Eh, not really. The stuff we eat, and by extension the CO2 and waste we put out, has been a regular part of the global carbon cycle for millions of years. (cattle is a different issue because they produce methane)
Fossil fuels are essentially carbon materials that have been removed from the global environment for millions, or dozens of millions of years. Sure, Earth was warmer in those days, but the Earth's ecological system nowadays would be in for a shock if all that carbon material is added to the cycle again.
