Fossil fuels contain sulfur and nitrogen, sulfur dioxide, nitric oxide and nitrogen dioxide are released after combustion, these gases will directly or indirectly lead to the formation of acid rain, in addition, the main combustion product of fossil fuels is carbon dioxide, a large amount of carbon dioxide wrapped around the earth to prevent the loss of heat from the earth, so that the temperature of the earth gradually increases.
Some of the products of fossil fuel combustion are polluting, such as CO, NO, nitrogen dioxide, sulfur dioxide, carbon dioxide, and some organic matter.
And some of these combustion products can cause the greenhouse effect, such as carbon dioxide and other organic matter, which causes a more serious greenhouse effect than carbon dioxide.

This is wrong, completely misleading, and it was even chosen, "such as carbon dioxide and other organic matter, they cause a more serious greenhouse effect than carbon dioxide." "- You look with your eyes wide open, is this Chinese?? And sulfur dioxide is not the cause of greenhouses, but reduces the inhibitory elements of greenhouses, simply put, it is an anti-greenhouse gas, but it will cause acid rain, which is also a pollutant.

It doesn't matter, sulfur dioxide is just toxic.
Substances related to the greenhouse effect: carbon dioxide, methane, ozone, fluorofluoroalkanes, etc.

Carbon dioxide exacerbates the temperature-in-the-rock chamber effect, resulting in sulfur dioxide and nitrogen dioxide that can lead to acid rain.
Behind the scenes of acid rain is sulfur dioxide and nitrogen dioxide, but the sulfuric acid in acid rain is larger. The dangers of acid rain are enormous. They can directly endanger human health, cause respiratory diseases, and in severe cases, cause death; It can also directly damage crops, forests, grasslands, acidify soils and lakes, and accelerate the corrosion of buildings, bridges, industrial equipment, transportation vehicles and telecommunication cables.
Hazards of Acid Rain:
1. Acid rain can lead to soil acidification, and acid rain can still accelerate the loss of soil mineral nutrients; Changing the soil structure, leading to soil impoverishment, affecting the normal development of plants; Acid rain can also induce plant pests and diseases, which can significantly reduce crop yields.
2. Acid rain can cause great harm to forest plants. The longer the leaves are in contact with acid rain, the more severe the damage will be. In areas with less than the pH value of precipitation, a large number of yellow leaves appeared in the Masson pine forest, Huashan pine and fir forest, and the forest fell off in patches.
Sulphur dioxide is a relatively safe preservative.
Sulphur dioxide in food. Sulfur dioxide is an important member of inorganic chemical preservatives. Sulphur dioxide has been used as a food additive for centuries, with the earliest recorded use in Roman times to disinfect wine vessels. >>>More

Based on the similarity between sulfur dioxide and carbon dioxide in non-redox reactions, I think Cu can be generated with SO2 in a humid environment Basic copper sulfite : 2Cu + O2 + SO2 + H2O == Cu2(OH)2SO3 I remember that at high temperatures, by oxidizing sulfide ores, to convert into oxides, and then for reduction, is a common way to refine some metals in the form of sulfides, such as oxidizing Cu2S or Cus with O2, so that they can produce Cuo and SO2. This phenomenon shows that the sulfides of copper are not as stable as oxides, and the elemental substances are not as stable as oxides, so it is unlikely that Cu and SO2 react at high temperatures to form Cuo and S.
