c. respiration

Respiration is a natural biological process (part of the carbon cycle) and not a manmade source of the increased greenhouse gases driving recent global warming. Burning fossil fuels, deforestation, and growing population are human-driven factors that increase net CO2 and other greenhouse gas emissions.
