Which human activities contribute to greenhouse gas concentrations?

Explanation:
All of the listed activities contribute to greenhouse gas concentrations. Burning fossil fuels releases carbon dioxide directly into the atmosphere. Agriculture and waste management bring in methane and nitrous oxide through processes like enteric digestion in ruminant animals, manure management, rice paddies, and fertilizer use. Industrial processes release fluorinated gases such as HFCs, PFCs, and SF6, used in refrigeration, solvents, and manufacturing. Each of these pathways adds different greenhouse gases with the ability to trap heat, so together they increase the overall concentration of greenhouse gases in the air.
