I know it is pisssing into the wind here, but we all know that CO2 is NOT a pollutant! It is the stuff that plants turn back into oxygen! The rest of the stuff, yea, that should be controlled, and already IS. But the silliness of the argument that acid rain is created... Has anyone ever SEEN acid rain outside of a controlled lab environment? The conditions have to be VERY specific for it to happen, and IF it ever occurred in nature, it hasn't happened in 20 years
Well, don't want to get into a urinating contest over this issue, but the quote above is simply wrong.
Geordi is correct that plants use CO2. They do release Oxygen as a consequence of the reaction using chlorophyll to produce energy. However, they don't "use" CO2 to produce O2.
Acid rain is a real consequence of fossil fuel combustion. Without getting into the chemistry of the reaction, which is well known and easily reproduced, sulfur dioxide and/or nitrous oxides (which are produced in the combustion process) combine with water droplets in clouds to produce sulfuric/sulfurous acid and nitric acid yielding acidic rainwater which falls to earth as acid rain. This rainwater can be very acidic and have a ph (measurement of its acidity) of 4-5 which is about the same as lemon juice.
Although the relative amount of acid rain has been reduced due to pollution controls it remains a huge problem in all down wind areas, especially in the north east US. The problem of acid rain continues to this day and did not end "20 years ago". The issue also goes beyond just making lakes and ponds acid. The acidic water interferes with the life cycle of all aquatic organisms and also effects plants and trees as it degrades the ability of green plants to use their chlorophyll properly (and thus reduces the oxygen "produced"). If you don't believe it continues to be a real problem, simply look at graves markers in New England cemeteries and see how the stone has been attacked by the acid water.
Lastly, while CO2 is not a "pollutant" in the truest sense of the word, it is a strong contributor to global warming and needs continuing control. A good comparison to the problem of over productin of CO2 is water, which is also not a "pollutant", but when there is too much and floods occur it is also a big problem.
Denying the science does not change the facts. The truth is not always pleasant, but it is still the truth
