Global Warming and our Changing World

Today I had the idea that what if part of the reason the earth is warmer is because there are more warm bodies running around? Six billion is a record for worldwide population, right? And in "The Matrix," the body heat from "endless fields" of people was powerful enough to power the machine society. So why not?

What if there are so many people on earth that just being alive, you're contributing to global warming? What if the true source of the problem isn't the burning of fossil fuels, but is the conversion of food energy to heat energy through our normal biological processes?

If that were the case, I'm sure we could still set things right. We'd just have to do so through new forms of research and technology.
