>Name an ideal ratio of CO2, nitrogen, oxygen, and H2O in the environment. Cite it with sources. Um, it's common sense. Human beings' lungs evolved (if you believe in evolution) to be able to be able to extract a certain amount of oxygen from a certain mix of air. If you change that mix, it's going to be harder for people to breathe. But I didn't even mean to take the conversation to that point. I'm not sure why I did. The bigger concern is the greenhouse effect, which is due to increased concentrations of greenhouse gases such as CO2. I'm sure you're familiar. In fact, I think, in the past, you've acknowledged that it's an issue and that humans are causing it. You just think we should ignore it and adapt, no? -Z
