Rats, I'm sorry to have given you the wrong impression in that case: <I believe this started out when you said more CO2 is good and I said CO2 will kill, at least on the microenvironmental level. It is foolish to think atmospheric changes in CO2 would be individually toxic. Any changes would be so slow that adaptation of the organism would occur; not even evolution per se, but just thru changes in sensitivity of the various receptors to CO2,pH. Howsomever, my point was that CO2 is a toxic gas. Since you seem to be skeptical,... > I accept that CO2 is toxic if you get enough of it. I explained that and used selenium as another example of what happens when we get too much of an otherwise good thing. When I say more CO2 is good, I mean for plants and our food supplies and to avoid an ice age. Not that we'll get a kick out of inhaling it. We have enough and our bodies are working to ensure levels don't get any higher than our happily resting respiratory rate. I notice when I get going uphill on the golf course, I breathe heavier. My understanding was that that's because my blood CO2 is building up too much and I have to puff away to keep the air rapidly moving in and out of my lungs to get rid of more CO2 and do it quickly. I need to lower the partial pressure of CO2 in my lungs. At the 400 ppm level, I don't have a problem with breathing rate, because that's well within the realms of normal breathing levels. As you commented, even that level will have an effect on the breathing-impaired because the higher the partial pressure of CO2, the tougher job they have to keep their respiratory systems functioning well. I'm just saying that more CO2 is good up to maybe 500 ppm. It's plant food and they love having lots in the air. We like having plants [so do a lot of insects and other beasties]. It also keeps us warm and avoids ice ages. Mqurice PS: You seem a little too enthusiastic to demonstrate on me what happens if I was to breathe too much CO2. Are you sure you would take the mask off at the right time if we were doing that in your basement? <if you want to come to my place some night, I'll grab a tank and we can go down to the lab; >

"...ask them to run an experiment on you, using carbogen (mix of CO2, O2). If Maurice is still kicking after that, you can then run some dihydrogen monoxide tests on him for good measure. Dihydrogen monoxide is colorless, odorless, tasteless, and kills uncounted thousands of people every year. Most of these deaths are caused by accidental inhalation of DHMO, but the dangers of dihydrogen monoxide do not end there. Prolonged exposure to its solid form causes severe tissue damage. Symptoms of DHMO ingestion can include excessive sweating and urination, and possibly a bloated feeling, nausea, vomiting and body electrolyte imbalance. For those who have become dependent, DHMO withdrawal means certain death. Dihydrogen monoxide: * is also known as hydroxl acid, and is the major component of acid rain. * contributes to the "greenhouse effect." * may cause severe burns. * contributes to the erosion of our natural landscape. * accelerates corrosion and rusting of many metals. * may cause electrical failures and decreased effectiveness of automobile brakes. * has been found in excised tumors of terminal cancer patients. Contamination is reaching epidemic proportions! Quantities of dihydrogen monoxide have been found in almost every stream, lake, and reservoir in America today. But the pollution is global, and the contaminant has even been found in Antarctic ice. DHMO has caused millions of dollars of property damage in the midwest, and recently California. Despite the danger, dihydrogen monoxide is often used: * as an industrial solvent and coolant. * in nuclear power plants. * in the production of styrofoam. * as a fire retardant. * in many forms of cruel animal research. * in the distribution of pesticides. Even after washing, produce remains contaminated by this chemical. * as an additive in certain "junk-foods" and other food products. Companies dump waste DHMO into rivers and the ocean, and nothing can be done to stop them because this practice is still legal. The impact on wildlife is extreme, and we cannot afford to ignore it any longer! The American government has refused to ban the production, distribution, or use of this damaging chemical due to its "importance to the economic health of this nation." In fact, the navy and other military organizations are conducting experiments with DHMO, and designing multi-billion dollar devices to control and utilize it during warfare situations. Hundreds of military research facilities receive tons of it through a highly sophisticated underground distribution network. Many store large quantities for later use. snopes2.com ig
