong><\/p>\n<p>Ozone is a gas that is found in two layers in the Earth&#8217;s atmosphere. The ozone layer, which is located in the stratosphere, protects the Earth from harmful ultraviolet radiation. Ground-level ozone, on the other hand, is a major air pollutant that can cause respiratory problems, heart disease, and cancer.<\/p>\n<p>Ground-level ozone is formed when sunlight reacts with certain chemicals in the air, such as nitrogen oxides and volatile organic compounds (VOCs). These chemicals are released into the air from a variety of sources, including cars, trucks, power plants, and industrial facilities.<\/p>\n<p>Fossil fuels, such as coal, oil, and natural gas, are the primary source of nitrogen oxides and VOCs. When these fuels are burned, they release these chemicals into the air. In addition, fossil fuels can also release other pollutants, such as sulfur dioxide and particulate matter, which can contribute to the formation of ground-level ozone.<\/p>\n<p>CFCs, or chlorofluorocarbons, are a type of chemical that was once widely used in refrigerators, air conditioners, and other products. However, CFCs are also very effective at destroying ozone in the stratosphere. As a result, the production and use of CFCs was banned in 1996 <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> under the Montreal Protocol.<\/p>\n<p>Oxygen is a <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> gas that is essential for life.
