I know the mods are going to cut this discussion off here any minute but he had it right. Plants emit oxygen during PHOTOSYNTHISIS and CO2 during RESPERATION. And not to cause a flame war or political turmoil, the warming and cooling of the earth (build up of "green house gasses") has happened many times in the earth's history. Are we accelerating it, maybe (I am not fully convinced), but we are not the cause of global warming. It is a natural cycle of the planet. There will be warm periods followed by Ice Ages. It has happened before, it will happen again. I consider it arrogance to think that we as a species can destroy this planet. It is possible that it may become so that we cannot live here but give it a few million or so years and something else might. Just so people don't think I hate the environment, I do believe in reducing our affect on nature, conserving forests (I love hiking in them, particularly the redwoods of northern California), reusing and recycling where it makes sense, and reducing our reliance on petroleum as soon as it is feasible. And, just to add some Delorean content, I really think we need to get to work on building real power sources like "Mr. Fusion" for electric cars that work well and are practical... Any ideas anyone?

First, plants emit oxygen during respiration, they "breathe" in CO2. And it IS a greenhouse gas, if that is what you mean by "the environmentalists," there are measurements of CO2 and other gasses that have risen at alarming rates over the past 100 years. It IS causing the global warming issue. And any gas (even oxygen) in excess is poisonous. Now to get back to the cars, not biology or chemistry... The car is fine, and so is the family.

It's NOT a pollutant, despite what the environmentalists will have you believe. It is also not odourless in high concentrations (like the top of a freshly poured glass of fizzy drink, or a fire extinguisher). What you're talking about is simple lack of oxygen, not the effect of CO2 - and you would most likely wake up in that unlikely event. Carbon monoxide is very, very poisonous and has the effect of replacing oxygen in the bloodstream, IIRC. A person inhaling it in their sleep will never know because it causes unconsciosness. I'm not arguing against responsible use of CO alarms, but CO2 is not a dangerous gas, and a car equipped with a cat will emit only tiny amounts of CO. Try putting a CO meter up the exhaust of a DeLorean with a cat, and see how much it reads. I regularly work with de-catted DeLoreans and adjust the mixture using my CO meter, which should be 1% for a lambda equipped engine and 1.5-2% CO for a B28E metering equipped engine (popular over here for the added performance).
