Sustainable Building Forum

I'm new to all the global warming research, but I have a question for the community.  A lot of evidence has shown temperatures are rising.  There doesn't seem to be much consensus of what is causing it.  Is it wrong for me to think that since each human's body temperature is 98.6 degrees and there are ~8 billion people in the world, that that might contribute to global warming. 

I don't think that has an impact, it is in the same class as, with all those people, will we get out of orbit, like gravity out of control, or when we all jump at the same time.

The cattle 'cows, sheep, chicken' that 8 billion people need is a bigger issue of coČ emission than all our cars, so the biggest part of this is because Mc Donalds needs millions of cows a year for their hamburgers, the emission from farting (cows fart) are 10 times higher than all industry (factories, cars) combined.

I was just reading a news article at Aol.com about global warming and there was quite a bit of discussion about causes, etc.  Many brought up the cows as being more of a cause than humans.  The flaw in this logic is that cows exist BECAUSE of humans, right?  We have chosen to consume huge amounts of beef even though other meats are better for us.  As to McDonald's beef consumption, is that not also the fault of all of us who purchase those billions of hamburgers?
