too much CO2 will cause the lungs to restrict the flow of air.
The more O2 that enter, the more energy a person will have.
Do you even know what the topic is about? Your replies have nothing to do with what anyone has said. They're not even remotely related to the topic.
This Greenhouse crap is going to far. we're trying to make up excuses while here in the States that we're having an obesity problem while other countries like for example," Jamaica" that breathing in more CO2 because it in a part of the world that the humidity is very high, isn't having any fat issues. It seem like everyone is trying to put blame on the natural events that been going in the past decades, but over-looking the facts that's in front of their faces.
No one here made any excuses. This is simple science.
What part of the hypothesis or what the authors did is science? They proposed a hypothesis that they did not attempt to falsify but, instead, performed a non-blind, uncontrolled experiment in which 3 of 6 people were exposed to CO2 concentrations many orders of magnitude greater than normal air, and didn’t get statistically significant results. Then they proposed useless, unscientific animal-model experiments, the results of which they acknowledge will not determine anything about their hypothesis concerning the recent obesity epidemic seen among humans in some societies. Where’s the science in any of that?
