Respiration is not a manmade cause of global warming. Correct answer: C  

Global warming is caused by emitting greenhouse gasses in the atmosphere. Carbon dioxide (CO2), methane, nitrous oxide, water vapor and ozone are among the most prevalent.  CO2, largely result from respiration, and respiration is a natural process.
