I was talking to a skeptic on global warming who said that a major contribution to increasing levels of carbon dioxide in the atmosphere is the large global population. This person claims that humans breathe out so much carbon dioxide this contributes to global warming just as much as the burning of fossil fuels. Is there any way to compare humans breathing out carbon dioxide and the carbon dioxide produced by electrical use of fossil fuels world wide?

According to Wikipedia ( http://en.wikipedia.org/wiki/Carbon_dioxide )the average human being emits 900gm of CO2 per day. Taking the world population as 6 billion this equates to .9/1000x6x365=2 billion tonnes of CO2 per year. Also according to Wikipedia the annual emission of CO2 due to burning fossil fuels is 24 billion tonnes.

That question is not really possible to answer because not all people do the same kind of work throughout their life: some people may do many vigorous activities that may cause them to exhale large amounts of carbon dioxide. On the other hand, there might be people who just sit on their couch all day, watching TV, which does not result in exhaling as much carbon dioxide.

345 ,698 cubic metres of carbon dioxide is exhaled on average for a person with a life span of 60 years.
