The article explores how small industries release gases that lead to global warming. These emissions cause the Earth to get hotter, raising sea levels and risking animals' and insects' survival. The researchers calculated the gases released by small industries, like carbon dioxide and methane, using simple math. They also figured out how much gas fossil fuels used in mills produce. By evaluating data from combined heat and power plants, they estimated the gases produced, helping to understand how industries affect the environment.
