Plants pull 100 gigatons of carbon out of the atmosphere every year and convert it to biomass (essentially, oxy-ammonia-hydrocarbons like sugars, proteins, fats, etc.). Humans pull about 6 gigatons of carbon out of the ground each year and pump it into the atmosphere.
The reason this cycle doesn't exhaust the atmospheric pool, of course, is that animals and fungi (more the latter) break down biomass into CO2 and release it back into the atmosphere.
That's not what I'd call 'very very little carbon'.
