At natural levels of greenhouse gases in the atmosphere (before the Industrial Revolution), the carbon cycle moved carbon dioxide in and out of land, sea and air. Enough carbon dioxide remained in the atmosphere to keep the earth comfortably warm, warm enough for life.
Chlorofluorocarbon (CFC) gases used in refrigeration
Ozone is made both by Nature (ozone layer, lightning, waterfalls, and as an oxidant produced to fight infection), by Man (oxidant used for many industrial, and commercial uses), and by both together (ozone pollution).
The natural components of the atmosphere doesn't react each other.
The industrial gas industry differs from many other types of manufacturing because its raw materials are primarily extracted from the atmosphere. The two principal gases produced by the industry are nitrogen and oxygen.
the death of plants and animals release nitrogen and carbon dioxide gases

Gasoline and diesel automobiles and trucks pollute as do industries which burn coal. Some industrial processes such as oil refineries give off gases which pollute. Cows give off methane.
Weather moves gases in the atmosphere
Weather moves gases into the atmosphere.
Since the Industrial Revolution we have been burning fossil fuels (coal, oil and natural gas). This burning releases EXTRA carbon dioxide into the atmosphere, some of which is NOT removed by the carbon cycle. These greenhouse gases capture the sun's heat as it comes off the earth and warms the atmosphere. As the gases build up, so the world is getting warmer. This is global warming.
