If its the latter, let me know and I will stop posting. I had no problem with English comprehension until your last post (quoted above) which seems totally unrelated to our previous conversation. I was argueing that CO2 is not a pollutant. I said it was uubiquitous and non-toxic. You replied that "sometimes too much of a good thing can be toxic. I replied that like water or nitrogen we can suffocate if surrounded by it but that CO2 is not toxic, "not on the levels that we encounter it on earth, or even at much higher levels." Tim there is a lake in the NW part of Cameroon here on Earth. That lake sits on a large concentration of CO2. In the mid 80's, the lake burped and let out a large cloud of CO2. That cloud ended up smothering hundreds of the surrounding residents.You talk about how too much of a good thing can be bad. You give the examples of O2, water, and hot fudge sundaes. Those provide perfect examples of examples of non-toxic, non pollutants that can be bad if you have too much of them. Thus unless you are maintaining that O2, H2O and hot fuge sundaes are toxic pollutants you support my arguement that CO2 is not toxic or a pollutant. I didn't say that it can't be a bad thing if we have to much, I said it was not toxic and not a pollutant. Toxic means poisonous, harmful [to living organisms]. In the case above, the CO2 definitely was harmful, toxic to the residents around this lake. In that minute at a certain level of concentration, the CO2 became deadly and a killer. It no longer was the good gas that you speak of so fondly. Now you complain ad infinitum that Scumbria will not concede a point or admit when he is wrong. If that's true, apparently it takes one to know one. ted
