when whatever is being vurnt and remade in a factory happens there is a residue which turns to gas and this pollutes the air with bad and sometimes toxic substances which can rain down onto crops and farms eventually hitting us when we eat what is grown around there-
When burned, these fossil fuels emit harmful gases including carbon dioxide and sulfur dioxide which increase the amount of greenhouse gases in the atmosphere resulting in global warming. Air pollution is much worse in highly populated cities where more factories emit pollution in close proximity to humans.
